For example: - * <pre> - * Uri uri = Uri.parse("https://www.example.com"); - * Intent intent = new Intent(Intent.ACTION_VIEW, uri); - * startActivity(intent); - * </pre> - * <p>See {@link android.content.Intent} for more information. - * - * <p>To provide a WebView in your own Activity, include a {@code <WebView>} in your layout, - * or set the entire Activity window as a WebView during {@link - * android.app.Activity#onCreate(Bundle) onCreate()}: - * - * <pre class="prettyprint"> - * WebView webview = new WebView(this); - * setContentView(webview); - * </pre> - * - * <p>Then load the desired web page: - * - * <pre> - * // Simplest usage: note that an exception will NOT be thrown - * // if there is an error loading this page (see below). - * webview.loadUrl("https://example.com/"); - * - * // OR, you can also load from an HTML string: - * String summary = "<html><body>You scored <b>192</b> points.</body></html>"; - * webview.loadData(summary, "text/html", null); - * // ... although note that there are restrictions on what this HTML can do. - * // See the JavaDocs for {@link #loadData(String,String,String) loadData()} and {@link - * #loadDataWithBaseURL(String,String,String,String,String) loadDataWithBaseURL()} for more info. - * </pre> - * - * <p>A WebView has several customization points where you can add your - * own behavior. These are: - * - * <ul> - * <li>Creating and setting a {@link android.webkit.WebChromeClient} subclass. - * This class is called when something that might impact a - * browser UI happens, for instance, progress updates and - * JavaScript alerts are sent here (see <a - * href="{@docRoot}guide/developing/debug-tasks.html#DebuggingWebPages">Debugging Tasks</a>). - * </li> - * <li>Creating and setting a {@link android.webkit.WebViewClient} subclass. - * It will be called when things happen that impact the - * rendering of the content, eg, errors or form submissions. You - * can also intercept URL loading here (via {@link - * android.webkit.WebViewClient#shouldOverrideUrlLoading(WebView,String) - * shouldOverrideUrlLoading()}).</li> - * <li>Modifying the {@link android.webkit.WebSettings}, such as - * enabling JavaScript with {@link android.webkit.WebSettings#setJavaScriptEnabled(boolean) - * setJavaScriptEnabled()}. </li> - * <li>Injecting Java objects into the WebView using the - * {@link android.webkit.WebView#addJavascriptInterface} method. This - * method allows you to inject Java objects into a page's JavaScript - * context, so that they can be accessed by JavaScript in the page.</li> - * </ul> - * - * <p>Here's a more complicated example, showing error handling, - * settings, and progress notification: - * - * <pre class="prettyprint"> - * // Let's display the progress in the activity title bar, like the - * // browser app does. - * getWindow().requestFeature(Window.FEATURE_PROGRESS); - * - * webview.getSettings().setJavaScriptEnabled(true); - * - * final Activity activity = this; - * webview.setWebChromeClient(new WebChromeClient() { - * public void onProgressChanged(WebView view, int progress) { - * // Activities and WebViews measure progress with different scales. - * // The progress meter will automatically disappear when we reach 100% - * activity.setProgress(progress * 1000); - * } - * }); - * webview.setWebViewClient(new WebViewClient() { - * public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) { - * Toast.makeText(activity, "Oh no! " + description, Toast.LENGTH_SHORT).show(); - * } - * }); - * - * webview.loadUrl("https://developer.android.com/"); - * </pre> - * - * <h3>Zoom</h3> - * - * <p>To enable the built-in zoom, set - * {@link #getSettings() WebSettings}.{@link WebSettings#setBuiltInZoomControls(boolean)} - * (introduced in API level {@link android.os.Build.VERSION_CODES#CUPCAKE}). - * - * <p>NOTE: Using zoom if either the height or width is set to - * {@link android.view.ViewGroup.LayoutParams#WRAP_CONTENT} may lead to undefined behavior - * and should be avoided. - * - * <h3>Cookie and window management</h3> - * - * <p>For obvious security reasons, your application has its own - * cache, cookie store etc.—it does not share the Browser - * application's data. - * - * <p>By default, requests by the HTML to open new windows are - * ignored. This is {@code true} whether they be opened by JavaScript or by - * the target attribute on a link. You can customize your - * {@link WebChromeClient} to provide your own behavior for opening multiple windows, - * and render them in whatever manner you want. - * - * <p>The standard behavior for an Activity is to be destroyed and - * recreated when the device orientation or any other configuration changes. This will cause - * the WebView to reload the current page. If you don't want that, you - * can set your Activity to handle the {@code orientation} and {@code keyboardHidden} - * changes, and then just leave the WebView alone. It'll automatically - * re-orient itself as appropriate. Read <a - * href="{@docRoot}guide/topics/resources/runtime-changes.html">Handling Runtime Changes</a> for - * more information about how to handle configuration changes during runtime. - * - * - * <h3>Building web pages to support different screen densities</h3> - * - * <p>The screen density of a device is based on the screen resolution. A screen with low density - * has fewer available pixels per inch, where a screen with high density - * has more — sometimes significantly more — pixels per inch. The density of a - * screen is important because, other things being equal, a UI element (such as a button) whose - * height and width are defined in terms of screen pixels will appear larger on the lower density - * screen and smaller on the higher density screen. - * For simplicity, Android collapses all actual screen densities into three generalized densities: - * high, medium, and low. - * <p>By default, WebView scales a web page so that it is drawn at a size that matches the default - * appearance on a medium density screen. So, it applies 1.5x scaling on a high density screen - * (because its pixels are smaller) and 0.75x scaling on a low density screen (because its pixels - * are bigger). - * Starting with API level {@link android.os.Build.VERSION_CODES#ECLAIR}, WebView supports DOM, CSS, - * and meta tag features to help you (as a web developer) target screens with different screen - * densities. - * <p>Here's a summary of the features you can use to handle different screen densities: - * <ul> - * <li>The {@code window.devicePixelRatio} DOM property. The value of this property specifies the - * default scaling factor used for the current device. For example, if the value of {@code - * window.devicePixelRatio} is "1.0", then the device is considered a medium density (mdpi) device - * and default scaling is not applied to the web page; if the value is "1.5", then the device is - * considered a high density device (hdpi) and the page content is scaled 1.5x; if the - * value is "0.75", then the device is considered a low density device (ldpi) and the content is - * scaled 0.75x.</li> - * <li>The {@code -webkit-device-pixel-ratio} CSS media query. Use this to specify the screen - * densities for which this style sheet is to be used. The corresponding value should be either - * "0.75", "1", or "1.5", to indicate that the styles are for devices with low density, medium - * density, or high density screens, respectively. For example: - * <pre> - * <link rel="stylesheet" media="screen and (-webkit-device-pixel-ratio:1.5)" href="hdpi.css" /></pre> - * <p>The {@code hdpi.css} stylesheet is only used for devices with a screen pixel ration of 1.5, - * which is the high density pixel ratio. - * </li> - * </ul> - * - * <h3>HTML5 Video support</h3> - * - * <p>In order to support inline HTML5 video in your application you need to have hardware - * acceleration turned on. - * - * <h3>Full screen support</h3> - * - * <p>In order to support full screen — for video or other HTML content — you need to set a - * {@link android.webkit.WebChromeClient} and implement both - * {@link WebChromeClient#onShowCustomView(View, WebChromeClient.CustomViewCallback)} - * and {@link WebChromeClient#onHideCustomView()}. If the implementation of either of these two methods is - * missing then the web contents will not be allowed to enter full screen. Optionally you can implement - * {@link WebChromeClient#getVideoLoadingProgressView()} to customize the View displayed whilst a video - * is loading. - * - * <h3>HTML5 Geolocation API support</h3> - * - * <p>For applications targeting Android N and later releases - * (API level > {@link android.os.Build.VERSION_CODES#M}) the geolocation api is only supported on - * secure origins such as https. For such applications requests to geolocation api on non-secure - * origins are automatically denied without invoking the corresponding - * {@link WebChromeClient#onGeolocationPermissionsShowPrompt(String, GeolocationPermissions.Callback)} - * method. - * - * <h3>Layout size</h3> - * <p> - * It is recommended to set the WebView layout height to a fixed value or to - * {@link android.view.ViewGroup.LayoutParams#MATCH_PARENT} instead of using - * {@link android.view.ViewGroup.LayoutParams#WRAP_CONTENT}. - * When using {@link android.view.ViewGroup.LayoutParams#MATCH_PARENT} - * for the height none of the WebView's parents should use a - * {@link android.view.ViewGroup.LayoutParams#WRAP_CONTENT} layout height since that could result in - * incorrect sizing of the views. - * - * <p>Setting the WebView's height to {@link android.view.ViewGroup.LayoutParams#WRAP_CONTENT} - * enables the following behaviors: - * <ul> - * <li>The HTML body layout height is set to a fixed value. This means that elements with a height - * relative to the HTML body may not be sized correctly. </li> - * <li>For applications targeting {@link android.os.Build.VERSION_CODES#KITKAT} and earlier SDKs the - * HTML viewport meta tag will be ignored in order to preserve backwards compatibility. </li> - * </ul> - * - * <p> - * Using a layout width of {@link android.view.ViewGroup.LayoutParams#WRAP_CONTENT} is not - * supported. If such a width is used the WebView will attempt to use the width of the parent - * instead. - * - * <h3>Metrics</h3> - * - * <p> - * WebView may upload anonymous diagnostic data to Google when the user has consented. This data - * helps Google improve WebView. Data is collected on a per-app basis for each app which has - * instantiated a WebView. An individual app can opt out of this feature by putting the following - * tag in its manifest: - * <pre> - * <meta-data android:name="android.webkit.WebView.MetricsOptOut" - * android:value="true" /> - * </pre> - * <p> - * Data will only be uploaded for a given app if the user has consented AND the app has not opted - * out. - * - * <h3>Safe Browsing</h3> - * - * <p> - * If Safe Browsing is enabled, WebView will block malicious URLs and present a warning UI to the - * user to allow them to navigate back safely or proceed to the malicious page. - * <p> - * The recommended way for apps to enable the feature is putting the following tag in the manifest: - * <p> - * <pre> - * <meta-data android:name="android.webkit.WebView.EnableSafeBrowsing" - * android:value="true" /> - * </pre> + * Mock version of the WebView. + * Only non override public methods from the real WebView have been added in there. + * Methods that take an unknown class as parameter or as return object, have been removed for now. + * + * TODO: generate automatically. * */ -// Implementation notes. -// The WebView is a thin API class that delegates its public API to a backend WebViewProvider -// class instance.

This means that any method - * handle made visible to the application will always be fully formed. - * This is true even if the method handle is published through a shared - * variable in a data race. - * <p> - * Method handles cannot be subclassed by the user. - * Implementations may (or may not) create internal subclasses of {@code MethodHandle} - * which may be visible via the {@link java.lang.Object#getClass Object.getClass} - * operation. The programmer should not draw conclusions about a method handle - * from its specific class, as the method handle class hierarchy (if any) - * may change from time to time or across implementations from different vendors. - * - * <h1>Method handle compilation</h1> - * A Java method call expression naming {@code invokeExact} or {@code invoke} - * can invoke a method handle from Java source code. - * From the viewpoint of source code, these methods can take any arguments - * and their result can be cast to any return type. - * Formally this is accomplished by giving the invoker methods - * {@code Object} return types and variable arity {@code Object} arguments, - * but they have an additional quality called <em>signature polymorphism</em> - * which connects this freedom of invocation directly to the JVM execution stack. - * <p> - * As is usual with virtual methods, source-level calls to {@code invokeExact} - * and {@code invoke} compile to an {@code invokevirtual} instruction. - * More unusually, the compiler must record the actual argument types, - * and may not perform method invocation conversions on the arguments. - * Instead, it must push them on the stack according to their own unconverted types. - * The method handle object itself is pushed on the stack before the arguments. - * The compiler then calls the method handle with a symbolic type descriptor which - * describes the argument and return types. - * <p> - * To issue a complete symbolic type descriptor, the compiler must also determine - * the return type. This is based on a cast on the method invocation expression, - * if there is one, or else {@code Object} if the invocation is an expression - * or else {@code void} if the invocation is a statement. - * The cast may be to a primitive type (but not {@code void}). - * <p> - * As a corner case, an uncasted {@code null} argument is given - * a symbolic type descriptor of {@code java.lang.Void}. - * The ambiguity with the type {@code Void} is harmless, since there are no references of type - * {@code Void} except the null reference. - * - * <h1>Method handle invocation</h1> - * The first time a {@code invokevirtual} instruction is executed - * it is linked, by symbolically resolving the names in the instruction - * and verifying that the method call is statically legal. - * This is true of calls to {@code invokeExact} and {@code invoke}. - * In this case, the symbolic type descriptor emitted by the compiler is checked for - * correct syntax and names it contains are resolved. - * Thus, an {@code invokevirtual} instruction which invokes - * a method handle will always link, as long - * as the symbolic type descriptor is syntactically well-formed - * and the types exist. - * <p> - * When the {@code invokevirtual} is executed after linking, - * the receiving method handle's type is first checked by the JVM - * to ensure that it matches the symbolic type descriptor. - * If the type match fails, it means that the method which the - * caller is invoking is not present on the individual - * method handle being invoked. - * <p> - * In the case of {@code invokeExact}, the type descriptor of the invocation - * (after resolving symbolic type names) must exactly match the method type - * of the receiving method handle. - * In the case of plain, inexact {@code invoke}, the resolved type descriptor - * must be a valid argument to the receiver's {@link #asType asType} method. - * Thus, plain {@code invoke} is more permissive than {@code invokeExact}. - * <p> - * After type matching, a call to {@code invokeExact} directly - * and immediately invoke the method handle's underlying method - * (or other behavior, as the case may be). - * <p> - * A call to plain {@code invoke} works the same as a call to - * {@code invokeExact}, if the symbolic type descriptor specified by the caller - * exactly matches the method handle's own type. - * If there is a type mismatch, {@code invoke} attempts - * to adjust the type of the receiving method handle, - * as if by a call to {@link #asType asType}, - * to obtain an exactly invokable method handle {@code M2}. - * This allows a more powerful negotiation of method type - * between caller and callee. - * <p> - * (<em>Note:</em> The adjusted method handle {@code M2} is not directly observable, - * and implementations are therefore not required to materialize it.) - * - * <h1>Invocation checking</h1> - * In typical programs, method handle type matching will usually succeed. - * But if a match fails, the JVM will throw a {@link WrongMethodTypeException}, - * either directly (in the case of {@code invokeExact}) or indirectly as if - * by a failed call to {@code asType} (in the case of {@code invoke}). - * <p> - * Thus, a method type mismatch which might show up as a linkage error - * in a statically typed program can show up as - * a dynamic {@code WrongMethodTypeException} - * in a program which uses method handles. - * <p> - * Because method types contain "live" {@code Class} objects, - * method type matching takes into account both types names and class loaders. - * Thus, even if a method handle {@code M} is created in one - * class loader {@code L1} and used in another {@code L2}, - * method handle calls are type-safe, because the caller's symbolic type - * descriptor, as resolved in {@code L2}, - * is matched against the original callee method's symbolic type descriptor, - * as resolved in {@code L1}. - * The resolution in {@code L1} happens when {@code M} is created - * and its type is assigned, while the resolution in {@code L2} happens - * when the {@code invokevirtual} instruction is linked. - * <p> - * Apart from the checking of type descriptors, - * a method handle's capability to call its underlying method is unrestricted. - * If a method handle is formed on a non-public method by a class - * that has access to that method, the resulting handle can be used - * in any place by any caller who receives a reference to it. - * <p> - * Unlike with the Core Reflection API, where access is checked every time - * a reflective method is invoked, - * method handle access checking is performed - * <a href="MethodHandles.Lookup.html#access">when the method handle is created</a>. - * In the case of {@code ldc} (see below), access checking is performed as part of linking - * the constant pool entry underlying the constant method handle. - * <p> - * Thus, handles to non-public methods, or to methods in non-public classes, - * should generally be kept secret. - * They should not be passed to untrusted code unless their use from - * the untrusted code would be harmless. - * - * <h1>Method handle creation</h1> - * Java code can create a method handle that directly accesses - * any method, constructor, or field that is accessible to that code. - * This is done via a reflective, capability-based API called - * {@link java.lang.invoke.MethodHandles.Lookup MethodHandles.Lookup} - * For example, a static method handle can be obtained - * from {@link java.lang.invoke.MethodHandles.Lookup#findStatic Lookup.findStatic}. - * There are also conversion methods from Core Reflection API objects, - * such as {@link java.lang.invoke.MethodHandles.Lookup#unreflect Lookup.unreflect}. - * <p> - * Like classes and strings, method handles that correspond to accessible - * fields, methods, and constructors can also be represented directly - * in a class file's constant pool as constants to be loaded by {@code ldc} bytecodes. - * A new type of constant pool entry, {@code CONSTANT_MethodHandle}, - * refers directly to an associated {@code CONSTANT_Methodref}, - * {@code CONSTANT_InterfaceMethodref}, or {@code CONSTANT_Fieldref} - * constant pool entry. - * (For full details on method handle constants, - * see sections 4.4.8 and 5.4.3.5 of the Java Virtual Machine Specification.) - * <p> - * Method handles produced by lookups or constant loads from methods or - * constructors with the variable arity modifier bit ({@code 0x0080}) - * have a corresponding variable arity, as if they were defined with - * the help of {@link #asVarargsCollector asVarargsCollector}. - * <p> - * A method reference may refer either to a static or non-static method. - * In the non-static case, the method handle type includes an explicit - * receiver argument, prepended before any other arguments. - * In the method handle's type, the initial receiver argument is typed - * according to the class under which the method was initially requested. - * (E.g., if a non-static method handle is obtained via {@code ldc}, - * the type of the receiver is the class named in the constant pool entry.) - * <p> - * Method handle constants are subject to the same link-time access checks - * their corresponding bytecode instructions, and the {@code ldc} instruction - * will throw corresponding linkage errors if the bytecode behaviors would - * throw such errors. - * <p> - * As a corollary of this, access to protected members is restricted - * to receivers only of the accessing class, or one of its subclasses, - * and the accessing class must in turn be a subclass (or package sibling) - * of the protected member's defining class. - * If a method reference refers to a protected non-static method or field - * of a class outside the current package, the receiver argument will - * be narrowed to the type of the accessing class. - * <p> - * When a method handle to a virtual method is invoked, the method is - * always looked up in the receiver (that is, the first argument). - * <p> - * A non-virtual method handle to a specific virtual method implementation - * can also be created. These do not perform virtual lookup based on - * receiver type. Such a method handle simulates the effect of - * an {@code invokespecial} instruction to the same method. - * - * <h1>Usage examples</h1> - * Here are some examples of usage: - * <blockquote><pre>{@code -Object x, y; String s; int i; -MethodType mt; MethodHandle mh; -MethodHandles.Lookup lookup = MethodHandles.lookup(); -// mt is (char,char)String -mt = MethodType.methodType(String.class, char.class, char.class); -mh = lookup.findVirtual(String.class, "replace", mt); -s = (String) mh.invokeExact("daddy",'d','n'); -// invokeExact(Ljava/lang/String;CC)Ljava/lang/String; -assertEquals(s, "nanny"); -// weakly typed invocation (using MHs.invoke) -s = (String) mh.invokeWithArguments("sappy", 'p', 'v'); -assertEquals(s, "savvy"); -// mt is (Object[])List -mt = MethodType.methodType(java.util.List.class, Object[].class); -mh = lookup.findStatic(java.util.Arrays.class, "asList", mt); -assert(mh.isVarargsCollector()); -x = mh.invoke("one", "two"); -// invoke(Ljava/lang/String;Ljava/lang/String;)Ljava/lang/Object; -assertEquals(x, java.util.Arrays.asList("one","two")); -// mt is (Object,Object,Object)Object -mt = MethodType.genericMethodType(3); -mh = mh.asType(mt); -x = mh.invokeExact((Object)1, (Object)2, (Object)3); -// invokeExact(Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;)Ljava/lang/Object; -assertEquals(x, java.util.Arrays.asList(1,2,3)); -// mt is ()int -mt = MethodType.methodType(int.class); -mh = lookup.findVirtual(java.util.List.class, "size", mt); -i = (int) mh.invokeExact(java.util.Arrays.asList(1,2,3)); -// invokeExact(Ljava/util/List;)I -assert(i == 3); -mt = MethodType.methodType(void.class, String.class); -mh = lookup.findVirtual(java.io.PrintStream.class, "println", mt); -mh.invokeExact(System.out, "Hello, world."); -// invokeExact(Ljava/io/PrintStream;Ljava/lang/String;)V - * }</pre></blockquote> - * Each of the above calls to {@code invokeExact} or plain {@code invoke} - * generates a single invokevirtual instruction with - * the symbolic type descriptor indicated in the following comment. - * In these examples, the helper method {@code assertEquals} is assumed to - * be a method which calls {@link java.util.Objects#equals(Object,Object) Objects.equals} - * on its arguments, and asserts that the result is true. - * - * <h1>Exceptions</h1> - * The methods {@code invokeExact} and {@code invoke} are declared - * to throw {@link java.lang.Throwable Throwable}, - * which is to say that there is no static restriction on what a method handle - * can throw. Since the JVM does not distinguish between checked - * and unchecked exceptions (other than by their class, of course), - * there is no particular effect on bytecode shape from ascribing - * checked exceptions to method handle invocations. But in Java source - * code, methods which perform method handle calls must either explicitly - * throw {@code Throwable}, or else must catch all - * throwables locally, rethrowing only those which are legal in the context, - * and wrapping ones which are illegal. - * - * <h1><a name="sigpoly"></a>Signature polymorphism</h1> - * The unusual compilation and linkage behavior of - * {@code invokeExact} and plain {@code invoke} - * is referenced by the term <em>signature polymorphism</em>. - * As defined in the Java Language Specification, - * a signature polymorphic method is one which can operate with - * any of a wide range of call signatures and return types. - * <p> - * In source code, a call to a signature polymorphic method will - * compile, regardless of the requested symbolic type descriptor. - * As usual, the Java compiler emits an {@code invokevirtual} - * instruction with the given symbolic type descriptor against the named method. - * The unusual part is that the symbolic type descriptor is derived from - * the actual argument and return types, not from the method declaration. - * <p> - * When the JVM processes bytecode containing signature polymorphic calls, - * it will successfully link any such call, regardless of its symbolic type descriptor. - * (In order to retain type safety, the JVM will guard such calls with suitable - * dynamic type checks, as described elsewhere.) - * <p> - * Bytecode generators, including the compiler back end, are required to emit - * untransformed symbolic type descriptors for these methods. - * Tools which determine symbolic linkage are required to accept such - * untransformed descriptors, without reporting linkage errors. - * - * <h1>Interoperation between method handles and the Core Reflection API</h1> - * Using factory methods in the {@link java.lang.invoke.MethodHandles.Lookup Lookup} API, - * any class member represented by a Core Reflection API object - * can be converted to a behaviorally equivalent method handle. - * For example, a reflective {@link java.lang.reflect.Method Method} can - * be converted to a method handle using - * {@link java.lang.invoke.MethodHandles.Lookup#unreflect Lookup.unreflect}. - * The resulting method handles generally provide more direct and efficient - * access to the underlying class members. - * <p> - * As a special case, - * when the Core Reflection API is used to view the signature polymorphic - * methods {@code invokeExact} or plain {@code invoke} in this class, - * they appear as ordinary non-polymorphic methods. - * Their reflective appearance, as viewed by - * {@link java.lang.Class#getDeclaredMethod Class.getDeclaredMethod}, - * is unaffected by their special status in this API. - * For example, {@link java.lang.reflect.Method#getModifiers Method.getModifiers} - * will report exactly those modifier bits required for any similarly - * declared method, including in this case {@code native} and {@code varargs} bits. - * <p> - * As with any reflected method, these methods (when reflected) may be - * invoked via {@link java.lang.reflect.Method#invoke java.lang.reflect.Method.invoke}. - * However, such reflective calls do not result in method handle invocations. - * Such a call, if passed the required argument - * (a single one, of type {@code Object[]}), will ignore the argument and - * will throw an {@code UnsupportedOperationException}. - * <p> - * Since {@code invokevirtual} instructions can natively - * invoke method handles under any symbolic type descriptor, this reflective view conflicts - * with the normal presentation of these methods via bytecodes. - * Thus, these two native methods, when reflectively viewed by - * {@code Class.getDeclaredMethod}, may be regarded as placeholders only. - * <p> - * In order to obtain an invoker method for a particular type descriptor, - * use {@link java.lang.invoke.MethodHandles#exactInvoker MethodHandles.exactInvoker}, - * or {@link java.lang.invoke.MethodHandles#invoker MethodHandles.invoker}. - * The {@link java.lang.invoke.MethodHandles.Lookup#findVirtual Lookup.findVirtual} - * API is also able to return a method handle - * to call {@code invokeExact} or plain {@code invoke}, - * for any specified type descriptor . - * - * <h1>Interoperation between method handles and Java generics</h1> - * A method handle can be obtained on a method, constructor, or field - * which is declared with Java generic types. - * As with the Core Reflection API, the type of the method handle - * will constructed from the erasure of the source-level type. - * When a method handle is invoked, the types of its arguments - * or the return value cast type may be generic types or type instances. - * If this occurs, the compiler will replace those - * types by their erasures when it constructs the symbolic type descriptor - * for the {@code invokevirtual} instruction. - * <p> - * Method handles do not represent - * their function-like types in terms of Java parameterized (generic) types, - * because there are three mismatches between function-like types and parameterized - * Java types. - * <ul> - * <li>Method types range over all possible arities, - * from no arguments to up to the <a href="MethodHandle.html#maxarity">maximum number</a> of allowed arguments. - * Generics are not variadic, and so cannot represent this.</li> - * <li>Method types can specify arguments of primitive types, - * which Java generic types cannot range over.</li> - * <li>Higher order functions over method handles (combinators) are - * often generic across a wide range of function types, including - * those of multiple arities. It is impossible to represent such - * genericity with a Java type parameter.</li> - * </ul> - * - * <h1><a name="maxarity"></a>Arity limits</h1> - * The JVM imposes on all methods and constructors of any kind an absolute - * limit of 255 stacked arguments. This limit can appear more restrictive - * in certain cases: - * <ul> - * <li>A {@code long} or {@code double} argument counts (for purposes of arity limits) as two argument slots. - * <li>A non-static method consumes an extra argument for the object on which the method is called. - * <li>A constructor consumes an extra argument for the object which is being constructed. - * <li>Since a method handle’s {@code invoke} method (or other signature-polymorphic method) is non-virtual, - * it consumes an extra argument for the method handle itself, in addition to any non-virtual receiver object. - * </ul> - * These limits imply that certain method handles cannot be created, solely because of the JVM limit on stacked arguments. - * For example, if a static JVM method accepts exactly 255 arguments, a method handle cannot be created for it. - * Attempts to create method handles with impossible method types lead to an {@link IllegalArgumentException}. - * In particular, a method handle’s type must not have an arity of the exact maximum 255. - * - * @see MethodType - * @see MethodHandles - * @author John Rose, JSR 292 EG - */ public abstract class MethodHandle { - // Android-changed: - // - // static { MethodHandleImpl.initStatics(); } - // - // LambdaForm and customizationCount are currently unused in our implementation - // and will be substituted with appropriate implementation / delegate classes. - // - // /*private*/ final LambdaForm form; - // form is not private so that invokers can easily fetch it - // /*non-public*/ byte customizationCount; - // customizationCount should be accessible from invokers - - - /** - * Internal marker interface which distinguishes (to the Java compiler) - * those methods which are <a href="MethodHandle.html#sigpoly">signature polymorphic</a>. - * - * @hide - */ - @java.lang.annotation.Target({java.lang.annotation.ElementType.METHOD}) - @java.lang.annotation.Retention(java.lang.annotation.RetentionPolicy.RUNTIME) - public @interface PolymorphicSignature { } - - /** - * The type of this method handle, this corresponds to the exact type of the method - * being invoked. - */ - private final MethodType type; - - /** - * The nominal type of this method handle, will be non-null if a method handle declares - * a different type from its "real" type, which is either the type of the method being invoked - * or the type of the emulated stackframe expected by an underyling adapter. - */ - private MethodType nominalType; - - /** - * The spread invoker associated with this type with zero trailing arguments. - * This is used to speed up invokeWithArguments. - */ - private MethodHandle cachedSpreadInvoker; - - /** - * The INVOKE* constants and SGET/SPUT and IGET/IPUT constants specify the behaviour of this - * method handle with respect to the ArtField* or the ArtMethod* that it operates on.

* Java expression or bytecoded constant. - * <li>Likewise, if {@code T} or {@code MT} - * is not symbolically accessible from the lookup class's loader, - * the lookup can still succeed. - * For example, lookups for {@code MethodHandle.invokeExact} and - * {@code MethodHandle.invoke} will always succeed, regardless of requested type. - * <li>If there is a security manager installed, it can forbid the lookup - * on various grounds (<a href="MethodHandles.Lookup.html#secmgr">see below</a>). - * By contrast, the {@code ldc} instruction on a {@code CONSTANT_MethodHandle} - * constant is not subject to security manager checks. - * <li>If the looked-up method has a - * <a href="MethodHandle.html#maxarity">very large arity</a>, - * the method handle creation may fail, due to the method handle - * type having too many parameters. - * </ul> - * - * <h1><a name="access"></a>Access checking</h1> - * Access checks are applied in the factory methods of {@code Lookup}, - * when a method handle is created. - * This is a key difference from the Core Reflection API, since - * {@link java.lang.reflect.Method#invoke java.lang.reflect.Method.invoke} - * performs access checking against every caller, on every call. - * <p> - * All access checks start from a {@code Lookup} object, which - * compares its recorded lookup class against all requests to - * create method handles. - * A single {@code Lookup} object can be used to create any number - * of access-checked method handles, all checked against a single - * lookup class. - * <p> - * A {@code Lookup} object can be shared with other trusted code, - * such as a metaobject protocol. - * A shared {@code Lookup} object delegates the capability - * to create method handles on private members of the lookup class. - * Even if privileged code uses the {@code Lookup} object, - * the access checking is confined to the privileges of the - * original lookup class. - * <p> - * A lookup can fail, because - * the containing class is not accessible to the lookup class, or - * because the desired class member is missing, or because the - * desired class member is not accessible to the lookup class, or - * because the lookup object is not trusted enough to access the member. - * In any of these cases, a {@code ReflectiveOperationException} will be - * thrown from the attempted lookup. The exact class will be one of - * the following: - * <ul> - * <li>NoSuchMethodException — if a method is requested but does not exist - * <li>NoSuchFieldException — if a field is requested but does not exist - * <li>IllegalAccessException — if the member exists but an access check fails - * </ul> - * <p> - * In general, the conditions under which a method handle may be - * looked up for a method {@code M} are no more restrictive than the conditions - * under which the lookup class could have compiled, verified, and resolved a call to {@code M}. - * Where the JVM would raise exceptions like {@code NoSuchMethodError}, - * a method handle lookup will generally raise a corresponding - * checked exception, such as {@code NoSuchMethodException}. - * And the effect of invoking the method handle resulting from the lookup - * is <a href="MethodHandles.Lookup.html#equiv">exactly equivalent</a> - * to executing the compiled, verified, and resolved call to {@code M}. - * The same point is true of fields and constructors. - * <p style="font-size:smaller;"> - * <em>Discussion:</em> - * Access checks only apply to named and reflected methods, - * constructors, and fields. - * Other method handle creation methods, such as - * {@link MethodHandle#asType MethodHandle.asType}, - * do not require any access checks, and are used - * independently of any {@code Lookup} object. - * <p> - * If the desired member is {@code protected}, the usual JVM rules apply, - * including the requirement that the lookup class must be either be in the - * same package as the desired member, or must inherit that member. - * (See the Java Virtual Machine Specification, sections 4.9.2, 5.4.3.5, and 6.4.) - * In addition, if the desired member is a non-static field or method - * in a different package, the resulting method handle may only be applied - * to objects of the lookup class or one of its subclasses. - * This requirement is enforced by narrowing the type of the leading - * {@code this} parameter from {@code C} - * (which will necessarily be a superclass of the lookup class) - * to the lookup class itself. - * <p> - * The JVM imposes a similar requirement on {@code invokespecial} instruction, - * that the receiver argument must match both the resolved method <em>and</em> - * the current class. Again, this requirement is enforced by narrowing the - * type of the leading parameter to the resulting method handle. - * (See the Java Virtual Machine Specification, section 4.10.1.9.) - * <p> - * The JVM represents constructors and static initializer blocks as internal methods - * with special names ({@code "<init>"} and {@code "<clinit>"}). - * The internal syntax of invocation instructions allows them to refer to such internal - * methods as if they were normal methods, but the JVM bytecode verifier rejects them. - * A lookup of such an internal method will produce a {@code NoSuchMethodException}. - * <p> - * In some cases, access between nested classes is obtained by the Java compiler by creating - * an wrapper method to access a private method of another class - * in the same top-level declaration. - * For example, a nested class {@code C.D} - * can access private members within other related classes such as - * {@code C}, {@code C.D.E}, or {@code C.B}, - * but the Java compiler may need to generate wrapper methods in - * those related classes. In such cases, a {@code Lookup} object on - * {@code C.E} would be unable to those private members. - * A workaround for this limitation is the {@link Lookup#in Lookup.in} method, - * which can transform a lookup on {@code C.E} into one on any of those other - * classes, without special elevation of privilege. - * <p> - * The accesses permitted to a given lookup object may be limited, - * according to its set of {@link #lookupModes lookupModes}, - * to a subset of members normally accessible to the lookup class. - * For example, the {@link #publicLookup publicLookup} - * method produces a lookup object which is only allowed to access - * public members in public classes. - * The caller sensitive method {@link #lookup lookup} - * produces a lookup object with full capabilities relative to - * its caller class, to emulate all supported bytecode behaviors. - * Also, the {@link Lookup#in Lookup.in} method may produce a lookup object - * with fewer access modes than the original lookup object. - * - * <p style="font-size:smaller;"> - * <a name="privacc"></a> - * <em>Discussion of private access:</em> - * We say that a lookup has <em>private access</em> - * if its {@linkplain #lookupModes lookup modes} - * include the possibility of accessing {@code private} members. - * As documented in the relevant methods elsewhere, - * only lookups with private access possess the following capabilities: - * <ul style="font-size:smaller;"> - * <li>access private fields, methods, and constructors of the lookup class - * <li>create method handles which invoke <a href="MethodHandles.Lookup.html#callsens">caller sensitive</a> methods, - * such as {@code Class.forName} - * <li>create method handles which {@link Lookup#findSpecial emulate invokespecial} instructions - * <li>avoid <a href="MethodHandles.Lookup.html#secmgr">package access checks</a> - * for classes accessible to the lookup class - * <li>create {@link Lookup#in delegated lookup objects} which have private access to other classes - * within the same package member - * </ul> - * <p style="font-size:smaller;"> - * Each of these permissions is a consequence of the fact that a lookup object - * with private access can be securely traced back to an originating class, - * whose <a href="MethodHandles.Lookup.html#equiv">bytecode behaviors</a> and Java language access permissions - * can be reliably determined and emulated by method handles. - * - * <h1><a name="secmgr"></a>Security manager interactions</h1> - * Although bytecode instructions can only refer to classes in - * a related class loader, this API can search for methods in any - * class, as long as a reference to its {@code Class} object is - * available. Such cross-loader references are also possible with the - * Core Reflection API, and are impossible to bytecode instructions - * such as {@code invokestatic} or {@code getfield}. - * There is a {@linkplain java.lang.SecurityManager security manager API} - * to allow applications to check such cross-loader references. - * These checks apply to both the {@code MethodHandles.Lookup} API - * and the Core Reflection API - * (as found on {@link java.lang.Class Class}). - * <p> - * If a security manager is present, member lookups are subject to - * additional checks. - * From one to three calls are made to the security manager. - * Any of these calls can refuse access by throwing a - * {@link java.lang.SecurityException SecurityException}. - * Define {@code smgr} as the security manager, - * {@code lookc} as the lookup class of the current lookup object, - * {@code refc} as the containing class in which the member - * is being sought, and {@code defc} as the class in which the - * member is actually defined. - * The value {@code lookc} is defined as <em>not present</em> - * if the current lookup object does not have - * <a href="MethodHandles.Lookup.html#privacc">private access</a>. - * The calls are made according to the following rules: - * <ul> - * <li><b>Step 1:</b> - * If {@code lookc} is not present, or if its class loader is not - * the same as or an ancestor of the class loader of {@code refc}, - * then {@link SecurityManager#checkPackageAccess - * smgr.checkPackageAccess(refcPkg)} is called, - * where {@code refcPkg} is the package of {@code refc}. - * <li><b>Step 2:</b> - * If the retrieved member is not public and - * {@code lookc} is not present, then - * {@link SecurityManager#checkPermission smgr.checkPermission} - * with {@code RuntimePermission("accessDeclaredMembers")} is called. - * <li><b>Step 3:</b> - * If the retrieved member is not public, - * and if {@code lookc} is not present, - * and if {@code defc} and {@code refc} are different, - * then {@link SecurityManager#checkPackageAccess - * smgr.checkPackageAccess(defcPkg)} is called, - * where {@code defcPkg} is the package of {@code defc}. - * </ul> - * Security checks are performed after other access checks have passed. - * Therefore, the above rules presuppose a member that is public, - * or else that is being accessed from a lookup class that has - * rights to access the member. - * - * <h1><a name="callsens"></a>Caller sensitive methods</h1> - * A small number of Java methods have a special property called caller sensitivity. - * A <em>caller-sensitive</em> method can behave differently depending on the - * identity of its immediate caller. - * <p> - * If a method handle for a caller-sensitive method is requested, - * the general rules for <a href="MethodHandles.Lookup.html#equiv">bytecode behaviors</a> apply, - * but they take account of the lookup class in a special way. - * The resulting method handle behaves as if it were called - * from an instruction contained in the lookup class, - * so that the caller-sensitive method detects the lookup class. - * (By contrast, the invoker of the method handle is disregarded.) - * Thus, in the case of caller-sensitive methods, - * different lookup classes may give rise to - * differently behaving method handles. - * <p> - * In cases where the lookup object is - * {@link #publicLookup publicLookup()}, - * or some other lookup object without - * <a href="MethodHandles.Lookup.html#privacc">private access</a>, - * the lookup class is disregarded. - * In such cases, no caller-sensitive method handle can be created, - * access is forbidden, and the lookup fails with an - * {@code IllegalAccessException}. - * <p style="font-size:smaller;"> - * <em>Discussion:</em> - * For example, the caller-sensitive method - * {@link java.lang.Class#forName(String) Class.forName(x)} - * can return varying classes or throw varying exceptions, - * depending on the class loader of the class that calls it. - * A public lookup of {@code Class.forName} will fail, because - * there is no reasonable way to determine its bytecode behavior. - * <p style="font-size:smaller;"> - * If an application caches method handles for broad sharing, - * it should use {@code publicLookup()} to create them. - * If there is a lookup of {@code Class.forName}, it will fail, - * and the application must take appropriate action in that case. - * It may be that a later lookup, perhaps during the invocation of a - * bootstrap method, can incorporate the specific identity - * of the caller, making the method accessible. - * <p style="font-size:smaller;"> - * The function {@code MethodHandles.lookup} is caller sensitive -
