</PRE>

<P>
An API to bind multiple map entries separately, only to later inject them as
 a complete map. MapBinder is intended for use in your application's module:
 <pre><code>
 public class SnacksModule extends AbstractModule {
   protected void configure() {
     MapBinder&lt;String, Snack&gt; mapbinder
         = MapBinder.newMapBinder(binder(), String.class, Snack.class);
     mapbinder.addBinding("twix").toInstance(new Twix());
     mapbinder.addBinding("snickers").toProvider(SnickersProvider.class);
     mapbinder.addBinding("skittles").to(Skittles.class);
   }
 }</code></pre>

 <p>With this binding, a <A HREF="http://java.sun.com/javase/6/docs/api/java/util/Map.html" title="class or interface in java.util"><CODE>Map</CODE></A><code>&lt;String, Snack&gt;</code> can now be 
 injected:
 <pre><code>
 class SnackMachine {
   @Inject
   public SnackMachine(Map&lt;String, Snack&gt; snacks) { ... }
 }</code></pre>
 
 <p>In addition to binding <code>Map&lt;K, V&gt;</code>, a mapbinder will also bind
 <code>Map&lt;K, Provider&lt;V&gt;&gt;</code> for lazy value provision:
 <pre><code>
 class SnackMachine {
   @Inject
   public SnackMachine(Map&lt;String, Provider&lt;Snack&gt;&gt; snackProviders) { ... }
 }</code></pre>

 <p>Creating mapbindings from different modules is supported. For example, it
 is okay to have both <code>CandyModule</code> and <code>ChipsModule</code> both
 create their own <code>MapBinder&lt;String, Snack&gt;</code>, and to each contribute 
 bindings to the snacks map. When that map is injected, it will contain 
 entries from both modules.

 <p>Values are resolved at map injection time. If a value is bound to a
 provider, that provider's get method will be called each time the map is
 injected (unless the binding is also scoped).

 <p>Annotations are be used to create different maps of the same key/value
 type. Each distinct annotation gets its own independent map.

 <p><strong>Keys must be distinct.</strong> If the same key is bound more than
 once, map injection will fail.

 <p><strong>Keys must be non-null.</strong> <code>addBinding(null)</code> will 
 throw an unchecked exception.

 <p><strong>Values must be non-null to use map injection.</strong> If any
 value is null, map injection will fail (although injecting a map of providers
 will not).

<DL>
<DD>Returns a binding builder used to add a new entry in the map. Each
 key must be distinct (and non-null). Bound providers will be evaluated each
 time the map is injected.

 <p>It is an error to call this method without also calling one of the
 <code>to</code> methods on the returned binding builder.

 <p>Scoping elements independently is supported. Use the <code>in</code> method
 to specify a binding scope.
