Interface Injector</H2>

<DL>
<DT><PRE>public interface <B>Injector</B></DL>
</PRE>

<P>
Fulfills requests for the object instances that make up your application,
 always ensuring that these instances are properly injected before they are
 returned. The <code>Injector</code> is the heart of the Guice framework,
 although you don't typically interact with it directly very often. This
 "behind-the-scenes" operation is what distinguishes the dependency
 injection pattern from its cousin, service locator.

 <p>The <code>Injector</code> API has a few additional features: it allows
 pre-constructed instances to have their fields and methods injected and
 offers programmatic introspection to support tool development.

 <p>Contains several default bindings:

 <ul>
 <li>This <A HREF="../../../com/google/inject/Injector.html" title="interface in com.google.inject"><CODE>Injector</CODE></A> instance itself
 <li>A <code>Provider&lt;T&gt;</code> for each binding of type <code>T</code>
 <li>The <A HREF="http://java.sun.com/javase/6/docs/api/java/util/logging/Logger.html" title="class or interface in java.util.logging"><CODE>Logger</CODE></A> for the class being injected
 <li>The <A HREF="../../../com/google/inject/Stage.html" title="enum in com.google.inject"><CODE>Stage</CODE></A> in which the Injector was created
 </ul>

 Injectors are created using the facade class <A HREF="../../../com/google/inject/Guice.html" title="class in com.google.inject"><CODE>Guice</CODE></A>.
