Interface Injector</H2>
<HR>
<DL>
<DT><PRE>public interface <B>Injector</B></DL>
</PRE>
<P>
Builds the graphs of objects that make up your application. The injector tracks the dependencies
for each type and uses bindings to inject them. This is the core of Guice, although you rarely
interact with it directly. This "behind-the-scenes" operation is what distinguishes dependency
injection from its cousin, the service locator pattern.
<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<T></code> for each binding of type <code>T</code>
<li>The <A HREF="http://java.sun.com/j2se/1.5.0/docs/api/java/util/logging/Logger.html?is-external=true" 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>.
<p>An injector can also <A HREF="../../../com/google/inject/Injector.html#injectMembers(java.lang.Object)"><CODE>inject the dependencies</CODE></A> of
already-constructed instances. This can be used to interoperate with objects created by other
frameworks or services.
<p>Injectors can be <A HREF="../../../com/google/inject/Injector.html#createChildInjector(java.lang.Iterable)"><CODE>hierarchical</CODE></A>. Child injectors inherit
the configuration of their parent injectors, but the converse does not hold.
<p>The injector's <A HREF="../../../com/google/inject/Injector.html#getBindings()"><CODE>internal bindings</CODE></A> are available for introspection. This
enables tools and extensions to operate on an injector reflectively.
