Examples of com.google.inject.Injector

com.google.inject.Injector
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} 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.
The {@code Injector} API has a few additional features: it allowspre-constructed instances to have their fields and methods injected and offers programmatic introspection to support tool development.
Contains several default bindings:
- This {@link Injector} instance itself
- A {@code Provider} for each binding of type {@code T}
- The {@link java.util.logging.Logger} for the class being injected
- The {@link Stage} in which the Injector was created
Injectors are created using the facade class {@link Guice}. @author crazybob@google.com (Bob Lee)
