Interface Ginjector

public interface Ginjector

Where the GWT world stops and the GIN/Guice world begins. Analogous to Guice's Injector, this type can be used to bootstrap injection. Unlike Guice, however, this is not a type that you create, but rather a type that you extend. It's best explained with an example. Consider this Guice code:

 // Define and create a Module
 Module applicationModule = ...;
 
 // create an Injector
 Injector injector = Guice.createInjector(applicationModule);

 // bootstrap the injection
 injector.getInstance(Application.class);
 

Here's the equivalent GIN code:

 // Define a GinModule (e.g. ApplicationModule) but don't create it.

 // create a Ginjector
 ApplicationGinjector ginjector = GWT.create(ApplicationGinjector.class);
 
 // bootstrap the injection
 RootPanel.get().add(ginjector.getApplication());

 (somewhere else...)

 // define a Ginjector subtype
 @GinModules(ApplicationModule.class)
 public interface ApplicationGinjector extends Ginjector {
   Application getApplication();
 }
 

Note that this is not named "G-injector" -- its "GIN-jector."
