[e4-dev] DI TypedBinding's Implementation

[Joseph D Carroll Jr <jdsalingerjr@xxxxxxxxx>]

I just released an enhancement for the DI engine that allows for the creation of (what I am calling) typed bindings:

http://bugs.eclipse.org/bugs/show_bug.cgi?id=389634

Here is an example of what you are able to do with typed bindings:

injector.addTypedBinding(String.class).toInstance("My string");

injector.addTypedBinding(String.class).named("NAMED").toInstance("Some other string");

injector.addTypedBinding(FooBar.class).annotatedWith(MyAnnotation.class).toInstance(myFooBarImpl);

injector.addTypedBinding(FooBar.class).named("NAMED").annotatedWith(ExecuteMe.class).toInstance(someOtherFooBarImpl);

injector.addTypedBinding(FooBar.class).annotatedWith(MyOtherAnnotation.class).named("NAMED").toImplementation(FooBar.class);

injector.addTypedBinding(TestSingleton.class);

I am certainly open to, and looking for, comments and will continue to make enhancements and any fixes.  In the next few days I will put together a little better documentation.

This implementation is also 100% backwards compatible with the current bindings.
