Annotation Type DefaultImplementation

@Target(value=TYPE)
@Documented
@Retention(value=RUNTIME)
public @interface DefaultImplementation

Allows interfaces to specify a default implementation.

Note that the default can be overridden after the fact by explicitly binding a different implementation to the interface.

For "normal" injections of a given library, this reduces the amount of boilerplate configuration code needed, and also shrinks the Tang configuration objects that need to be passed around.
