Comment #5 on issue 809 by sberlin: Guice Assisted Inject with multiple
implementations of interface
http://code.google.com/p/google-guice/issues/detail?id=809
Correct, (1) turns the original factory into a delegate and the shim is the
real factory (delegating to the delegate). The delegate's really just an
implementation detail, though, and the interface could be package-private,
etc.
(2) would be done with something like:
interface Factory {
@Named("BC") A create(int foo, int bar);
@Named("D") A create();
}
Module extends PrivateModule {
@Override public void configure() {
install(new FactoryModuleBuilder()
implement(Key.get(A.class, Names.named("BC"), targetBCClazz)
implement(Key.get(A.class, Names.named("D"), targetDClazz)
build(AFactory.class));
// + bind to named type, expose
}
}
install(getAFactoryModule("B", B.class, D.class));
install(getAFactoryModule("C", C.class, D.class));
