Seems easier to create a TrueFooProvider and FalseFooProvider and bind
those to your annotations.
bind(Foo.class).annotatedWith(Names.named("TrueBar").toProvider(TrueFooProvider.class);
bind(Foo.class).annotatedWith(Names.named("FalseBar").toProvider(FalseFooProvider.class);
Or, I would refactor to something like, if it's a more dynamic state
set during initialization sequence:
bind(FooType.class).annotatedWith(Names.named("FooType").to(Boolean.class);
class Foo {
@Inject Named("FooType")
private final Boolean fooType;
.
.
.
}
Wonky little scenario but hope it helps.
