Guice provides a means to find all bindings for a given type (Injector#findBindingsByType) and it also provides a TypeLiteral class from which it seems possible to construct a wildcard type. What I would like to do is find all bindings for some type that is parameterised by a wildcard type but I can't figure out how to do it. A look at the guice src suggests I might be barking up the wrong tree but I figured I'd ask around anyway... so for example given a type
Foo<E extends Bar>
BarImplOne implements Bar
BarImplTwo implements Bar
and some bindings like
bind(new TypeLiteral<Foo<BarImplOne>>() {}).to(MyFooOne.class);
bind(new TypeLiteral<Foo<BarImplTwo>>() {}).to(MyFooTwo.class);
then I want to be able to discover both bindings with something like
Injector.findBindingsByType(TypeLiteral.get(Types.newParameterizedType(Foo.class, Types.subtypeOf(Bar.class))));
Any ideas?
