How can I inject a bounded-wildcard class?

Also posted on Stack Overflow.

Using Guice, I want to inject a bounded-wildcard class. To be clear, I don't want to inject an object, but inject a class type. I think the constructor should look something like this:

class A {
   class<?> a;
   @Inject A(TypeLiteral<Class<? extends SuperClass>> a) {
      this.a = a.getRawType();
   }
}

Is the above code is correct? How can I bind the TypeLiteral?

Thanks!

Thanks to MForster at Stack Overflow for his answer:

Guice doesn't allow binding TypeLiteral. But it's unclear why you would want to inject a TypeLiteral in the first place.

Maybe this is what you want:

class A {
  Class<? extends SuperClass> a;
  @Inject A(Class<? extends SuperClass> a) {
    this.a = a;
  }
}

together with this binding:

bind(new TypeLiteral<Class<? extends SuperClass>>() {})
    .toInstance(SubClass.class);
