Type Parameters:
T - the generic type of the method's return type.

Understands the return type of the method to invoke.

The following is an example of proper usage of this class:

   // Equivalent to call 'person.concentrate()'
   method("concentrate").in(person).invoke();

   // Equivalent to call 'person.getName()'
   String name = method("getName").withReturnType(String.class)
                                  .in(person)
                                  .invoke();
