Class MethodReturnType<T>

  • Type Parameters:
    T - the generic type of the method's return type.
    public class MethodReturnType<T>
extends java.lang.Object
    Understands the return type of the method to invoke.

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

       // Equivalent to call 'person.setName("Luke")'
   method("setName").withParameterTypes(String.class)
                    .in(person)
                    .invoke("Luke");

   // 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();
