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();
