public final class MethodName extends java.lang.Object
Understands the name of a method to invoke using Java Reflection.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
(); // Equivalent to call 'jedi.getPowers()' List<String> powers =method
("getPowers").withReturnType
(newTypeRef
<List<String>>() {}) .in
(person) .invoke
