Package org.fest.reflect.method

Class StaticMethodReturnType<T>

java.lang.Object

org.fest.reflect.method.StaticMethodReturnType<T>

Type Parameters:

T - the generic type of the static method's return type.

public class StaticMethodReturnType<T>
extends Object

Understands the return type of the static method to invoke.

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

   // Equivalent to call 'Jedi.setCommonPower("Jump")'
   staticMethod("setCommonPower").withParameterTypes(String.class)
                                 .in(Jedi.class)
                                 .invoke("Jump");

   // Equivalent to call 'Jedi.addPadawan()'
   staticMethod("addPadawan").in(Jedi.class).invoke();

   // Equivalent to call 'Jedi.commonPowerCount()'
   String name = staticMethod("commonPowerCount").withReturnType(String.class)
                                                 .in(Jedi.class)
                                                 .invoke();

   // Equivalent to call 'Jedi.getCommonPowers()'
   List<String> powers = staticMethod("getCommonPowers").withReturnType(new TypeRef<List<String>>() {})
                                                        .in(Jedi.class)
                                                        .invoke();
