Class Property

java.lang.Object

public class Property
extends Object

This class has nested resources that can be used to produce callback-values for Property.Callback through annotations.

Example usage ...

 @RunWith(CallbackParamsRunner)
 public class MyTest {

   @Test
   public void runTest(Property.Callback<MyBean> beanCallback) {
     // ...
   }

   @Property.BeanClass(MyBean.class)
   @Property.Name("myIntProperty")
   enum MyEnum {
       @Property.Value("21") FOO,
       @Property.Value("67") BAR;
   }
 }
 

The annotations around and within MyEnum are meant as a shortcut that is equivalent with this ...

   enum MyEnum implements Property.Callback<MyBean> {
     FOO(21), BAR(67);

     int value;

     MyEnum(int value) {
       this.value = value;
     }

     void setValues(MyBean bean) {
         bean.setMyIntProperty(value);
     }

     void assertValues(MyBean bean) {
       Assert.assertEquals("Value for property \"myIntProperty\" on " + bean,
           value, bean.getMyIntProperty());
     }
   }
 

Thus, a considerable amount of (bold) boilerplate code can be excluded by using the annotations, as shown in the first case.

This class is meant as a proof-of-concept for the Wrapping API that can be used to specify an implementation of a callback-interface from a callback-value that neither implements the callback-interface nor provides any implementation through CallbackFactory.getCallback().
This class being a proof-of-concept means that it applies to a concept that is generally understood among developers (i.e. beans and their properties) but unlike the other sandbox utility Collector the reusability of this class is probably more limited.
