Class Proxy<T>

java.lang.Object

ej.kf.Proxy<T>

Type Parameters:

T - the type managed by this Proxy

public class Proxy<T>
extends java.lang.Object

The superclass of proxy classes. A proxy class is a class that directly extends this class and directly implements a shared interface. Each method of the implemented interface must be defined according to the following pattern:

 public class MyProxy extends Proxy<MySharedInterface> implements MySharedInterface{
        public void foo(){
                try{
                        invoke();
                }
                catch(Throwable e){
                        // return or throw default case (deny of service)
                }
        }
 

A Proxy instance has a link to a reference owned by another Feature. The reference may be automatically removed by the garbage collector.
