Class Proxy<T>

  • Type Parameters:
    T - the type managed by this Proxy
    public class Proxy<T>
extends 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.
