Class FusionInvoker

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.reflect.InvocationHandler
    public class FusionInvoker
extends java.lang.Object
implements java.lang.reflect.InvocationHandler, java.io.Serializable
    The fusion invocation handler. It is used to fuse two or more instance into one object. It is usefully if you want to have a single object to represent two more other instances.

    Example: 

    
 public interface IA {
   public void f();
 }
 public interface IB {
   public void g();
 }
 public class A implements IA {
   public void f() {...}
 }
 public class B implements IB {
   public void g() {...}
 }
    Then, you could fuse them together as follows: 
    
 Object obj = FusionInvoker.newInstance(new Object[] {new A(), new B()});
    Thus, the fused proxy object, obj, could be used as if it implements IA and IB: 
    
  IA ia = (IA) obj;
  ia.f();
  IB ib = (IB) obj;
  ib.g();
