public class DuckTypingInvoker
extends Object
implements Invoker

An invoker which supports "duck typing", meaning that it finds a matching method on the object returned from the target provider and invokes it. This class is useful for adapting an existing class to an interface it does not implement.

Example:

 public class LegacyDuck // Does not implement interface!
 {
   public void quack()
   {
     // Quacking logic...
   }
 }
 

 public interface Duck
 {
   public void quack();
 }
 

 ObjectProvider targetProvider = new ConstantProvider(new LegacyDuck()); // Always returns a "legacy" duck
 DuckTypingInvoker invoker = new DuckTypingInvoker(targetProvider);
 Duck duck = ( Duck )proxyFactory.createInvokerProxy( invoker, new Class[] { Duck.class } );
