 /**
 20  
  * An object, used by a {@link org.apache.tapestry.listener.ListenerMap}, to
 21  
  * match requests (possibly with service parameters) to methods (possibly with
 22  
  * arguments). Given a request, a (possibly null or empty) array of service
 23  
  * parameters, and a target object (and its set of public void methods), the
 24  
  * mapping will search for the mostly likely mapping. In order:
 25  
  * <ul>
 26  
  * <li>public void method(params) (where the method takes the same number of
 27  
  * parameters as there are service parameters)
 28  
  * <li>public void method(IRequestCycle, params)
 29  
  * <li>public void method()
 30  
  * <li>public void method(IRequestCycle)
 31  
  * </ul>
