Class ListenerMethodInvokerImpl

java.lang.Object

org.apache.tapestry.listener.ListenerMethodInvokerImpl

All Implemented Interfaces:

ListenerMethodInvoker

public class ListenerMethodInvokerImpl
extends java.lang.Object
implements ListenerMethodInvoker

Logic for mapping a listener method name to an actual method invocation; this may require a little searching to find the correct version of the method, based on the number of parameters to the method (there's a lot of flexibility in terms of what methods may be considered a listener method).

Since:

4.0
