Class DelegateMethodAction

java.lang.Object
  com.iternum.swlink.action.AbstractAction
      com.iternum.swlink.action.DelegateMethodAction

All Implemented Interfaces:

Action

public class DelegateMethodAction

extends AbstractAction

A Action that invokes a delegate method on the target. This action supports four ways to define a delegate method

1. A delegate with no parameters TargetClass.delegateMethod()
2. A delegate that gets the source passed as an argument TargetClass.delegateMethod(Object pSource)
3. A delegate that gets the extraArgs passed as an argument TargetClass.delegateMethod(Object pExtraArgs)
4. A delegate that gets both the source and the extraArgs passed as an argument TargetClass.delegateMethod(Object pSource, Object pExtraArgs)
Since the signatures of the methods are resolved at runtime, this Action may call any method whose parameters are assignable from the actual runtime parameters.
