Package edu.uiuc.ncsa.security.util.functor.parser.event

Class ConditionalHandler

java.lang.Object

edu.uiuc.ncsa.security.util.functor.parser.AbstractHandler

edu.uiuc.ncsa.security.util.functor.parser.event.ConditionalHandler

All Implemented Interfaces:

CommaListener, DelimiterListener, Serializable, EventListener

public class ConditionalHandler
extends AbstractHandler
implements DelimiterListener, CommaListener

This handles a logic block of the form if[A]then[B}else[C]. Each of if, then, else are conditionals and a stack of which is doing what is kept. The final result i the getLogicBlock() call that returns the whole thing.
If this is invoked and there is no conditional stack (so against a sinple functor) then the functor handler will have that in it and you can access it that way.
