All Implemented Interfaces:

java.io.Serializable

public final class EvaluationVetoException
extends java.lang.Exception

This exception allows ExecutionListener implementations to veto the evaluation of the actual evaluation of the expression. To do this, they need to throw this exception in their preExecute method.
Vetoing the evaluation of an expression requires them to provide an object that is used as the result of the expression. This object is passed to the exception as the sole constructor parameter.
