Class BoundVariableEvaluationContext

java.lang.Object
  org.apache.ode.bpel.rtrep.v2.BoundVariableEvaluationContext

All Implemented Interfaces:

EvaluationContext

public class BoundVariableEvaluationContext
extends java.lang.Object
implements EvaluationContext

Expression language evaluation context used for expressions referencing a predefined variable bound to a given value. Used for correlation matching based on a message value extraction function (i.e. SimPEL+JS).
