  +--org.smartcomps.twister.engine.priv.expression.impl.BPELExpressionProcessorImpl

All Implemented Interfaces:

ExpressionProcessor

public class BPELExpressionProcessorImpl

extends java.lang.Object

implements ExpressionProcessor

Implementation of the ExpressionProcessor interface that evaluates BPEL expressions. Those expressions follow the XPath grammar with the additions of BPEL functions.
