org.jxbeans.flow_control
Class Decision  

java.lang.Object
  org.jxbeans.AbstractJXBean
      org.jxbeans.AbstractDocumentSource
          org.jxbeans.flow_control.Decision

All Implemented Interfaces:

org.jxbeans.DocumentReadyListener, org.jxbeans.DocumentSource, java.util.EventListener, java.io.Serializable

---

public class Decision

extends org.jxbeans.AbstractDocumentSource

implements org.jxbeans.DocumentReadyListener

The Decision JXBean represents an "if" condition in a JXBean model. If the XPath expression property evaluates to true, the a DocumentReadyEvent will be sent to the standard DocumentReadyListeners. If the XPath expression evaluates to false, a DocumentReadyEvent will be sent to the "false" DocumentReadyListener.
