Class CflowBinding

java.lang.Object
  org.codehaus.aspectwerkz.cflow.CflowBinding

public class CflowBinding
extends Object

A Cflow binding represents an extracted cflow or cflowbelow subexpression

For a given pointcut "pcA and cflowA or cflowbelowB", we will extract two bindings. The m_cflowID must be unique on a per cflow sub expresion basis ie JVM wide.

Note: CflowBinding hashcode depends on Cflow_ID (sub expr) + isCflowBelow only.
