Class MethodProxyTransformation

java.lang.Object
  org.sourceforge.jemm.weaver.transformation.AbstractClassTransformation
      org.sourceforge.jemm.weaver.transformation.MethodProxyTransformation

All Implemented Interfaces:

Transformation

public class MethodProxyTransformation
extends AbstractClassTransformation

Proxies all methods a begin and end call. Also detects synchronisation and adds in calls for begin and end Lock. beginLock and endLock calls are only present if the method was declared synchronised. Produces code similar to: jemmLCL.beginMethod(this); jemmLVL.beginLock(this); try { //original code } finally { jemmLVL.endLock(this); jemmLCL.endMethod(this); }
