Class ConstructorCallVisitor.ReplaceNewInstructionCodeAdapter

java.lang.Object
  org.objectweb.asm.CodeAdapter
      org.codehaus.aspectwerkz.transform.inlining.weaver.ConstructorCallVisitor.ReplaceNewInstructionCodeAdapter

All Implemented Interfaces:

org.objectweb.asm.CodeVisitor

Enclosing class:

ConstructorCallVisitor

public class ConstructorCallVisitor.ReplaceNewInstructionCodeAdapter
extends org.objectweb.asm.CodeAdapter

Replaces 'new' instructions with a call to the compiled JoinPoint instance.
It does the following: - remove NEW when we know (from first visit) that it matchs - remove DUP that follows NEW - replace INVOKESPECIAL with call to JP
