          extended by org.objectweb.asm.commons.GeneratorAdapter
              extended by org.apache.felix.ipojo.manipulation.MethodCodeAdapter
All Implemented Interfaces:
org.objectweb.asm.MethodVisitor, org.objectweb.asm.Opcodes

public class MethodCodeAdapter
extends org.objectweb.asm.commons.GeneratorAdapter
implements org.objectweb.asm.Opcodes

Insert code calling callbacks at the entry and before the exit of a method. Moreover it replaces all GETFIELD and SETFIELD by getter and setter invocation.
