Class AdviceAdapter

java.lang.Object
  org.objectweb.asm.MethodAdapter
      org.objectweb.asm.commons.LocalVariablesSorter
          org.objectweb.asm.commons.GeneratorAdapter
              org.objectweb.asm.commons.AdviceAdapter

All Implemented Interfaces:: MethodVisitor, Opcodes

public abstract class AdviceAdapter
extends GeneratorAdapter
implements Opcodes

A MethodAdapter to dispatch method body instruction

The behavior is like this:

as long as the INVOKESPECIAL for the object initialization has not been reached, every bytecode instruction is dispatched in the ctor code visitor
when this one is reached, it is only added in the ctor code visitor and a JP invoke is added
after that, only the other code visitor receives the instructions
