/**
 * A {@link MethodVisitor} to insert before, after and around advices in methods and constructors.
 *
 * 
The behavior for constructors is the following:
 *
 * 

 *   
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
