        Overrides:
        visitMethod in class ClassVisitor
        Parameters:
        access - the method's access flags (see Opcodes). This parameter also indicates if the method is synthetic and/or deprecated.
        name - the method's name.
        descriptor - the method's descriptor (see Type).
        signature - the method's signature. May be null if the method parameters, return type and exceptions do not use generic types.

        Returns:
        an object to visit the byte code of the method, or null if this class visitor is not interested in visiting the code of this method.
