// Created by Macheng on 2019/05/18.
// Description:
// This is a struct of abstract device. Any device either real or virtual
// must inherit from this struct, so that they have uniform properties like
// AVs and DVs and general functions like AddAV and AddDV etc.
//   In order to this, when an occurrence of changing come we can only
// modify this struct to adjust new situation.
