This article mainly introduces the relevant knowledge of "how to apply Memento mode in C++". The editor shows you the operation process through an actual case. The method of operation is simple, fast and practical. I hope this article "how to apply Memento mode in C++" can help you solve the problem.

Example of C++ Memento mode code:

# include

< iostream>

# include

< string>

Using namespace std; typedef string states; class Memento; class Orininator {public: Orininator () {mantist = ""; mechestrist0;}; Orininator (const states& st) {mpracticstat;}; ~ Orininator () {}; Memento* CreateMemento (); void SetMemento (Memento* men) {}; void RestoretoMen (Memento* mt); states GetState () {return massistsdt;}; void SetState (const states& sdt) {mantistat;} void PrintState () {cout

< this->

M_st

< < ".."< < endl;} private: states m_st; Memento* m_mt; };class Memento { private: friend class Orininator;//友元 Memento(){}; Memento(const states& st){m_st=st;}; ~Memento(){}; void SetState(const states& std){m_st=std;}; states GetState(){return m_st;}; private: states m_st; };Memento* Orininator::CreateMemento() { return new Memento(m_st);//合理的应用构造函数； } void Orininator::RestoretoMen(Memento* mt) { this->

Void main () {Orininator* Ori=new Orininator (); Ori- > SetState ("old"); Ori- > PrintState (); Memento* masked Origin-> CreateMemento (); Ori- > SetState ("new"); Ori- > PrintState (); Ori- > RestoretoMen (m); Ori- > PrintState ();} that's all for "how to apply Memento pattern in C++".
