package com.xfcz.behaviour.memento.blankbox;


public class Originator {
    private String state;

    public IMemento createMemento(){
        return new Memento(state);
    }

    public void restoreMemento(IMemento menmento){
        this.setState(((Memento)menmento).getState());
    }

    public String getState() {

        return state;
    }

    public void setState(String state) {
        System.out.println("當前狀態："+state);
        this.state = state;
    }

    private class Memento implements IMemento{
        private String state;

        public Memento(String state){
            setState(state);
        }

        public String getState() {
            return state;
        }

        public void setState(String state) {
            this.state = state;
        }
    }
}

我就是測試一下
