java设计模式-中介者模式

//通用抽象中介者
public abstract class Mediator {
    //定义同事类 
    protected ConcreteColleague1 c1;
    protected ConcreteColleague2 c2;
    //getter/setter ... 
    //中介者模式的业务逻辑 
    public abstract void doSomething1();
    public abstract void doSomething2();
}

//通用中介者
public class ConcreteMediator extends Mediator {
    @Override
    public void doSomething1(){
        super.c1.selfMethod1();
        super.c2.selfMethod2();
    }
    public void doSomething2(){
        super.c1.selfMethod1();
        super.c2.selfMethod2();
    }
}

//抽象同事类
public abstract class Colleague {
    protected Mediator mediator;
    public Colleague(Mediator _mediator) {
        this.mediator = _mediator;
    }
}

//具体同事类
public class ConcreteColleague1 extends Colleague {
    //通过构造函数传递中介者  
    public ConcreteColleague1(Mediator _mediator){
        super(_mediator);
    }
    //自有方法 self-method  
    public void selfMethod1(){
        //处理自己的业务逻辑  
    }
    //依赖方法 dep-method  
    public void depMethod1(){
        //处理自己的业务逻辑
        //自己不能处理的业务逻辑，委托给中介者处理  
        super.mediator.doSomething1();
    }
}

public class ConcreteColleague2 extends Colleague {
    //通过构造函数传递中介者  
    public ConcreteColleague2(Mediator _mediator){
        super(_mediator);
    } //自有方法 self-method  public void selfMethod2(){ 
    //处理自己的业务逻辑  
}
    //依赖方法 dep-method  
    public void depMethod2(){
        //处理自己的业务逻辑  
        //自己不能处理的业务逻辑，委托给中介者处理  
        super.mediator.doSomething2();
    }
