js 桥接模式与适配器模式

// 实现部分接口
class Implementor {
    operationImpl() {}
}

class ConcreteImplementorA extends Implementor {
    operationImpl() {
        return "ConcreteImplementorA";
    }
}

class ConcreteImplementorB extends Implementor {
    operationImpl() {
        return "ConcreteImplementorB";
    }
}

// 抽象部分
class Abstraction {
    constructor(implementor) {
        this.implementor = implementor;
    }

    operation() {
        return this.implementor.operationImpl();
    }
}

// 客户端代码
const implementorA = new ConcreteImplementorA();
const abstraction = new Abstraction(implementorA);
console.log(abstraction.operation()); // 输出: ConcreteImplementorA

// 需要适配的类
class Adaptee {
    specificRequest() {
        return "Specific request.";
    }
}

// 目标接口
class Target {
    request() {}
}

// 适配器
class Adapter extends Target {
    constructor(adaptee) {
        super();
        this.adaptee = adaptee;
    }

    request() {
        return this.adaptee.specificRequest();
    }
}

// 客户端代码
const adaptee = new Adaptee();
const adapter = new Adapter(adaptee);
console.log(adapter.request()); // 输出: Specific request.
