Java设计模式之桥接模式详解

// 实现部分接口
public interface Implementor {
    void operationImpl();
}
// 具体实现类A
public class ConcreteImplementorA implements Implementor {
    @Override
    public void operationImpl() {
        // 具体实现逻辑
    }
}
// 具体实现类B
public class ConcreteImplementorB implements Implementor {
    @Override
    public void operationImpl() {
        // 具体实现逻辑
    }
}
// 抽象部分
public abstract class Abstraction {
    protected Implementor implementor;
    public Abstraction(Implementor implementor) {
        this.implementor = implementor;
    }
    public abstract void operation();
}
// 具体抽象类
public class RefinedAbstraction extends Abstraction {
    public RefinedAbstraction(Implementor implementor) {
        super(implementor);
    }
    @Override
    public void operation() {
        // 具体操作逻辑
        implementor.operationImpl();
    }
}

// 抽象图形类
public abstract class Shape {
    protected DrawingAPI drawingAPI;
    public Shape(DrawingAPI drawingAPI) {
        this.drawingAPI = drawingAPI;
    }
    public abstract void draw();
}
// 具体图形类
public class Circle extends Shape {
    private int x, y, radius;
    public Circle(int x, int y, int radius, DrawingAPI drawingAPI) {
        super(drawingAPI);
        this.x = x;
        this.y = y;
        this.radius = radius;
    }
    @Override
    public void draw() {
        drawingAPI.drawCircle(x, y, radius);
    }
}
