桥接模式

桥接模式

• 把事物与具体的实现分开，就是进行解耦

定义一个接口

public interface Sourceable {
    public void method();
}

实现类1

public class SourceSub1 implements Sourceable {

    @Override
    public void method() {
        System.out.println("this is the first sub!");
    }
}

实现类2

public class SourceSub2 implements Sourceable {

    @Override
    public void method() {
        System.out.println("this is the second sub!");
    }
}

桥接类

在这个桥接类里面进行，其他两个对象封装，实现调用
public abstract class Bridge {
    private Sourceable source;

    public void method(){
        source.method();
    }

    public Sourceable getSource() {
        return source;
    }

    public void setSource(Sourceable source) {
        this.source = source;
    }
}

调用类

public class MyBridge extends Bridge {
    public void method(){
        getSource().method();
    }
}

测试类

public class BridgeTest {

    public static void main(String[] args) {

        Bridge bridge = new MyBridge();

        /*调用第一个对象*/
        Sourceable source1 = new SourceSub1();
        bridge.setSource(source1);
        bridge.method();

        /*调用第二个对象*/
        Sourceable source2 = new SourceSub2();
        bridge.setSource(source2);
        bridge.method();
    }
}
