适配器模式

• Adapter, 用来匹配接口
• 类

  • public class Source(){
        public void method1(){}
    }
    public interface Targetable {
        public void method1()
        public void method2()
    }
    public class Adapter extends Source implements Targetable {
        @Override
        public void method2(){}
    }

• 对象

  • public class Wrapper implements Targetable {
        private Source source;
        public Wrapper(Source source){
            super();
            this.source = source;
        }
        @Override
        public void method1(){
            source.method1()
        }
        @Override
        public void method2(){}
    }

• 接口

  • public abstract class AbstractTarget implements Targetable {
        @Override
        public void method1(){}
    }
    public class Adapter extends AbstractTarget {
        @Override
        public method2(){}
    }
