Posted by: Jove Posted on: 2004-05-14 17:54 Java中的"回调函数"一般是用接口来实现的,如 public class Test{ public static void main(String[] args){ FooBar foo=new FooBar(); foo.setCallBack(new ICallBack(){ public void postExec(){System.out.println("method executed.");} }); } } public interface ICallBack(){ void postExec(); } public class FooBar..{ private ICallBack callBack; public void setCallBack(ICallBack callBack){ this.callBack=callBack; } public void doSth(){ .... callBack.postExec(); } .. } 也可以使用Observer模式来实现类似的功能 |
