The above example demonstrates RMI in Java. MyRemoteInterface extends the Remote interface and defines a single method sayHello(). MyRemoteObject implements this interface and provides the implementation for the sayHello() method. To use the MyRemoteObject instance remotely, it must be registered wit...
在 Java 编程语言中,空接口(marker interface)是一种非常有趣的设计模式,虽然它们看起来什么都不做,但是实际上它们在设计模式和程序结构中扮演着重要的角色。空接口是指那些没有方法或字段的接口。它们存在的原因以及它们所能实现的功能,往往超出了它们表面上的简单性。通过探讨 Java 中空接口的使用,我们可以深入...
标记接口有时也叫标签接口(Tag interface),即接口不包含任何方法。在Java里很容易找到标记接口的例子,比如JDK里的Serializable接口就是一个标记接口。 首先明确一点,Marker Interface(标记接口)决不是Java这门编程语言特有的,而是计算机科学中一种通用的设计理念。 我们看Wikipedia里对标记接口的定义。 “The tag/ mark...

If so, you should use a marker interface in preference to an annotation. This will make it possible for you to use the interface as a parameter type for the methods in question, which will result in the very real benefit of compile-time type checking. ...

In you BAdI definition, it is impossible to use an interface without including this tag interface. Even if you bypass this check via tricks like debugging in ABAP layer, there is still kernel check in the runtime as last defense. Tag interface in Java As I mentioned the tag interface is ...
