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/ marker interface pattern is a design pattern in computer science, u...

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. ...

java marker interface marker interface是一种特殊的接口,这种接口没有任何属性或者方法,java开发者最常用的marker interface应该当属Serializable了,当一个实体类需要通过网络传输时需要确保该类可以被序列化...这种接口存在的意义在于其对java编译器的作用,marker interface告知java编译器实现marker interface的类不是一般...
