+## 目的
+使用空接口作为标记来区分特殊处理的对象。
+
+## 类图
+![alt text](./etc/MarkerDiagram.png "Marker Interface")
+
+## 适用场景
+在以下场景使用Marker Interface pattern
+
+* 您希望将特殊对象与普通对象区分开来（以不同方式处理它们）
+* 您希望标记某些对象可用于某些类型的操作
+
+## 应用案例
+
+* [javase.8.docs.api.java.io.Serializable](https://docs.oracle.com/javase/8/docs/api/java/io/Serializable.html)
+* [javase.8.docs.api.java.lang.Cloneable](https://docs.oracle.com/javase/8/docs/api/java/lang/Cloneable.html)
