## Intent
Using empy interfaces as markers to distinguish special treated objects.
Using empty interfaces as markers to distinguish special treated objects.
![alt text](./etc/MarkerDiagram.png "Marker Interface")
## Applicability
Use the Marker Interface pattern when
* you want to identify the special objects from normal objects
* define a type that is implemented by instances of the marked class, marker annotations can not do that
* you want to identify the special objects from normal objects (to treat them differently)
* you want to mark that some object is available for certain sort of operations
## Real world examples

* [javase.7.docs.api.java.lang.Cloneable](https://docs.oracle.com/javase/7/docs/api/java/lang/Cloneable.html)
