Dimple is a simple interceptor framework that can be used to intercept, stub or decorate third party interfaces (such as Connection, java.util.Map).

Interceptors, stub and decorators created by dimple is free of versioning problem (where you implemented two methods declared by version 1 but later on version 2 declares 2 more methods).

The use of dimple is intuitive. It can be viewed as a duck typing solution in Java, where implements SomeInterface is not required for a class for it to be used as SomeInterface.
