It might be helpful to rewrite it: an interface based framework is a framework that only allows users / clients lib to access interfaces and actually provides classes that implement these interfaces The advantage of this method is to give the implementer complete control of the implementation and provide a stable API for the client I recently encountered an example in which a client obtains xmlprocessor. XML from an API method Within the framework, the processor has three completely different implementations: domxmlprocessor, saxxmlprocessor and vtdxmlprocessor The details of each implementation have nothing to do with the customer and can be switched at any time
