Framework, design patterns and pattern language for object concurrency

The development of concurrent applications is hard due to the diverse concerns involved and the non-determinism inherent to the implementation environment. In order to control such complexity, developers can benefit from object-oriented frameworks providing application-independent solutions which can be specialized for the application-specific needs. A primary contribution of this paper is to describe a family of design patterns for object concurrency which are composed in a three-layered framework. In addition, a pattern language describing an incremental development process which is based on the framework and design patterns is also presented.
