An object-oriented application framework for the development of real-time systems

The paper presents an object-oriented application framework that supports the development of real-time systems. The framework consists of a set of architectural abstractions that allow time-related aspects to be explicitly treated as first-class objects at the application level. Both the temporal behavior of an application and the way the application deals with information placed in a temporal context can be modeled by means of such abstractions, thus narrowing the semantic gap between specification and implementation. Moreover, the framework carefully separates behavioral policies from implementation details improving portability and simplifying the realization of adaptive systems.
