Expressing real-time constraints in a reflective object model

Abstract This paper focuses on the temporal aspects of RTGOL, a Real-Time Graphical Object-Oriented Language. First, the underlying object-model is briefly described, in particular the reflective architecture of active objects. Then a description mode that avoids inheritance anomaly is chosen. Next, the expression of temporal constraints and their propagation modes is detailed. At last, some examples show how to express common situations.
