摘要
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. Their 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. (C) 1998 Elsevier Science Ltd. All rights reserved.
