AE Enschede, The Netherlands. Real-time programs are, in general, difficult to design and verify. We refer to this as the real-time specification inheritance anomaly. As a solution to these anomalies, the concept of real-time composition filters is introduced.
Filters affect the real-time characteristics of messages that are received or sent by an object.
Through proper configuration of filters, one can specify real-time constraints, and reuse of these constraints without causing inheritance anomalies.
