APPLICATIVE OBJECT INTERCONNECTION IN A GRAPHICAL DESIGN FOR REAL-TIME APPLICATIONS

The LACATRE environment is dedicated to multitasking real-time applica tion developments. At the lowest level, it handles basic objects close to those supported by realtime executives (tasks, messages, semaphore s...), and at the highest one, it manipulates applicative objects whic h are near to the application programmer's preoccupations. The aim of this paper is to show how it is possible to build re-usable graphical communication interfaces, easily and efficiently, for the interconnect ion of these high-level applicative objects when they are involved in a client-server relation.
