Parallel objects in distributed Ada95 compiler and running system -- PDEFA

摘要

Ada9S is an object-oriented concurrent programming language. PDEFA is a distributed Ada95 system. In PDEFA, task and protected objects in Ada95 are turned into independent and service objects respectively, and run under the control of a daemonprogram Independent and service objects in PDEFA are called parallel objects. An independent object performs operations of its own, while a service object provides service to other parallel objects. A daemon manages all parallel objects and regulatestheir creation and termination.
