This document describes the usage of the Interface Definition Language (IDL) and compilers used in the NMM project.
Within the NMM environment, IDL files are used to describe two things: the interfaces an object supports and the events and object should be able to process instream. From such an IDL description a set of IDL compilers generates source code. Four files are generated. An hpp- and cpp-file for the client side, and an hpp- and cpp-file for the server side. The client side is also called interface class; the server side is also called implementation class. An interface object will be used in an application program to control the server side object. The server class will be used as superclass for a class that wants to implement the interface.
