OSA reference

Object service agents (OSA) manage classes that manage objects in response to requests from SCOadmin managers. An OSA consists of classes with class definition tables and execution procedures.

To create an OSA you should:

understand how the Server API processes requests and handles errors - ``OSAs and the Server API''
define class attributes, identifiers, and valid operations in definition tables - ``Creating class definition tables''
write procedures that the OSA will perform on attributes or objects of a class - ``Defining execution procedures''

An OSA may be implemented either in Tcl or C/C++. Examples are provided for both in ``Example tables and procedures''.
