Chapter 12


This chapter describes how to create ToolTalk specs for objects your application creates and manages. Before you can identify the type of objects, you need to define otypes and store them in the ToolTalk Types Database. See for more information on otypes.

The ToolTalk service uses spec and otype information to determine object-oriented message recipients.

Note - Programs coded to the ToolTalk object-oriented messaging interface are not portable to CORBA-compliant systems without source changes.
