Connection Object

Class Code: 05hex

The Connection Class allocates and manages the internal

resources associated with both I/O and Explicit Messaging

Connections. The specific instance generated by the

Connection Class is referred to as a Connection Instance or

a Connection Object.

A Connection Object within a particular module actually

represents one of the end-points of a Connection. It is pos-

sible for one of the Connection end-points to be configured

and “active” (e.g., transmitting) without the other end-

point(s) being present. Connection Objects are used to

model the communication specific characteristics of a par-

ticular application-to-application relationship.

A specific Connection Object Instance manages the commu-

nication-specific aspects related to an end-point.
