Detailed Description

The RtecEventChannelAdmin::EventChannel implementation.

This class is the Mediator between all the classes in the EC implementation, its main task is to redirect the messages to the right components, to hold and manage the lifetime of the long lived objects (Timer_Module, SupplierAdmin, ConsumerAdmin and Dispatching) and to provide a simpler interface to the EC_Factory.

Member Enumeration Documentation

anonymous enum [protected]

Flag to track the status of the event channel.

Enumerator:
