Detailed Description

<<interface>> A specific DDSCondition whose trigger_value is completely under the control of the application.

The DDSGuardCondition provides a way for an application to manually wake up a DDSWaitSet. This is accomplished by attaching the DDSGuardCondition to the DDSWaitSet and then setting the trigger_value by means of the DDSGuardCondition::set_trigger_value operation.
