type Ref is limited new Ada.Finalization.Limited_Controlled and DDS.Condition.Ref with private;
Construct a new guard condition with trigger value DDS.BOOLEAN_FALSE.
Raises: DDS.RETCODE_OUT_OF_RESOURCES if a new DDS.GuardCondition could not be allocated.
Important: The DDS.GuardCondition allocates native resources. When DDS.GuardCondition is no longer being used, user should call DDSGuardCondition::~DDSGuardCondition explicitly to properly cleanup all native resources.

Releases the resources associated with this object.
Calling this method multiple times on the same object is safe; subsequent deletions will have no effect.

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