GuardConditions are created by your application. GuardConditions provide a way for your application to manually awaken a WaitSet. Like all Conditions, it has a single boolean trigger_value. Your application can manually trigger the GuardCondition by calling set_trigger_value().
Connext DDS does not trigger or clear this type of condition—it is completely controlled by your application.
A GuardCondition has no factory. It is created as an object directly by the natural means in each language binding (e.g., using “new” in C++ or Java). For example:
// Create a Guard Condition Condition* my_guard_condition = new GuardCondition(); // Delete a Guard Condition delete my_guard_condition;
When first created, the trigger_value is FALSE.
A GuardCondition has only two operations, get_trigger_value() and set_trigger_value().
When your application calls set_trigger_value(DDS_BOOLEAN_TRUE), Connext DDS will awaken any WaitSet to which the GuardCondition is attached.
