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.

Constructor & Destructor Documentation

DDSGuardCondition::DDSGuardCondition ( )

No argument constructor.

The default constructor initializes the guard condition with trigger value DDS_BOOLEAN_FALSE

virtual DDSGuardCondition::~DDSGuardCondition ( )

virtual

Destructor.

Releases the resources associated with this object.

MT Safety:: UNSAFE. In VxWorks, it is unsafe to call this method while another thread may be simultaneously calling DDSDomainParticipantFactory::get_instance, DDSDomainParticipantFactory::finalize_instance, DDS_TypeCodeFactory::get_instance, DDSGuardCondition::DDSGuardCondition, DDSWaitSet::DDSWaitSet(), DDSWaitSet::DDSWaitSet(const DDS_WaitSetProperty_t&), DDSGuardCondition::~DDSGuardCondition, DDSWaitSet::~DDSWaitSet(), NDDSUtilityNetworkCapture::enable, or NDDSUtilityNetworkCapture::disable.

Deleting a NULL condition is safe and has no effect.

virtual DDS_Boolean DDSGuardCondition::get_trigger_value ( )

virtual

Retrieve the trigger_value.

virtual DDS_ReturnCode_t DDSGuardCondition::set_trigger_value ( DDS_Boolean value )

virtual

Set the guard condition trigger value.

Parameters

value <<in>> the new trigger value.
