CIAO::DDS4CCM::DomainParticipantManager Class Reference

Stores a DDSParticipantTopic per domain ID and QOS profile string. When several connectors are joining the same domain ID, using the same QOS settings (ie have the same QOS profile string), the DomainParticipant for that combination is shared. This is done to save resources (running threads/memory usage). More...

Detailed Description

Stores a DDSParticipantTopic per domain ID and QOS profile string. When several connectors are joining the same domain ID, using the same QOS settings (ie have the same QOS profile string), the DomainParticipant for that combination is shared. This is done to save resources (running threads/memory usage).

The DomainParticipantManager is a singleton.

Member Function Documentation

bool CIAO::DDS4CCM::DomainParticipantManager::close

(

)

Try to close the DPM, at the moment no domain participants are registered anymore we are going to shutdown DDS interaction

DDS::DomainParticipant_ptr CIAO::DDS4CCM::DomainParticipantManager::get_participant	(	const DDS::DomainId_t	domain_id,
		const char *	qos_profile
	)

Searches for the DomainParticipant_ptr in the internal map. Search is based on the given domain ID and the given QOS (QOS profile string). If found, it'll increment the reference count of the DDSParticipantTopic instance.

bool CIAO::DDS4CCM::DomainParticipantManager::register_participant	(	DDS::DomainId_t	domain_id,
		const char *	qos_profile,
		DDS::DomainParticipant_ptr	dp
	)

Adding a DDSParticipantTopic instance when the internal maps doesn't contain a reference. Returns false if there's already an DDSParticipantTopic available (base on domain ID and QOS)

bool CIAO::DDS4CCM::DomainParticipantManager::unregister_participant	(	DDS::DomainId_t	domain_id,
		const char *	qos_profile,
		DDS::DomainParticipant_ptr	dp
	)

Removes the DDSParticipantTopic instance when the reference count is one. Returns false if the reference count of the corresponding DDSParticipantTopic was not nil
