Function Documentation

DDS_ReturnCode_t DPSE_DiscoveryPluginProperty_initialize

(

struct DPSE_DiscoveryPluginProperty *

dst

)

Initialize a DiscoveryPluginProperty structure.

DDS_ReturnCode_t DPSE_RemoteParticipant_assert	(	DDS_DomainParticipant *const	participant,
		const char *	rem_participant_name
	)

<<cert>> Assert remote participant by passing in the name of that participant.

DPSE discovery requires that you pre-configure your application with information about any remote participants that you intend to discover. The only information that needs to be pre-configured is the name of the remote DDS_DomainParticipant that your application intends to discover.

DDS_ReturnCode_t DPSE_RemotePublication_assert	(	DDS_DomainParticipant *const	participant,
		const char *const	rem_participant_name,
		const struct DDS_PublicationBuiltinTopicData *const	data,
		NDDS_TypePluginKeyKind	key_kind
	)

<<cert>> Assert remote publication by passing in the builtin data that describes the type, topic, and QoS of that remote publication.

DPSE discovery requires that you pre-configure your application with information about any remote publications that you intend to discover and receive data from. The DDS_PublicationBuiltinTopicData field must include the topic name, type name, and QoS of the remote DDS_DataWriter that you intend to receive communications from.

Additionally, this method takes a key_kind argument that must match the key kind returned by the type plugin.

DDS_ReturnCode_t DPSE_RemoteSubscription_assert	(	DDS_DomainParticipant *const	participant,
		const char *const	rem_participant_name,
		const struct DDS_SubscriptionBuiltinTopicData *const	data,
		NDDS_TypePluginKeyKind	key_kind
	)

<<cert>> Assert remote subscription by passing in the builtin data that describes the type, topic, and QoS of that remote subscription.

DPSE discovery requires that you pre-configure your application with information about any remote subscriptions that you intend to discover and send data to. The DDS_SubscriptionBuiltinTopicData parameter must include the topic name, type name, and QoS of the remote DDS_DataReader that your application intends to send data to. Additionally, if the remote DDS_DataReader is listening on a non-default port, you must set the remote locator (including the non-default port) in the DDS_SubscriptionBuiltinTopicData that you intend to use to contact the remote DDS_DataReader.

Additionally, this method takes a key_kind argument that must match the key kind returned by the type plugin.

struct RT_ComponentFactoryI* DPSE_DiscoveryFactory_get_interface ( void  )

read

Gets the singleton instance of the DPSE discovery plugin factory. The singleton instance of the factory is used when creating a domain participant.

This function gets the single singleton instance of the DPSE discovery plugin factory that is used by the middleware to create a DPSE plugin. In the future, as more discovery plug-ins are supported, they will be registered with the middleware by installing different discovery factory instances with the DDS_DomainParticipantFactory. The singleton instance of the factory is registered with a name, and that name is specified in the DDS_DomainParticipant DDS_DiscoveryQosPolicy. This is used to create a discovery plug-in instance when creating a domain participant.

Returns:

Pointer to DPSE discovery plugin factory

DDS_DiscoveryQosPolicy

const char* DPSE_DiscoveryFactory_get_version

(

void

)

Returns the version string for the DPSE library.
