Function Documentation

◆ matched_subscription_participant_data()

template<typename T >

dds::topic::ParticipantBuiltinTopicData rti::pub::matched_subscription_participant_data	(	const dds::pub::DataWriter< T > &	writer,
		const dds::core::InstanceHandle &	handle
	)

<<extension>> This operation retrieves the information on the discovered dds::domain::DomainParticipant associated with the subscription that is currently matching with the dds::pub::DataWriter.

Note: This is a standalone function in the namespace rti::pub

The subscription_handle must correspond to a subscription currently associated with the dds::pub::DataWriter. Otherwise, the operation will fail with dds::core::InvalidArgumentError. The operation may also fail with dds::core::PreconditionNotMetError if the subscription corresponds to the same dds::domain::DomainParticipant that the DataWriter belongs to. Use dds::pub::matched_subscriptions() to find the subscriptions that are currently matched with the dds::pub::DataWriter.

Exceptions

One	of the Standard Exceptions, or dds::core::NotEnabledError

Template Parameters

T	The topic-type that the DataWriter subscribes to

Parameters

writer	The writer to lookup the matched participant data of
handle	The InstanceHandle to a specific subscription. Must correspond to a subscription currently associated with the DataWriter.

Returns: The dds::topic::ParticipantBuiltinTopicData of the DomainParticipant of a matched subscription of a dds::pub::DataWriter

◆ matched_subscriptions_locators()

template<typename T >

rti::core::LocatorSeq rti::pub::matched_subscriptions_locators ( const dds::pub::DataWriter< T > & writer )

<<extension>> Retrieve the list of locators for subscriptions currently associated with this DataWriter.

The locators returned are the ones that are used by the DDS implementation to communicate with the corresponding matched DataReaders.

Template Parameters

T	The topic-type that the DataWriter publishes.

Parameters

writer The DataWriter.

Returns: The list of locators

◆ is_matched_subscription_active()

template<typename T >

bool rti::pub::is_matched_subscription_active	(	const dds::pub::DataWriter< T > &	writer,
		const dds::core::InstanceHandle &	handle
	)

<<extension>> Check if a matched subscription is active.

Note: This is a standalone function in the namespace rti::pub

Template Parameters

T	The topic-type that the DataWriter publishes.

Parameters

writer	The DataWriter.
handle	The dds::core::InstanceHandle of the matched subscription.

This API is used for querying the endpoint liveliness of a matched subscription. A matched subscription will be marked as inactive when it becomes nonprogessing (e.g., not responding to a DataWriter's heartbeats, or letting its internal queue fill up without taking the available data). Note that if the participant associated with the matched subscription loses liveliness, the dds::core::InstanceHandle will become invalid and this function will fail with dds::core::InvalidArgumentError.

Returns: A boolean indicating whether or not the matched subscription is active.

◆ matched_subscription_data()

template<typename T >

std::vector< dds::topic::SubscriptionBuiltinTopicData > rti::pub::matched_subscription_data ( const dds::pub::DataWriter< T > & writer )

<<extension>> Obtain the SubscriptionBuiltinTopicData for all of the subscriptions matched with a DataWriter.

Note: This is a standalone function in the namespace rti::pub

This API retrieves the matched publication data from all of the subscriptions currently matched a DataWriter.

Template Parameters

T	The topic-type that the DataWriter publishes.

Parameters

writer The DataWriter.

Returns: A std::vector containing all of the matched subscription data.

		const std::string &	topic_name
	)

<<extension>> Retrieves a dds::pub::DataWriter with the given name within the dds::pub::Publisher

Note: This is a standalone function in the namespace rti::pub

Every dds::pub::DataWriter in the system has an entity name which is configured and stored in the <<extension>> EntityName policy, ENTITY_NAME.

This operation retrieves the dds::pub::DataWriter within the dds::pub::Publisher whose name matches the one specified. If there are several dds::pub::DataWriter with the same name within the dds::pub::Publisher, the operation returns the first matching occurrence.

		const std::string &	datawriter_name
	)

<<extension>> Retrieves a dds::pub::DataWriter with the given name within the dds::pub::Publisher

Note: This is a standalone function in the namespace rti::pub

Every dds::pub::DataWriter in the system has an entity name which is configured and stored in the <<extension>> EntityName policy, ENTITY_NAME.

This operation retrieves the dds::pub::DataWriter within the dds::pub::Publisher whose name matches the one specified. If there are several dds::pub::DataWriter with the same name within the dds::pub::Publisher, the operation returns the first matching occurrence.

Template Parameters

Writer The type of the writer. It can be dds::pub::AnyDataWriter, or an instantiation of dds::pub::DataWriter<T> (if T is not the correct type, this function throws dds::core::InvalidDowncastError)

Parameters

publisher	The dds::pub::Publisher that created the DataWriter to find
datawriter_name	Entity name of the DataWriter to find

Returns: The WRITER with the given name

See also: Looking up DataWriters

◆ find_datawriter_by_name() [2/2]

template<typename Writer >

Writer rti::pub::find_datawriter_by_name	(	dds::domain::DomainParticipant	participant,
		const std::string &	datawriter_name
	)

<<extension>> Retrieves a dds::pub::DataWriter within the dds::domain::DomainParticipant with the given name

Note: This is a standalone function in the namespace rti::pub

Every dds::pub::DataWriter in the system has an entity name which is configured and stored in the EntityName policy, ENTITY_NAME.

Every dds::pub::Publisher in the system has an entity name which is also configured and stored in the EntityName policy.

This operation retrieves a dds::pub::DataWriter within a dds::pub::Publisher given the specified name which encodes both to the dds::pub::DataWriter and the dds::pub::Publisher name.

If there are several dds::pub::DataWriter with the same name within the corresponding dds::pub::Publisher this function returns the first matching occurrence.

The specified name might be given as a fully-qualified entity name or as a plain name.

The fully qualified entity name is a concatenation of the dds::pub::Publisher to which the dds::pub::DataWriter belongs and the entity name of of the dds::pub::DataWriter itself, separated by a double colon "::". For example: MyPublisherName::MyDataWriterName

The plain name contains the dds::pub::DataWriter name only. In this situation it is implied that the dds::pub::DataWriter belongs to the implicit dds::pub::Publisher so the use of a plain name is equivalent to specifying a fully qualified name with the dds::pub::Publisher name part being "implicit". For example: the plain name "MyDataWriterName" is equivalent to specifiying the fully qualified name "implicit::MyDataWriterName"

The dds::pub::DataWriter is only looked up within the dds::pub::Publisher specified in the fully qualified name, or within the implicit dds::pub::Publisher if the name was not fully qualified.

Template Parameters

Writer The type of the writer. It can be dds::pub::AnyDataWriter, or an instantiation of dds::pub::DataWriter<T> (if T is not the correct type, this function throws dds::core::InvalidDowncastError)

Parameters

participant	The dds::domain::DomainParticipant within which the dds::pub::DataWriter exists
datawriter_name	EntityName of the DataWriter to find

Returns: The WRITER with the given name

See also: implicit_publisher(const dds::domain::DomainParticipant& dp);; Looking up DataWriters

◆ implicit_publisher()

dds::pub::Publisher rti::pub::implicit_publisher ( const dds::domain::DomainParticipant & dp )

<<extension>> Get the implicit dds::pub::Publisher for a given dds::domain::DomainParticipant.

Note: This is a standalone function in the namespace rti::pub

If an implicit Publisher does not already exist, this creates one.

The implicit Publisher is created with default dds::pub::qos::PublisherQos and no listener. When a DomainParticipant is deleted, if there are no attached dds::pub::DataWriter that belong to the implicit Publisher, the implicit Publisher will be implicitly deleted.

MT Safety:: UNSAFE. It is not safe to create an implicit Publisher while another thread may be simultaneously calling dds::domain::DomainParticipant::default_publisher_qos.

Parameters

dp	The DomainParticipant that the implicit publisher belongs to

Returns: The implicit publisher

◆ find_flow_controller()

FlowController find_flow_controller	(	dds::domain::DomainParticipant	participant,
		const std::string &	name
	)

Retrieves an existing FlowController.

Note: This is a standalone function in the namespace rti::pub

Parameters

participant	The DomainParticipant associated to the FlowController
name	The name used to create the FlowController or the name of one of the built-in FlowControllers (FlowController::DEFAULT_NAME, FlowController::FIXED_RATE_NAME, FlowController::ON_DEMAND_NAME)

Returns: The flow controller with that name in that participant or an empty reference (equals to dds::core::null) if it doesn't exist
