DDS_DomainParticipant entity and associated elements
| #define DDS_DomainParticipantListener_INITIALIZER |
Initializer for new DDS_DomainParticipantListener.
No memory is allocated. New DDS_DomainParticipantListener instances stored in the stack should be initialized with this value before they are passed to any functions.
| #define DDS_DomainParticipantQos_INITIALIZER |
Initializer for new QoS instances.
New DDS_DomainParticipantQos instances stored on the stack should be initialized with this value before they are passed to any functions. This step ensures that those contained QoS policies that use dynamic memory are properly initialized. This does not allocate memory.
The simplest way to create a new QoS structure is to initialize it on the stack at the time of its creation:
Note that the above assignment is not a substitute for calling DDS_DomainParticipant_get_qos or DDS_DomainParticipantFactory_get_default_participant_qos; one of those functions should be called subsequently to setting the QoS of any new or existing entity. DDS_DomainParticipantQos_finalize should be called to free the contained QoS policies that use dynamic memory:
| typedef struct DDS_DomainParticipantImpl DDS_DomainParticipant |
<<interface>> Container for all DDS_DomainEntity objects.
The DomainParticipant object plays several roles:
- It acts as a container for all other DDS_Entity objects.
- It acts as factory for the DDS_Publisher, DDS_Subscriber, DDS_Topic and DDS_MultiTopic DDS_Entity objects.
- It represents the participation of the application on a communication plane that isolates applications running on the same set of physical computers from each other. A domain establishes a virtual network linking all applications that share the same domainId and isolating them from applications running on different domains. In this way, several independent distributed applications can coexist in the same physical network without interfering, or even being aware of each other.
- It provides administration services in the domain, offering operations that allow the application to ignore locally any information about a given participant (ignore_participant()), publication (ignore_publication()), subscription (ignore_subscription()) or topic (ignore_topic()).
The following operations may be called even if the DDS_DomainParticipant is not enabled. (Operations NOT in this list will fail with the value DDS_RETCODE_NOT_ENABLED if called on a disabled DomainParticipant).
| DDS_ReturnCode_t DDS_DomainParticipantQos_initialize | ( | struct DDS_DomainParticipantQos * | self | ) |
Initializer for new QoS instances.
New DDS_DomainParticipantQos instances on heap should be initialized with this function before they are passed to any functions. This step ensures that those contained QoS policies that use dynamic memory are properly initialized. This function does not allocate memory.
Calling this function is not a substitute for calling DDS_DomainParticipant_get_qos or DDS_DomainParticipantFactory_get_default_participant_qos; one of those functions should be called subsequently to setting the QoS of any new or existing entity. DDS_DomainParticipantQos_finalize should be called to free the contained QoS policies that use dynamic memory:
| self | <<in>> Cannot be NULL. |
| DDS_ReturnCode_t DDS_DomainParticipantQos_copy | ( | struct DDS_DomainParticipantQos * | self, |
| const struct DDS_DomainParticipantQos * | source | ||
| ) |
Copy the contents of the given QoS into this QoS.
DDS_DomainParticipantQos instances can use dynamic memory because of the sequences contained in some QoS policies. A shallow copy by assignment is therefore unsafe. This function performs a deep-copy, allocating memory if necessary.
| DDS_ReturnCode_t DDS_DomainParticipantQos_finalize | ( | struct DDS_DomainParticipantQos * | self | ) |
Free any dynamic memory allocated by the policies in this DDS_DomainParticipantQos.
Some QoS policies may use dynamic memory (regardless of whether the QoS itself is in dynamic memory). This function frees that memory but otherwise leaves this QoS unchanged. It should be called on all instances before they are freed (or, in the case of stack-based instances, before they go out of scope).
This function does not leave this object in an invalid state. It is permissable to finalize a QoS and then subsequently allocate new dynamic memory in one or more of its QoS policies.
Note that if this QoS instance is stored in heap memory, calling this function will not call free() on it; the user is responsible for explicitly freeing any heap-based QoS instance after calling this function.
| self | <<in>> Cannot be NULL. |
| DDS_Entity* DDS_DomainParticipant_as_entity | ( | DDS_DomainParticipant * | domain | ) |
Access a DDS_DomainParticipant's supertype instance.
| domain | <<in>> Cannot be NULL. |
| DDS_ReturnCode_t DDS_DomainParticipant_get_default_topic_qos | ( | DDS_DomainParticipant * | self, |
| struct DDS_TopicQos * | qos | ||
| ) |
Copies the default DDS_TopicQos values for this domain participant into the given DDS_TopicQos instance.
The retrieved qos will match the set of values specified on the last successful call to DDS_DomainParticipant_set_default_topic_qos, or else, if the call was never made, the default values listed in DDS_TopicQos.
This function may potentially allocate memory depending on the sequences contained in some QoS policies.
| DDS_ReturnCode_t DDS_DomainParticipant_set_default_topic_qos | ( | DDS_DomainParticipant * | self, |
| const struct DDS_TopicQos * | qos | ||
| ) |
Set the default DDS_TopicQos values for this domain participant.
This default value will be used for newly created DDS_Topic if DDS_TOPIC_QOS_DEFAULT is specified as the qos parameter when DDS_DomainParticipant_create_topic is called.
qos parameter. | self | <<in>> Cannot be NULL. |
| qos | <<in>> Default qos to be set. The special value DDS_TOPIC_QOS_DEFAULT may be passed as qos to indicate that the default QoS should be reset back to the initial values the factory would used if DDS_DomainParticipant_set_default_topic_qos had never been called. Cannot be NULL. |

<<eXtension>> Set the default DDS_TopicQos values for this domain participant based on the input XML QoS profile.
This default value will be used for newly created DDS_Topic if DDS_TOPIC_QOS_DEFAULT is specified as the qos parameter when DDS_DomainParticipant_create_topic is called.
qos parameter. | self | <<in>> Cannot be NULL. |

If the input profile cannot be found the function fails with DDS_RETCODE_ERROR.
| DDS_ReturnCode_t DDS_DomainParticipant_get_default_publisher_qos | ( | DDS_DomainParticipant * | self, |
| struct DDS_PublisherQos * | qos | ||
| ) |
Copy the default DDS_PublisherQos values into the provided DDS_PublisherQos instance.
The retrieved qos will match the set of values specified on the last successful call to DDS_DomainParticipant_set_default_publisher_qos, or DDS_DomainParticipant_set_default_publisher_qos_with_profile, or else, if the call was never made, the default values listed in DDS_PublisherQos.
This function may potentially allocate memory depending on the sequences contained in some QoS policies.
If DDS_PUBLISHER_QOS_DEFAULT is specified as the qos parameter when DDS_DomainParticipant_create_topic is called, the default value of the QoS set in the factory, equivalent to the value obtained by calling DDS_DomainParticipant_get_default_publisher_qos, will be used to create the DDS_Publisher.

| const struct DDS_PublisherQos * | qos | ||
| ) |

<<eXtension>> Sets the default XML profile for a DDS_DomainParticipant.
This function specifies the profile that will be used as the default the next time a default DomainParticipant profile is needed during a call to one of this DomainParticipant's operations. When calling a DDS_DomainParticipant function that requires a profile_name parameter, you can use NULL to refer to the default profile. (This same information applies to setting a default library.)
If the default profile is not set, the DDS_DomainParticipant inherits the default from the DDS_DomainParticipantFactory (see DDS_DomainParticipantFactory_set_default_profile).
This function does not set the default QoS for entities created by the DDS_DomainParticipant; for this functionality, use the functions set_default_<entity>_qos_with_profile (you may pass in NULL after having called set_default_profile()).

If the DataWriter's DDS_DestinationOrderQosPolicy::kind is DDS_BY_SOURCE_TIMESTAMP_DESTINATIONORDER_QOS, calls to delete_datawriter() may fail if your application has previously used the 'with timestamp' APIs (write_w_timestamp(), register_instance_w_timestamp(), unregister_instance_w_timestamp(), or dispose_w_timestamp()) with a timestamp larger (later) than the time at which delete_datawriter() is called.

<<eXtension>> Register a content filter which can be used to create a DDS_ContentFilteredTopic.
DDS specifies a SQL-like content filter for use by content filtered topics. If this filter does not meet your filtering requirements, you can register a custom filter.
To use a custom filter, it must be registered in the following places:
For example, suppose Application A on the subscription side creates a Topic named X and a ContentFilteredTopic named filteredX (and a corresponding DataReader), using a previously registered content filter, myFilter. With only that, you will have filtering at the subscription side. If you also want to perform filtering in any application that publishes Topic X, then you also need to register the same definition of the ContentFilter myFilter in that application.
Each filter_name can only be used to registered a content filter once with a DDS_DomainParticipant.

<<eXtension>> Unregister a content filter previously registered with DDS_DomainParticipant_register_contentfilter.
A filter_name can be unregistered only if it has been previously registered to the DDS_DomainParticipant with DDS_DomainParticipant_register_contentfilter.
The unregistration of filter is not allowed if there are any existing DDS_ContentFilteredTopic objects that are using the filter. If the operation is called on a filter with existing DDS_ContentFilteredTopic objects attached to it, this operation will fail with DDS_RETCODE_PRECONDITION_NOT_MET.
If there are still existing discovered DDS_DataReader s with the same filter_name and the filter's compile method of the filter have previously been called on the discovered DDS_DataReader s, finalize method of the filter will be called on those discovered DDS_DataReader s before the content filter is unregistered. This means filtering will now be performed on the application that is creating the DDS_DataReader.

<<eXtension>> Creates a DDS_FlowController with the desired property.
The created DDS_FlowController is associated with a DDS_DataWriter via DDS_PublishModeQosPolicy::flow_controller_name. A single DDS_FlowController may service multiple DDS_DataWriter instances, even if they belong to a different DDS_Publisher. The property determines how the DDS_FlowController shapes the network traffic.

| fc | <<in>> The DDS_FlowController to be deleted. |
| const DDS_TypeCode* DDS_DomainParticipant_get_typecode_exp | ( | DDS_DomainParticipant * | self, |
| const char * | type_name | ||
| ) |
<<experimental>> <<eXtension>> Retrieves the DDS_TypeCode of a type registered with the DDS_DomainParticipant based on the registration name.
Every data type used in a DDS_DomainParticipant has a registered type name which is the name specified at the time the type is registered with the DDS_DomainParticipant.
This operation retrieves the DDS_TypeCode for the type given the registared type name. The type_name argument must correspond to a name used to register a type with the DDS_DomainParticipant. Otherwise, this method will return NULL.
Type registration in a DDS_DomainParticipant is performed by a call to the FooTypeSupport_register_type operation on a derived class of the DDS_TypeSupport interface.
Type registration might occur directly via an application call to the FooTypeSupport_register_type operation, or indirectly by the RTI Connext infrastructure as a result of parsing an XML configuration file that refers to that type.
If a type is registered by the RTI Connext infrastructure as a result of parsing an XML configuration file, the DDS_TypeSupport can be created either from a type description found in the XML files, or else by calling the FooTypeSupport_register_type operation on a DDS_TypeSupport that has been registered with DDS_DomainParticipantFactory. If a DDS_TypeSupport is registered with the DDS_DomainParticipantFactory this mechanism takes precedence over the creation of a DDS_TypeSupport from a type decription in the XML file.
To register a DDS_TypeSupport with the DDS_DomainParticipantFactory use the operation DDS_DomainParticipantFactory_register_type_support_exp.
If the DDS_TypeSupport is created from a type description found in the XML files, the resulting type support will be a DDS_DynamicDataTypeSupport. In this case the DDS_DataWriter and DDS_DataReader uses to write and read data of that type will be the DDS_DynamicDataWriter and DDS_DynamicDataReader, respectively.
| DDS_Topic* DDS_DomainParticipant_find_topic | ( | DDS_DomainParticipant * | self, |
| const char * | topic_name, | ||
| const struct DDS_Duration_t * | timeout | ||
| ) |
Finds an existing (or ready to exist) DDS_Topic, based on its name.
This call can be used to block for a specified duration to wait for the DDS_Topic to be created.
If the requested DDS_Topic already exists, it is returned. Otherwise, find_topic() waits until another thread creates it or else returns when the specified timeout occurs.
find_topic() is useful when multiple threads are concurrently creating and looking up topics. In that case, one thread can call find_topic() and, if another thread has not yet created the topic being looked up, it can wait for some period of time for it to do so. In almost all other cases, it is more straightforward to call DDS_DomainParticipant_lookup_topicdescription.
The DDS_DomainParticipant must already be enabled.
Note: Each DDS_Topic obtained by DDS_DomainParticipant_find_topic must also be deleted by means of DDS_DomainParticipant_delete_topic. If DDS_Topic is obtained multiple times by means of DDS_DomainParticipant_find_topic or DDS_DomainParticipant_create_topic, it must also be deleted that same number of times using DDS_DomainParticipant_delete_topic.
| self | <<in>> Cannot be NULL. |
| topic_name | <<in>> Name of the DDS_Topic to search for. Cannot be NULL. |
| timeout | <<in>> The time to wait if the DDS_Topic does not exist already. Cannot be NULL. |
| DDS_TopicDescription* DDS_DomainParticipant_lookup_topicdescription | ( | DDS_DomainParticipant * | self, |
| const char * | topic_name | ||
| ) |
Looks up an existing, locally created DDS_TopicDescription, based on its name.
DDS_TopicDescription is the base class for DDS_Topic, DDS_MultiTopic and DDS_ContentFilteredTopic. So you can narrow the DDS_TopicDescription returned from this operation to a DDS_Topic or DDS_ContentFilteredTopic as appropriate.
Unlike DDS_DomainParticipant_find_topic, which logically returns a new DDS_Topic object that must be independently deleted, this operation returns a reference to the original local object.
The DDS_DomainParticipant does not have to be enabled when you call lookup_topicdescription().
The returned topic may be either enabled or disabled.
| self | <<in>> Cannot be NULL. |
| topic_name | <<in>> Name of DDS_TopicDescription to search for. This string must be no more than 255 characters; it cannot be NULL. |
| DDS_FlowController* DDS_DomainParticipant_lookup_flowcontroller | ( | DDS_DomainParticipant * | self, |
| const char * | name | ||
| ) |
<<eXtension>> Looks up an existing locally-created DDS_FlowController, based on its name.
Looks up a previously created DDS_FlowController, including the built-in ones. Once a DDS_FlowController has been deleted, subsequent lookups will fail.
| self | <<in>> Cannot be NULL. |
| name | <<in>> Name of DDS_FlowController to search for. Limited to 255 characters. Cannot be NULL. |
| DDS_Subscriber* DDS_DomainParticipant_get_builtin_subscriber | ( | DDS_DomainParticipant * | self | ) |
Accesses the built-in DDS_Subscriber.
Each DDS_DomainParticipant contains several built-in DDS_Topic objects as well as corresponding DDS_DataReader objects to access them. All of these DDS_DataReader objects belong to a single built-in DDS_Subscriber.
The built-in Topics are used to communicate information about other DDS_DomainParticipant, DDS_Topic, DDS_DataReader, and DDS_DataWriter objects.
The built-in subscriber is created when this operation is called for the first time. The built-in subscriber is deleted automatically when the DDS_DomainParticipant is deleted.
| self | <<in>> Cannot be NULL. |
| DDS_Publisher* DDS_DomainParticipant_get_implicit_publisher | ( | DDS_DomainParticipant * | self | ) |
<<eXtension>> Returns the implicit DDS_Publisher. If an implicit Publisher does not already exist, this creates one.
There can only be one implicit Publisher per DomainParticipant.
The implicit Publisher is created with DDS_PUBLISHER_QOS_DEFAULT and no Listener.
This implicit Publisher will be deleted automatically when the following functions are called: DDS_DomainParticipant_delete_contained_entities, or DDS_DomainParticipant_delete_publisher with the implicit publisher as a parameter. Additionally, when a DomainParticipant is deleted, if there are no attached DataWriters that belong to the implicit Publisher, the implicit Publisher will be implicitly deleted.
| self | <<in>> Cannot be NULL. |
| DDS_Subscriber* DDS_DomainParticipant_get_implicit_subscriber | ( | DDS_DomainParticipant * | self | ) |
<<eXtension>> Returns the implicit DDS_Subscriber. If an implicit Subscriber does not already exist, this creates one.
There can only be one implicit Subscriber per DomainParticipant.
The implicit Subscriber is created with DDS_SUBSCRIBER_QOS_DEFAULT and no Listener.
This implicit Subscriber will be deleted automatically when the following functions are called: DDS_DomainParticipant_delete_contained_entities, or DDS_DomainParticipant_delete_subscriber with the subscriber as a parameter. Additionally, when a DomainParticipant is deleted, if there are no attached DataReaders that belong to the implicit Subscriber, the implicit Subscriber will be implicitly deleted.
| self | <<in>> Cannot be NULL. |
| DDS_ReturnCode_t DDS_DomainParticipant_ignore_participant | ( | DDS_DomainParticipant * | self, |
| const DDS_InstanceHandle_t * | handle | ||
| ) |
Instructs RTI Connext to locally ignore a remote DDS_DomainParticipant.
From the time of this call onwards, RTI Connext will locally behave as if the remote participant did not exist. This means it will ignore any topic, publication, or subscription that originates on that DDS_DomainParticipant.
There is no way to reverse this operation.
This operation can be used in conjunction with the discovery of remote participants offered by means of the DDS_ParticipantBuiltinTopicData to provide access control.
Application data can be associated with a DDS_DomainParticipant by means of the USER_DATA policy. This application data is propagated as a field in the built-in topic and can be used by an application to implement its own access control policy.
The DDS_DomainParticipant to ignore is identified by the handle argument. This handle is the one that appears in the DDS_SampleInfo retrieved when reading the data-samples available for the built-in DDS_DataReader to the DDS_DomainParticipant topic. The built-in DDS_DataReader is read with the same FooDataReader_read and FooDataReader_take operations used for any DDS_DataReader.
| self | <<in>> Cannot be NULL. |
| handle | <<in>> DDS_InstanceHandle_t of the DDS_DomainParticipant to be ignored. Cannot be NULL. |
| DDS_ReturnCode_t DDS_DomainParticipant_ignore_topic | ( | DDS_DomainParticipant * | self, |
| const DDS_InstanceHandle_t * | handle | ||
| ) |
Instructs RTI Connext to locally ignore a DDS_Topic.
This means it will locally ignore any publication, or subscription to the DDS_Topic.
There is no way to reverse this operation.
This operation can be used to save local resources when the application knows that it will never publish or subscribe to data under certain topics.
The DDS_Topic to ignore is identified by the handle argument. This is the handle of a DDS_Topic that appears in the DDS_SampleInfo retrieved when reading data samples from the built-in DDS_DataReader for the DDS_Topic.
| self | <<in>> Cannot be NULL. |
| handle | <<in>> Handle of the DDS_Topic to be ignored. Cannot be NULL. |
| DDS_ReturnCode_t DDS_DomainParticipant_ignore_publication | ( | DDS_DomainParticipant * | self, |
| const DDS_InstanceHandle_t * | handle | ||
| ) |
Instructs RTI Connext to locally ignore a publication.
A publication is defined by the association of a topic name, user data, and partition set on the DDS_Publisher (see DDS_PublicationBuiltinTopicData). After this call, any data written by that publication's DDS_DataWriter will be ignored.
This operation can be used to ignore local and remote DataWriters.
The publication (DataWriter) to ignore is identified by the handle argument.
handle can be obtained from the DDS_SampleInfo retrieved when reading data samples from the built-in DDS_DataReader for the publication topic. handle can be obtained by calling DDS_Entity_get_instance_handle for the local DataWriter. There is no way to reverse this operation.
| self | <<in>> Cannot be NULL. |
| handle | <<in>> Handle of the DDS_DataWriter to be ignored. Cannot be NULL. |
| DDS_ReturnCode_t DDS_DomainParticipant_ignore_subscription | ( | DDS_DomainParticipant * | self, |
| const DDS_InstanceHandle_t * | handle | ||
| ) |
Instructs RTI Connext to locally ignore a subscription.
A subscription is defined by the association of a topic name, user data, and partition set on the DDS_Subscriber (see DDS_SubscriptionBuiltinTopicData). After this call, any data received related to that subscription's DDS_DataReader will be ignored.
This operation can be used to ignore local and remote DataReaders.
The subscription to ignore is identified by the handle argument.
handle can be obtained from the DDS_SampleInfo retrieved when reading data samples from the built-in DDS_DataReader for the subscription topic. handle can be obtained by calling DDS_Entity_get_instance_handle for the local DataReader. There is no way to reverse this operation.
| self | <<in>> Cannot be NULL. |
| handle | <<in>> Handle of the DDS_DataReader to be ignored. Cannot be NULL. |
| DDS_DomainId_t DDS_DomainParticipant_get_domain_id | ( | DDS_DomainParticipant * | self | ) |
Get the unique domain identifier.
This operation retrieves the domain_id used to create the DDS_DomainParticipant. The domain_id identifies the DDS domain to which the DDS_DomainParticipant belongs. Each DDS domain represents a separate data 'communication plane' isolated from other domains.
| self | <<in>> Cannot be NULL. |
domainId that was used to create the domain | DDS_ReturnCode_t DDS_DomainParticipant_delete_contained_entities | ( | DDS_DomainParticipant * | self | ) |
Delete all the entities that were created by means of the "create" operations on the DDS_DomainParticipant.
This operation deletes all contained DDS_Publisher (including an implicit Publisher, if one exists), DDS_Subscriber (including implicit subscriber), DDS_Topic, DDS_ContentFilteredTopic, and DDS_MultiTopic objects.
Prior to deleting each contained entity, this operation will recursively call the corresponding delete_contained_entities operation on each contained entity (if applicable). This pattern is applied recursively. In this manner the operation delete_contained_entities() on the DDS_DomainParticipant will end up deleting all the entities recursively contained in the DDS_DomainParticipant, that is also the DDS_DataWriter, DDS_DataReader, as well as the DDS_QueryCondition and DDS_ReadCondition objects belonging to the contained DDS_DataReader.
The operation will fail with DDS_RETCODE_PRECONDITION_NOT_MET if any of the contained entities is in a state where it cannot be deleted.
If delete_contained_entities() completes successfully, the application may delete the DDS_DomainParticipant knowing that it has no contained entities.
| self | <<in>> Cannot be NULL. |
| DDS_ReturnCode_t DDS_DomainParticipant_assert_liveliness | ( | DDS_DomainParticipant * | self | ) |
Manually asserts the liveliness of this DDS_DomainParticipant.
This is used in combination with the DDS_LivelinessQosPolicy to indicate to RTI Connext that the entity remains active.
You need to use this operation if the DDS_DomainParticipant conatins DDS_DataWriter entities with the DDS_LivelinessQosPolicy::kind set to DDS_MANUAL_BY_PARTICIPANT_LIVELINESS_QOS and it only affects the liveliness of those DDS_DataWriter entities. Otherwise, it has no effect.
Note: writing data via the FooDataWriter_write or FooDataWriter_write_w_timestamp operation asserts liveliness on the DDS_DataWriter itself and its DDS_DomainParticipant. Consequently the use of assert_liveliness() is only needed if the application is not writing data regularly.
| self | <<in>> Cannot be NULL. |
| DDS_ReturnCode_t DDS_DomainParticipant_get_publishers | ( | DDS_DomainParticipant * | self, |
| struct DDS_PublisherSeq * | publishers | ||

| DDS_ReturnCode_t DDS_DomainParticipant_get_current_time | ( | DDS_DomainParticipant * | self, |
| struct DDS_Time_t * | current_time | ||
| ) |
Returns the current value of the time.
The current value of the time that RTI Connext uses to time-stamp DDS_DataWriter and to set the reception-timestamp for the data updates that it receives.
| self | <<in>> Cannot be NULL. |
| current_time | <<inout>> Current time to be filled up. Cannot be NULL. |
| DDS_Boolean DDS_DomainParticipant_contains_entity | ( | DDS_DomainParticipant * | self, |
| const DDS_InstanceHandle_t * | a_handle | ||
| ) |
Completes successfully with DDS_BOOLEAN_TRUE if the referenced DDS_Entity is contained by the DDS_DomainParticipant.
This operation checks whether or not the given a_handle represents an DDS_Entity that was created from the DDS_DomainParticipant. The containment applies recursively. That is, it applies both to entities (DDS_TopicDescription, DDS_Publisher, or DDS_Subscriber) created directly using the DDS_DomainParticipant as well as entities created using a contained DDS_Publisher, or DDS_Subscriber as the factory, and so forth.
The instance handle for an DDS_Entity may be obtained from built-in topic data, from various statuses, or from the operation DDS_Entity_get_instance_handle.
| self | <<in>> Cannot be NULL. |
| a_handle | <<in>> DDS_InstanceHandle_t of the DDS_Entity to be checked. |
| DDS_ReturnCode_t DDS_DomainParticipant_register_durable_subscription | ( | DDS_DomainParticipant * | self, |
| struct DDS_EndpointGroup_t * | group, | ||
| const char * | topic_name | ||
| ) |
Registers a Durable Subscription on the specified DDS_Topic on all Persistence Services.
If you need to receive all samples published on a DDS_Topic, including the ones published while a DDS_DataReader is inactive or before it may be created, create a Durable Subscription using this method.
In this way, the Persistence Service will ensure that all the samples on that DDS_Topic are retained until they are acknowledged by at least N DataReaders belonging to the Durable Subscription where N is the quorum count.
If the same Durable Subscription is created on a different DDS_Topic, the Persistence Service will implicitly delete the previous Durable Subscription and create a new one on the new DDS_Topic.
| self | <<in>> Cannot be NULL. |
| group | <<in>> DDS_EndpointGroup_t The Durable Subscription name and quorum. |
| topic_name | <<in>> The topic name for which the Durable Subscription is created. |
| DDS_ReturnCode_t DDS_DomainParticipant_delete_durable_subscription | ( | DDS_DomainParticipant * | self, |
| struct DDS_EndpointGroup_t * | group | ||
| ) |
Deletes an existing Durable Subscription on all Persistence Services.
The Persistence Service will delete the Durable Subscription and the quorum of the existing samples will be considered satisfied.
| self | <<in>> Cannot be NULL. |
| group | <<in>> DDS_EndpointGroup_t specifying the Durable Subscription name. Quorum is not required for this operation. |
| DDS_ReturnCode_t DDS_DomainParticipant_get_discovered_participants | ( | DDS_DomainParticipant * | self, |
| struct DDS_InstanceHandleSeq * | participant_handles | ||
| ) |
Returns list of discovered DDS_DomainParticipant s.
This operation retrieves the list of DDS_DomainParticipant s that have been discovered in the domain and that the application has not indicated should be "ignored" by means of the DDS_DomainParticipant_ignore_participant operation.
| self | <<in>> Cannot be NULL. |
| participant_handles | <<inout>> DDS_InstanceHandleSeq to be filled with handles of the discovered DDS_DomainParticipant s |
| DDS_ReturnCode_t DDS_DomainParticipant_get_discovered_participant_data | ( | DDS_DomainParticipant * | self, |
| struct DDS_ParticipantBuiltinTopicData * | participant_data, | ||
| const DDS_InstanceHandle_t * | participant_handle | ||
| ) |
Returns DDS_ParticipantBuiltinTopicData for the specified DDS_DomainParticipant .
This operation retrieves information on a DDS_DomainParticipant that has been discovered on the network. The participant must be in the same domain as the participant on which this operation is invoked and must not have been "ignored" by means of the DDS_DomainParticipant_ignore_participant operation.
The participant_handle must correspond to such a DomainParticipant. Otherwise, the operation will fail with PRECONDITION_NOT_MET.
Use the operation DDS_DomainParticipant_get_discovered_participants to find the DDS_DomainParticipant s that are currently discovered.
Note: This operation does not retrieve the DDS_ParticipantBuiltinTopicData::property. This information is available through DDS_DataReaderListener::on_data_available() (if a reader listener is installed on the DDS_ParticipantBuiltinTopicDataDataReader).
| self | <<in>> Cannot be NULL. |
| participant_data | <<inout>> DDS_ParticipantBuiltinTopicData to be filled with the specified DDS_DomainParticipant 's data. |
| participant_handle | <<in>> DDS_InstanceHandle_t of DDS_DomainParticipant. |

| struct DDS_TopicBuiltinTopicData * | topic_data, | ||
| const DDS_InstanceHandle_t * | topic_handle | ||
| ) |
Returns DDS_TopicBuiltinTopicData for the specified DDS_Topic.
This operation retrieves information on a DDS_Topic that has been discovered by the local Participant and must not have been "ignored" by means of the DDS_DomainParticipant_ignore_topic operation.
The topic_handle must correspond to such a topic. Otherwise, the operation will fail with DDS_RETCODE_PRECONDITION_NOT_MET.
This call is not supported for remote topics. If a remote topic_handle is used, the operation will fail with DDS_RETCODE_UNSUPPORTED.
Use the operation DDS_DomainParticipant_get_discovered_topics to find the topics that are currently discovered.
| self | <<in>> Cannot be NULL. |
| topic_data | <<inout>> DDS_TopicBuiltinTopicData to be filled with the specified DDS_Topic's data. |

| DDS_ReturnCode_t DDS_DomainParticipant_add_peer | ( | DDS_DomainParticipant * | self, |
| const char * | peer_desc_string | ||
| ) |
<<eXtension>> Attempt to contact one or more additional peer participants.
Add the given peer description to the list of peers with which this DDS_DomainParticipant will try to communicate.
This function may be called at any time after this DDS_DomainParticipant has been created (before or after it has been enabled).
If this function is called after DDS_Entity_enable, an attempt will be made to contact the new peer(s) immediately.
If this function is called before the DomainParticipant is enabled, the peer description will simply be added to the list that was populated by DDS_DiscoveryQosPolicy::initial_peers; the first attempted contact will take place after this DDS_DomainParticipant is enabled.
Adding a peer description with this function does not guarantee that any peer(s) discovered as a result will exactly correspond to those described:
To be informed of the exact remote participants that are discovered, regardless of which peers this DDS_DomainParticipant attempts to discover, use the built-in participant topic: DDS_PARTICIPANT_TOPIC_NAME.
To remove specific peer locators, you may use DDS_DomainParticipant_remove_peer. If a peer is removed, the add_peer operation will add it back to the list of peers.
To stop communicating with a peer DDS_DomainParticipant that has been discovered, use DDS_DomainParticipant_ignore_participant.
Adding a peer description with this function has no effect on the DDS_DiscoveryQosPolicy::initial_peers that may be subsequently retrieved with DDS_DomainParticipant_get_qos() (because DDS_DiscoveryQosPolicy is immutable).
| self | <<in>> Cannot be NULL. |
| peer_desc_string | <<in>> New peer descriptor to be added. The format is specified in Peer Descriptor Format. Cannot be NULL. |
| DDS_ReturnCode_t DDS_DomainParticipant_remove_peer | ( | DDS_DomainParticipant * | self, |
| const char * | peer_desc_string | ||
| ) |
<<eXtension>> Remove one or more peer participants from the list of peers with which this DDS_DomainParticipant will try to communicate.
This function may be called any time after this DDS_DomainParticipant has been enabled
Calling this function has the following effects:
If remote participants located on a peer that was previously removed are discovered, they will be ignored untill the related peer is added back by using DDS_DomainParticipant_add_peer.
Removing a peer description with this function has no effect on the DDS_DiscoveryQosPolicy::initial_peers that may be subsequently retrieved with DDS_DomainParticipant_get_qos() (because DDS_DiscoveryQosPolicy is immutable).
| self | <<in>> Cannot be NULL. |
| peer_desc_string | <<in>> Peer descriptor to be removed. The format is specified in Peer Descriptor Format. Cannot be NULL. |
| DDS_ReturnCode_t DDS_DomainParticipant_set_qos | ( | DDS_DomainParticipant * | self, |
| const struct DDS_DomainParticipantQos * | qos | ||
| ) |
Change the QoS of this DomainParticipant.
The DDS_DomainParticipantQos::user_data and DDS_DomainParticipantQos::entity_factory can be changed. The other policies are immutable.
| self | <<in>> Cannot be NULL. |
| qos | <<in>> Set of policies to be applied to DDS_DomainParticipant. Policies must be consistent. Immutable policies cannot be changed after DDS_DomainParticipant is enabled. The special value DDS_PARTICIPANT_QOS_DEFAULT can be used to indicate that the QoS of the DDS_DomainParticipant should be changed to match the current default DDS_DomainParticipantQos set in the DDS_DomainParticipantFactory. Cannot be NULL. |
| DDS_ReturnCode_t DDS_DomainParticipant_set_qos_with_profile | ( | DDS_DomainParticipant * | self, |
| const char * | library_name, | ||
| const char * | profile_name | ||
| ) |
<<eXtension>> Change the QoS of this domain participant using the input XML QoS profile.
The DDS_DomainParticipantQos::user_data and DDS_DomainParticipantQos::entity_factory can be changed. The other policies are immutable.
| self | <<in>> Cannot be NULL. |
| library_name | <<in>> Library name containing the XML QoS profile. If library_name is null RTI Connext will use the default library (see DDS_DomainParticipantFactory_set_default_library). |
| profile_name | <<in>> XML QoS Profile name. If profile_name is null RTI Connext will use the default profile (see DDS_DomainParticipantFactory_set_default_profile). |
| DDS_ReturnCode_t DDS_DomainParticipant_get_qos | ( | DDS_DomainParticipant * | self, |
| struct DDS_DomainParticipantQos * | qos | ||
| ) |
Get the participant QoS.
This function may potentially allocate memory depending on the sequences contained in some QoS policies.
| DDS_ReturnCode_t DDS_DomainParticipant_set_listener | ( | DDS_DomainParticipant * | self, |
| const struct DDS_DomainParticipantListener * | l, | ||
| DDS_StatusMask | mask | ||
| ) |
Sets the participant listener.
| self | <<in>> Cannot be NULL. |
| l | <<in>> Listener to be installed on entity. |
| mask | <<in>> Changes of communication status to be invoked on the listener. See DDS_StatusMask. The callback function on the listener cannot be NULL if the corresponding status is turned on in the mask. |
Once a participant has been enabled, it is therefore important that the listener not be changed unless some application-specific means are available of ensuring that the old listener cannot be concurrently in use. If this contract is violated, it is possible for the DDS_Listener::listener_data field to have been changed without the callback function pointers having been changed (or vica versa); callback functions may therefore be passed an incorrect DDS_Listener::listener_data value.

Get the participant listener.
| self | <<in>> Cannot be NULL. |
| DDS_ReturnCode_t DDS_DomainParticipant_get_listenerX | ( | DDS_DomainParticipant * | self, |

| ) |
<<eXtension>> Get the participant listener.
An alternative form of DDS_DomainParticipant_get_listener that fills in an existing listener structure rather than returning one on the stack.
| DDS_Publisher* DDS_DomainParticipant_lookup_publisher_by_name_exp | ( | DDS_DomainParticipant * | self, |
| const char * | publisher_name | ||
| ) |
<<experimental>> <<eXtension>> Looks up a DDS_Publisher by its entity name within this DDS_DomainParticipant.
Every DDS_Publisher in the system has an entity name which is configured and stored in the GROUP_DATA policy. The use of the GROUP_DATA to store the entity name is a temporary situation while the feature is in experimental state.
This operation retrieves a DDS_Publisher within the DDS_DomainParticipant given the entity's name. If there are several DDS_Publisher with the same name within the DDS_DomainParticipant, this function returns the first matching occurrence.
| self | <<in>> Cannot be NULL. |
| publisher_name | <<in>> Entity name of the DDS_Publisher. |
| DDS_Subscriber* DDS_DomainParticipant_lookup_subscriber_by_name_exp | ( | DDS_DomainParticipant * | self, |

| ) |
<<experimental>> <<eXtension>> Retrieves a DDS_Subscriber by its entity name within this DDS_DomainParticipant.
Every DDS_Subscriber in the system has an entity name which is configured and stored in the GROUP_DATA policy. The use of the GROUP_DATA to store the entity name is a temporary situation while the function is in experimental state.
This operation retrieves a DDS_Subscriber within the DDS_DomainParticipant given the entity's name. If there are several DDS_Subscriber with the same name within the DDS_DomainParticipant, this function returns the first matching occurrence.
| self | <<in>> Cannot be NULL. |
| subscriber_name | <<in>> Entity name of the DDS_Subscriber. |
| DDS_DataWriter* DDS_DomainParticipant_lookup_datawriter_by_name_exp | ( | DDS_DomainParticipant * | self, |

<<experimental>> <<eXtension>> Looks up a DDS_DataWriter by its entity name within this DDS_DomainParticipant.
Every DDS_DataWriter in the system has an entity name which is configured and stored in the EntityName policy, ENTITY_NAME.
Every DDS_Publisher in the system has an entity name which is configured and stored in the <<eXtension>> GROUP_DATA policy. This is a temporary situation situation while the function is in experimental state.
This operation retrieves a DDS_DataWriter within a DDS_Publisher given the specified name which encodes both to the DDS_DataWriter and the DDS_Publisher name.
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_Publisher to which the DDS_DataWriter belongs and the entity name of of the DDS_DataWriter itself, separated by a double colon "::". For example: MyPublisherName::MyDataWriterName
The plain name contains the DDS_DataWriter name only. In this situation it is implied that the DDS_DataWriter belongs to the implicit DDS_Publisher so the use of a plain name is equivalent to specifying a fully qualified name with the DDS_Publisher name part being "implicit". For example: the plain name "MyDataWriterName" is equivalent to specifiying the fully qualified name "implicit::MyDataWriterName"
The DDS_DataWriter is only looked up within the DDS_Publisher specified in the fully qualified name, or within the implicit DDS_Publisher if the name was not fully qualified.
If there are several DDS_DataWriter with the same name within the corresponding DDS_Publisher this function returns the first matching occurrence.
| self | <<in>> Cannot be NULL. |
| datawriter_full_name | <<in>> Entity name or fully-qualified entity name of the DDS_DataWriter. |

This operation retrieves a DDS_DataReader within a DDS_Subscriber given the specified name which encodes both to the DDS_DataReader and the DDS_Subscriber name.
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_Subscriber to which the DDS_DataReader belongs and the entity name of of the DDS_DataReader itself, separated by a double colon "::". For example: MySubscriberName::MyDataReaderName
The plain name contains the DDS_DataReader name only. In this situation it is implied that the DDS_DataReader belongs to the implicit DDS_Subscriber so the use of a plain name is equivalent to specifying a fully qualified name with the DDS_Subscriber name part being "implicit". For example: the plain name "MyDataReaderName" is equivalent to specifiying the fully qualified name "implicit::MyDataReaderName"
The DDS_DataReader is only looked up within the DDS_Subscriber specified in the fully qualified name, or within the implicit DDS_Subscriber if the name was not fully qualified.
If there are several DDS_DataReader with the same name within the corresponding DDS_Subscriber this function returns the first matching occurrence.
| self | <<in>> Cannot be NULL. |
| datareader_full_name | <<in>> Full entity name of the DDS_DataReader. |
