get_default_participant_qos(*args)¶

Overload 1:

This operation retrieves the default value of the DomainParticipant QoS, that is, the QoS policies which will be used for newly created DomainParticipant entities in the case where the QoS policies are defaulted in the create_participant operation. The values retrieved get_default_participant_qos will match the set of values specified on the last successful call to set_default_participant_qos, or else, if the call was never made, the default values.

Parameters: qos (DomainParticipantQos) – DomainParticipantQos where the qos is returned
Return type: ReturnCode_t
Returns: RETCODE_OK

Overload 2:

This operation retrieves the default value of the DomainParticipant QoS, that is, the QoS policies which will be used for newly created DomainParticipant entities in the case where the QoS policies are defaulted in the create_participant operation. The values retrieved get_default_participant_qos will match the set of values specified on the last successful call to set_default_participant_qos, or else, if the call was never made, the default values.

Return type: DomainParticipantQos
Returns: A reference to the default DomainParticipantQos

static get_instance()¶

Returns the DomainParticipantFactory singleton instance.

Return type: DomainParticipantFactory
Returns: A raw pointer to the DomainParticipantFactory singleton instance.

get_participant_qos_from_profile(profile_name, qos)¶

Fills the DomainParticipantQos with the values of the XML profile.

Parameters

profile_name (string) – DomainParticipant profile name.
qos (DomainParticipantQos) – DomainParticipantQos object where the qos is returned.

Return type

ReturnCode_t

Returns

RETCODE_OK if the profile exists. RETCODE_BAD_PARAMETER otherwise.

get_qos(qos)¶

This operation returns the value of the DomainParticipantFactory QoS policies.

Parameters: qos (DomainParticipantFactoryQos) – DomaParticipantFactoryQos reference where the qos is returned
Return type: ReturnCode_t
Returns: RETCODE_OK

static get_shared_instance()¶

Returns the DomainParticipantFactory singleton instance.

Return type: std::shared_ptr< eprosima::fastdds::dds::DomainParticipantFactory >
Returns: A shared pointer to the DomainParticipantFactory singleton instance.

load_XML_profiles_file(xml_profile_file)¶

Load profiles from XML file.

Parameters: xml_profile_file (string) – XML profile file.
Return type: ReturnCode_t
Returns: RETCODE_OK if it is correctly loaded, RETCODE_ERROR otherwise.

load_XML_profiles_string(data, length)¶

Load profiles from XML string.

Parameters

data (string) – buffer containing xml data.
length (int) – length of data

Return type

ReturnCode_t

Returns

RETCODE_OK if it is correctly loaded, RETCODE_ERROR otherwise.

load_profiles()¶

Load profiles from default XML file.

Return type: ReturnCode_t
Returns: RETCODE_OK

lookup_participant(domain_id)¶

This operation retrieves a previously created DomainParticipant belonging to specified domain_id. If no such DomainParticipant exists, the operation will return ‘nullptr’. If multiple DomainParticipant entities belonging to that domain_id exist, then the operation will return one of them. It is not specified which one.

Parameters: domain_id (int) –
Return type: DomainParticipant
Returns: previously created DomainParticipant within the specified domain

lookup_participants(domain_id)¶

Returns all participants that belongs to the specified domain_id.

Parameters: domain_id (int) –
Return type: std::vector< eprosima::fastdds::dds::DomainParticipant *,std::allocator< eprosima::fastdds::dds::DomainParticipant * > >
Returns: previously created DomainParticipants within the specified domain

set_default_participant_qos(qos)¶

This operation sets a default value of the DomainParticipant QoS policies which will be used for newly created DomainParticipant entities in the case where the QoS policies are defaulted in the create_participant operation.

This operation will check that the resulting policies are self consistent; if they are not, the operation will have no effect and return INCONSISTENT_POLICY.

The special value PARTICIPANT_QOS_DEFAULT may be passed to this operation to indicate that the default QoS should be reset back to the initial values the factory would use, that is the values that would be used if the set_default_participant_qos operation had never been called.

Parameters: qos (DomainParticipantQos) – DomainParticipantQos to be set
Return type: ReturnCode_t
Returns: RETCODE_INCONSISTENT_POLICY if the Qos is not self consistent and RETCODE_OK if the qos is changed correctly.

set_qos(qos)¶

This operation sets the value of the DomainParticipantFactory QoS policies. These policies control the behavior of the object a factory for entities.

Note that despite having QoS, the DomainParticipantFactory is not an Entity.

This operation will check that the resulting policies are self consistent; if they are not, the operation will have no effect and return INCONSISTENT_POLICY.

Parameters: qos (DomainParticipantFactoryQos) – DomainParticipantFactoryQos to be set.
Return type: ReturnCode_t
Returns: RETCODE_IMMUTABLE_POLICY if any of the Qos cannot be changed, RETCODE_INCONSISTENT_POLICY if the Qos is not self consistent and RETCODE_OK if the qos is changed correctly.
