Detailed Description

<<singleton>> <<interface>> Allows creation and destruction of DDSDomainParticipant objects.

The sole purpose of this class is to allow the creation and destruction of DDSDomainParticipant objects. This class itself is a <<singleton>>, and accessed via the get_instance() method, and destroyed with finalize_instance() method.

A single application can participate in multiple domains by instantiating multiple DDSDomainParticipant objects.

An application may even instantiate multiple participants in the same domain. Participants in the same domain exchange data in the same way regardless of whether they are in the same application or different applications or on the same node or different nodes; their location is transparent.

There are two important caveats:

• When there are multiple participants on the same node (in the same application or different applications) in the same domain, the application(s) must make sure that the participants do not try to bind to the same port numbers. You must disambiguate between the participants by setting a participant ID for each participant (). The port numbers used by a participant are calculated based on both the participant index and the domain ID, so if all participants on the same node have different participant indexes, they can coexist in the same domain.
• You cannot mix entities from different participants. For example, you cannot delete a topic on a different participant than you created it from, and you cannot ask a subscriber to create a reader for a topic created from a participant different than the subscriber's own participant. (Note that it is permissable for an application built on top of RTI Data Distribution Service to know about entities from different participants. For example, an application could keep references to a reader from one domain and a writer from another and then bridge the domains by writing the data received in the reader callback.)

static DDSDomainParticipantFactory* DDSDomainParticipantFactory::get_instance

(

)

[static]

Gets the singleton instance of this class.

MT Safety:

On non-Linux systems: UNSAFE for multiple threads to simultaneously make the FIRST call to either DDSDomainParticipantFactory::get_instance() or DDSDomainParticipantFactory::finalize_instance(). Subsequent calls are thread safe. (On Linux systems, these calls are thread safe.)

DDS_TheParticipantFactory can be used as an alias for the singleton factory returned by this operation.

Returns:

The singleton DDSDomainParticipantFactory instance.

DDS_TheParticipantFactory

static DDS_ReturnCode_t DDSDomainParticipantFactory::finalize_instance

(

)

[static]

<<eXtension>> Destroys the singleton instance of this class.

Only necessary to explicitly reclaim resources used by the participant factory singleton. Note that on many OSs, these resources are automatically reclaimed by the OS when the program terminates. However, some memory-check tools still flag these as unreclaimed. So this method provides a way to clean up memory used by the participant factory.

Precondition:

All participants created from the factory have been deleted.

Postcondition:

All resources belonging to the factory have been reclaimed. Another call to DDSDomainParticipantFactory::get_instance will return a new lifecycle of the singleton.

MT Safety:

On non-Linux systems: UNSAFE for multiple threads to simultaneously make the FIRST call to either DDSDomainParticipantFactory::get_instance() or DDSDomainParticipantFactory::finalize_instance(). Subsequent calls are thread safe. (On Linux systems, these calls are thread safe.)

Returns:

One of the Standard Return Codes, or DDS_RETCODE_PRECONDITION_NOT_MET

virtual DDS_ReturnCode_t DDSDomainParticipantFactory::set_default_participant_qos

(

const DDS_DomainParticipantQos &

qos

)

[pure virtual]

Sets the default DDS_DomainParticipantQos values for this domain participant factory.

This method may potentially allocate memory depending on the sequences contained in some QoS policies.

MT Safety:

UNSAFE. It is not safe to retrieve the default QoS value from a domain participant factory while another thread may be simultaneously calling DDSDomainParticipantFactory::set_default_participant_qos

Parameters:

qos

<<inout>> Qos to be filled up. The special value DDS_PARTICIPANT_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 DDSDomainParticipantFactory::set_default_participant_qos had never been called.

Returns:

One of the Standard Return Codes

DDSDomainParticipantFactory::create_participant

virtual DDS_ReturnCode_t DDSDomainParticipantFactory::set_default_participant_qos_with_profile	(	const char *	library_name,
		const char *	profile_name
	)			[pure virtual]

<<eXtension>> Sets the default DDS_DomainParticipantQos values for this domain participant factory based on the input XML QoS profile.

This method may potentially allocate memory depending on the sequences contained in some QoS policies.

This default value will be used for newly created DDSDomainParticipant if DDS_PARTICIPANT_QOS_DEFAULT is specified as the qos parameter when DDSDomainParticipantFactory::create_participant is called.

Precondition:

The DDS_DomainParticipantQos contained in the specified XML QoS profile must be consistent, or else the operation will have no effect and fail with DDS_RETCODE_INCONSISTENT_POLICY

MT Safety:

UNSAFE. It is not safe to retrieve the default QoS value from a domain participant factory while another thread may be simultaneously calling DDSDomainParticipantFactory::set_default_participant_qos

Parameters:

	library_name	<<in>> Library name containing the XML QoS profile. If library_name is null RTI Data Distribution Service will use the default library (see DDSDomainParticipantFactory::set_default_library).
	profile_name	<<in>> XML QoS Profile name. If profile_name is null RTI Data Distribution Service will use the default profile (see DDSDomainParticipantFactory::set_default_profile).

If the input profile cannot be found the method fails with DDS_RETCODE_ERROR.

Returns:

One of the Standard Return Codes, or DDS_RETCODE_INCONSISTENT_POLICY

DDS_PARTICIPANT_QOS_DEFAULT

DDSDomainParticipantFactory::create_participant_with_profile

virtual DDS_ReturnCode_t DDSDomainParticipantFactory::get_default_participant_qos

(

DDS_DomainParticipantQos &

qos

)

[pure virtual]

Initializes the DDS_DomainParticipantQos instance with default values.

The retrieved qos will match the set of values specified on the last successful call to DDSDomainParticipantFactory::set_default_participant_qos, or DDSDomainParticipantFactory::set_default_participant_qos_with_profile, or else, if the call was never made, the default values listed in DDS_DomainParticipantQos.

This method may potentially allocate memory depending on the sequences contained in some QoS policies.

Parameters:

qos

<<out>> the domain participant's QoS

MT Safety:

UNSAFE. It is not safe to retrieve the default QoS value from a domain participant factory while another thread may be simultaneously calling DDSDomainParticipantFactory::set_default_participant_qos

Returns:

One of the Standard Return Codes

virtual DDS_ReturnCode_t DDSDomainParticipantFactory::set_default_library

(

const char *

library_name

)

[pure virtual]

<<eXtension>> Sets the default XML library for a DDSDomainParticipantFactory.

Any API requiring a library_name as a parameter can use null to refer to the default library.

See also:

DDSDomainParticipantFactory::set_default_profile for more information.

Parameters:

library_name

<<in>> Library name. If library_name is null any previous default is unset.

Returns:

One of the Standard Return Codes

See also:

DDSDomainParticipantFactory::get_default_library

virtual const char* DDSDomainParticipantFactory::get_default_library

(

)

[pure virtual]

<<eXtension>> Gets the default XML library associated with a DDSDomainParticipantFactory.

Returns:

The default library or null if the default library was not set.

See also:

DDSDomainParticipantFactory::set_default_library

virtual DDS_ReturnCode_t DDSDomainParticipantFactory::set_default_profile	(	const char *	library_name,
		const char *	profile_name
	)			[pure virtual]

<<eXtension>> Sets the default XML profile for a DDSDomainParticipantFactory.

This method specifies the profile that will be used as the default the next time a default DomainParticipantFactory profile is needed during a call to a DomainParticipantFactory method. When calling a DDSDomainParticipantFactory method 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.)

This method does not set the default QoS for newly created DomainParticipants; for this functionality, use DDSDomainParticipantFactory::set_default_participant_qos_with_profile (you may pass in NULL after having called set_default_profile()).

Parameters:

	library_name	<<in>> The library name containing the profile.
	profile_name	<<in>> The profile name. If profile_name is null any previous default is unset.

Returns:

One of the Standard Return Codes

	)			[pure virtual]

Creates a new DDSDomainParticipant object.

Precondition:

The specified QoS policies must be consistent or the operation will fail and no DDSDomainParticipant will be created.

If you want to create multiple participants on a given host in the same domain, make sure each one has a different participant index (set in the DDS_WireProtocolQosPolicy). This in turn will ensure each participant uses a different port number (since the unicast port numbers are calculated from the participant index and the domain ID).

Note that if there is a single participant per host in a given domain, the participant index can be left at the default value (-1).

Parameters:

	domainId	<<in>> ID of the domain that the application intends to join. [range] [>=0], and does not violate guidelines stated in DDS_RtpsWellKnownPorts_t.
	qos	<<in>> the DomainParticipant's QoS. The special value DDS_PARTICIPANT_QOS_DEFAULT can be used to indicate that the DDSDomainParticipant should be created with the default DDS_DomainParticipantQos set in the DDSDomainParticipantFactory.
	listener	<<in>> the domain participant's listener.
	mask	<<in>>. Changes of communication status to be invoked on the listener.

Returns:

<<in>> Set of policies to be applied to DDSDomainParticipantFactory. Policies must be consistent. Immutable policies can only be changed before calling any other RTI Data Distribution Service methods except for DDSDomainParticipantFactory::get_qos

Returns:

One of the Standard Return Codes, DDS_RETCODE_IMMUTABLE_POLICY if immutable policy is changed, or DDS_RETCODE_INCONSISTENT_POLICY if policies are inconsistent

virtual DDS_ReturnCode_t DDSDomainParticipantFactory::get_qos

(

DDS_DomainParticipantFactoryQos &

qos

)

[pure virtual]

Gets the value for participant factory QoS.

Parameters:

qos

<<inout>> QoS to be filled up.

Returns:

One of the Standard Return Codes

virtual DDS_ReturnCode_t DDSDomainParticipantFactory::load_profiles

(

)

[pure virtual]

<<eXtension>> Loads the XML QoS profiles.

The XML QoS profiles are loaded implicitly after the first DDSDomainParticipant is created or explicitly, after a call to this method.

This has the same effect as DDSDomainParticipantFactory::reload_profiles().

Returns:

One of the Standard Return Codes

virtual DDS_ReturnCode_t DDSDomainParticipantFactory::unload_profiles

(

)

[pure virtual]

<<eXtension>> Unloads the XML QoS profiles.

The resources associated with the XML QoS profiles are freed. Any reference to the profiles after calling this method will fail with an error.

Returns:

One of the Standard Return Codes

virtual DDS_ReturnCode_t DDSDomainParticipantFactory::unregister_thread

(

)

[pure virtual]

<<eXtension>> Allows the user to release thread specific resources kept by the middleware.

This function should be called by the user right before exiting a thread where DDS API were used. In this way the middleware will be able to free all the resources related to this specific thread. The best approach is to call the function during the thread deletion after all the DDS related API have have been called.

Returns:

One of the Standard Return Codes
