Detailed Description

<<singleton>> <<interface>> Allows creation and destruction of com.rti.dds.domain.DomainParticipant objects.

The sole purpose of this class is to allow the creation and destruction of com.rti.dds.domain.DomainParticipant 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 com.rti.dds.domain.DomainParticipant 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 (com.rti.dds.infrastructure.WireProtocolQosPolicy.participant_id). 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 Connext 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 final DomainParticipantFactory 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 com.rti.dds.domain.DomainParticipantFactory.get_instance() or com.rti.dds.domain.DomainParticipantFactory.finalize_instance(). Subsequent calls are thread safe. (On Linux systems, these calls are thread safe.)

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

Returns:

The singleton com.rti.dds.domain.DomainParticipantFactory instance.

DomainParticipantFactory.TheParticipantFactory

static final void 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 com.rti.dds.domain.DomainParticipantFactory.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 com.rti.dds.domain.DomainParticipantFactory.get_instance() or com.rti.dds.domain.DomainParticipantFactory.finalize_instance(). Subsequent calls are thread safe. (On Linux systems, these calls are thread safe.)

Exceptions:

of the Standard Return Codes, or RETCODE_PRECONDITION_NOT_MET

abstract DomainParticipant create_participant	(	int	domainId,
		DomainParticipantQos	qos,
		DomainParticipantListener	listener,
		int	mask
	)			[pure virtual]

Creates a new com.rti.dds.domain.DomainParticipant object.

Precondition:

The specified QoS policies must be consistent or the operation will fail and no com.rti.dds.domain.DomainParticipant 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 com.rti.dds.infrastructure.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 com.rti.dds.infrastructure.RtpsWellKnownPorts_t.
	qos	<<in>> the DomainParticipant's QoS. The special value DomainParticipantFactory.PARTICIPANT_QOS_DEFAULT can be used to indicate that the com.rti.dds.domain.DomainParticipant should be created with the default com.rti.dds.domain.DomainParticipantQos set in the com.rti.dds.domain.DomainParticipantFactory. Cannot be NULL.
	listener	<<in>> the domain participant's listener.
	mask	<<in>>. Changes of communication status to be invoked on the listener.

Returns:

domain participant or NULL on failure

abstract void delete_participant

(

DomainParticipant

a_participant

)

[pure virtual]

Deletes an existing com.rti.dds.domain.DomainParticipant.

Precondition:

All domain entities belonging to the participant must have already been deleted. Otherwise it fails with the error RETCODE_PRECONDITION_NOT_MET.

Postcondition:

Listener installed on the com.rti.dds.domain.DomainParticipant will not be called after this method returns successfully.

Parameters:

abstract void get_default_participant_qos

(

DomainParticipantQos

qos

)

[pure virtual]

Initializes the com.rti.dds.domain.DomainParticipantQos instance with default values.

The retrieved qos will match the set of values specified on the last successful call to com.rti.dds.domain.DomainParticipantFactory.set_default_participant_qos, or com.rti.dds.domain.DomainParticipantFactory.set_default_participant_qos_with_profile, or else, if the call was never made, the default values listed in com.rti.dds.domain.DomainParticipantQos.

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

Parameters:

qos

<<out>> the domain participant's QoS Cannot be NULL.

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 com.rti.dds.domain.DomainParticipantFactory.set_default_participant_qos

Exceptions:

One

abstract void set_default_participant_qos

(

DomainParticipantQos

qos

)

[pure virtual]

Sets the default com.rti.dds.domain.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 com.rti.dds.domain.DomainParticipantFactory.set_default_participant_qos

Parameters:

qos

<<inout>> Qos to be filled up. The special value DomainParticipantFactory.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 com.rti.dds.domain.DomainParticipantFactory.set_default_participant_qos had never been called. Cannot be NULL.

Exceptions:

One

abstract void set_default_participant_qos_with_profile	(	String	library_name,
		String	profile_name
	)			[pure virtual]

<<eXtension>> Sets the default com.rti.dds.domain.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 com.rti.dds.domain.DomainParticipant if DomainParticipantFactory.PARTICIPANT_QOS_DEFAULT is specified as the qos parameter when com.rti.dds.domain.DomainParticipantFactory.create_participant is called.

Precondition:

The com.rti.dds.domain.DomainParticipantQos contained in the specified XML QoS profile must be consistent, or else the operation will have no effect and fail with 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 com.rti.dds.domain.DomainParticipantFactory.set_default_participant_qos

Parameters:

	library_name	<<in>> Library name containing the XML QoS profile. If library_name is null RTI Connext will use the default library (see com.rti.dds.domain.DomainParticipantFactory.set_default_library).
	profile_name	<<in>> XML QoS Profile name. If profile_name is null RTI Connext will use the default profile (see com.rti.dds.domain.DomainParticipantFactory.set_default_profile).

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

Exceptions:

One

(

int

domainId

)

[pure virtual]

Locates an existing com.rti.dds.domain.DomainParticipant.

If no such com.rti.dds.domain.DomainParticipant exists, the operation will return NULL value.

If multiple com.rti.dds.domain.DomainParticipant entities belonging to that domainId exist, then the operation will return one of them. It is not specified which one.

Parameters:

domainId

<<in>> ID of the domain participant to lookup.

Returns:

domain participant if it exists, or NULL

abstract void get_qos

abstract void set_qos

(

DomainParticipantFactoryQos

qos

)

[pure virtual]

Sets the value for a participant factory QoS.

The com.rti.dds.domain.DomainParticipantFactoryQos.entity_factory can be changed. The other policies are immutable.

Note that despite having QoS, the com.rti.dds.domain.DomainParticipantFactory is not an com.rti.dds.infrastructure.Entity.

Parameters:

qos

<<in>> Set of policies to be applied to com.rti.dds.domain.DomainParticipantFactory. Policies must be consistent. Immutable policies can only be changed before calling any other RTI Connext methods except for com.rti.dds.domain.DomainParticipantFactory.get_qos Cannot be NULL.

See also:

com.rti.dds.domain.DomainParticipantFactory.set_default_profile

abstract void set_default_profile	(	String	library_name,
		String	profile_name
	)			[pure virtual]

<<eXtension>> Sets the default XML profile for a com.rti.dds.domain.DomainParticipantFactory.

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 com.rti.dds.domain.DomainParticipantFactory 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 com.rti.dds.domain.DomainParticipantFactory.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.

Exceptions:

One

abstract String get_default_profile_library

(

)

[pure virtual]

<<eXtension>> Gets the library where the default XML profile is contained for a com.rti.dds.domain.DomainParticipantFactory.

The default profile library is automatically set when com.rti.dds.domain.DomainParticipantFactory.set_default_profile is called.

This library can be different than the com.rti.dds.domain.DomainParticipantFactory default library (see com.rti.dds.domain.DomainParticipantFactory.get_default_library).

Returns:

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

abstract void get_qos_profile_libraries

(

StringSeq

library_names

)

[pure virtual]

<<eXtension>> Gets the names of all XML QoS profile libraries associated with the com.rti.dds.domain.DomainParticipantFactory

Parameters:

library_names

<<out>> com.rti.dds.infrastructure.StringSeq to be filled with names of XML QoS profile libraries. Cannot be NULL.

abstract void get_qos_profiles	(	StringSeq	profile_names,
		String	library_name
	)			[pure virtual]

<<eXtension>> Gets the names of all XML QoS profiles associated with the input XML QoS profile library.

Parameters:

	profile_names	<<out>> com.rti.dds.infrastructure.StringSeq to be filled with names of XML QoS profiles. 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 com.rti.dds.domain.DomainParticipantFactory.set_default_library).

abstract DomainParticipant create_participant_with_profile	(	int	domainId,
		String	library_name,
		String	profile_name,
		DomainParticipantListener	listener,
		int	mask
	)			[pure virtual]

<<eXtension>> Creates a new com.rti.dds.domain.DomainParticipant object using the com.rti.dds.domain.DomainParticipantQos associated with the input XML QoS profile.

Precondition:

The com.rti.dds.domain.DomainParticipantQos in the input profile must be consistent, or the operation will fail and no com.rti.dds.domain.DomainParticipant 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 com.rti.dds.infrastructure.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 com.rti.dds.infrastructure.RtpsWellKnownPorts_t.
	library_name	<<in>> Library name containing the XML QoS profile. If library_name is null RTI Connext will use the default library (see com.rti.dds.domain.DomainParticipantFactory.set_default_library).
	profile_name	<<in>> XML QoS Profile name. If profile_name is null RTI Connext will use the default profile (see com.rti.dds.domain.DomainParticipantFactory.set_default_profile).
	listener	<<in>> the DomainParticipant's listener.
	mask	<<in>>. Changes of communication status to be invoked on the listener.

Returns:

domain participant or NULL on failure

abstract void 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.
