 Gets the singleton instance of this class.

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


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:

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.
See also:
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

DDS_PARTICIPANT_QOS_DEFAULT

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

DDSDomainParticipantFactory::create_participant

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

DDSDomainParticipantFactory::set_default_profile

virtual const char* DDSDomainParticipantFactory::get_default_profile_library (  )  [pure virtual]

<<eXtension>> Gets the library where the default XML profile is contained for a DDSDomainParticipantFactory.

This library can be different than the DDSDomainParticipantFactory default library (see DDSDomainParticipantFactory::get_default_library).

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