20.1.1.3.3. DataSharingQosPolicy
- class fastdds.DataSharingQosPolicy(*args)
Qos Policy to configure the data sharing
Notes: Immutable Qos Policy
- add_domain_id(*args)
- automatic(*args)
Overload 1:
Configures the DataSharing in automatic mode
The default shared memory directory of the OS is used. A default domain ID is automatically computed.
Overload 2:
Configures the DataSharing in automatic mode
The default shared memory directory of the OS is used.
- Parameters:
domain_ids (std::vector< uint16_t,std::allocator< uint16_t > >) – the user configured DataSharing domain IDs (16 bits).
Overload 3:
Configures the DataSharing in automatic mode
A default domain ID is automatically computed.
- Parameters:
directory (string) – The shared memory directory to use.
Overload 4:
Configures the DataSharing in automatic mode
- Parameters:
directory (string) – The shared memory directory to use.
domain_ids (std::vector< uint16_t,std::allocator< uint16_t > >) – the user configured DataSharing domain IDs (16 bits).
- clear()
Clears the QosPolicy object
- data_sharing_listener_thread(*args)
Overload 1:
Getter for DataSharing listener thread ThreadSettings
- Return type:
ThreadSettings- Returns:
rtps::ThreadSettings reference
Overload 2:
Getter for DataSharing listener thread ThreadSettings
- Return type:
ThreadSettings- Returns:
rtps::ThreadSettings reference
Overload 3:
Setter for the DataSharing listener thread ThreadSettings
- Parameters:
value (
ThreadSettings) – New ThreadSettings to be set
- domain_ids()
Gets the set of DataSharing domain IDs.
Each domain ID is 64 bit long. However, user-defined domain IDs are only 16 bit long, while the rest of the 48 bits are used for the automatically generated domain ID (if any).
Automatic domain IDs use the 48 MSB and leave the 16 LSB as zero.
User defined domain IDs use the 16 LSB and leave the 48 MSB as zero.
- Return type:
std::vector< uint64_t,std::allocator< uint64_t > >
- Returns:
the current DataSharing domain IDs
- kind()
- Return type:
int
- Returns:
the current DataSharing configuration mode
- max_domains()
- Return type:
int
- Returns:
the current configured maximum number of domain IDs
- off()
Configures the DataSharing in disabled mode
- on(*args)
Overload 1:
Configures the DataSharing in active mode
A default domain ID is automatically computed.
- Parameters:
directory (string) – The shared memory directory to use. It is mandatory to provide a non-empty name or the creation of endpoints will fail.
Overload 2:

- Parameters:
directory (string) – The shared memory directory to use. It is mandatory to provide a non-empty name or the creation of endpoints will fail.
domain_ids (std::vector< uint16_t,std::allocator< uint16_t > >) – the user configured DataSharing domain IDs (16 bits).
- set_max_domains(size)
- Parameters:
size (int) – the new maximum number of domain IDs
- shm_directory()
- Return type:
string
- Returns:
the current DataSharing shared memory directory
- property thisown
The membership flag
