DataSetWriterIds |
UInt16[] |
List of DataSetWriterIds the information is requested for. The field is encoded as Array with number of elements encoded as Int32 value. For DataSetMetaData probes, the Publisher sends one discovery announcement NetworkMessage for each requested DataSetWriterId. For DataSetWriter configuration probes, the DataSetWriters that belong to one WriterGroup are sent together in one DataSetWriter configuration message. If more than one WriterGroup is affected, this results in a DataSetWriter configuration message per WriterGroup. |
The additional fields for WriterGroup related InformationType in a Publisher information probe message are specified in Table 160.

WriterGroupId |
UInt16 |
This option allows a Publisher information probe for a WriterGroup and the contained DataSetWriters if only the WriterGroupId is known from NetworkMessages. For WriterGroup configuration probes, the DataSetWriters that belong to the WriterGroup are sent together in one DataSetWriter configuration message. |

IncludeDataSetWriters |
Boolean |
Flag indicating if the DataSetWriter should be contained in the PubSubConnection configuration announcement message. |
The additional fields for PubSubConnection configuration in a Publisher information probe message are specified in Table 161.

TransportProfileUris |
String [] |
Filter criteria for the PubSubConnections to return in the PubSubConnection configuration announce message. If TransportProfileUris are set, only PubSubConnection with matching TransportProfileUri shall be returned. If the TransportProfileUris is null or empty, all PubSubConnections are returned. |

IncludeWriterGroups |
Boolean |
Flag indicating if the WriterGroups should be contained in the PubSubConnection configuration announcement message. |
|
IncludeDataSetWriters |
Boolean |
Flag indicating if the DataSetWriters should be contained in the PubSubConnection configuration announcement message. This flag is ignored if IncludeWriterGroups is false. Setting this flag increases the size of the PubSubConnection configuration announcement message and it is more likely that max message sizes are exceeded. |
