6.2.8 ReaderGroup parameters

6.2.8.1 General

The ReaderGroup does not add parameters to the shared PubSubGroup parameters.

The ReaderGroup is used to group a list of DataSetReaders. It is not symmetric to a WriterGroup and it is not related to a particular NetworkMessage. The NetworkMessage related filter settings are on the DataSetReaders.

TransportSettings

ReaderGroupTransportDataType

Transport mapping specific ReaderGroup parameters. The abstract base type is defined in 6.2.8.2.2. The concrete subtypes are defined in the subclauses for transport mapping specific parameters.

If no concrete subtype is defined for the transport mapping, the field shall be null.

True

MessageSettings

ReaderGroupMessageDataType

NetworkMessage mapping specific ReaderGroup parameters. The abstract base type is defined in 6.2.8.2.3. The concrete subtypes are defined in the subclauses for message mapping specific parameters.

If no concrete subtype is defined for the message mapping, the field shall be null.

True

DataSetReaders

DataSetReaderDataType[]The DataSetReaders contained in the ReaderGroup. The DataSetReader is defined in 6.2.9.
