6.4.1.6 Datagram DataSetReader

6.4.1.6.1 Address

The Address parameter contains the network address information for the communication middleware related to the DataSetReader. The different Structure DataTypes used to represent the Address are defined in 6.2.7.5.3.

The parameter shall be null if an address is not set at this level. If the parameter is set, it overwrites the Address on the PubSubConnection.

6.4.1.6.2 QosCategory

Selects the general categorty of QoS the DataSetReader requires. Further details are defined in 6.4.1.1.1.

The parameter shall be null or empty if no QoS related parameters are set.

6.4.1.6.3 DatagramQos

The DatagramQos parameter contains the QoS related parameters for the DataSetReader as array of ReceiveQosDataType Structures. The abstract ReceiveQosDataType is defined in 6.4.1.1.5. The concrete subtypes are used to represent different QoS settings that can be combined in the array.

The array shall not contain multiple instances of a concrete subtype e.g. receive PriorityLabel entry.

The parameter shall be null or empty if no QoS related parameters are set.

6.4.1.6.4 Topic

The Topic parameter with DataType String contains the unique name of the data stream from the Publisher that contains the DataSetMessages of interest for the DataSetReader. The Topic is defined by the Publisher.

6.4.1.6.5 DatagramDataSetReaderTransportDataType structure

This Structure DataType is used to represent the datagram transport mapping parameters for DataSetReaders. It is a subtype of the DataSetReaderTransportDataType defined in 6.2.9.13.2.

The DatagramDataSetReaderTransportDataType is formally defined in Table 137.

Its representation in the AddressSpace is defined in Table 138.
