Hi,
I've seen the examples of how to set up a reader_qos for multicast in C++.
Sadly, I couldnt easily translate this to work in java.
is there an example of this anywhere or can anyone share?
I assume it's only 1 or 2 lines of code in the reader_qos to add the address?
Hi lmc_aaron,
You can specify the reader's multicast address either programatically:
// ...// Get Default Reader's QoS and modify it before creating// the actual reader.DataReaderQos reader_qos =newDataReaderQos();subscriber.get_default_datareader_qos(reader_qos);// Configure multicast settings and update the Reader's QoS// accordinglyTransportMulticastSettings_t multicastSettings =newTransportMulticastSettings_t();multicastSettings.receive_address = InetAddress.getByName("239.255.1.2");multicastSettings.receive_port = 3456;reader_qos.multicast.value.add(multicastSettings);reader_qos.multicast.kind =TransportMulticastQosPolicyKind.AUTOMATIC_TRANSPORT_MULTICAST_QOS;// Create DataReader with modified QoSreader = (HelloWorldDataReader) subscriber.create_datareader(topic, reader_qos, listener,StatusKind.STATUS_MASK_ALL);if(reader == null) {System.err.println("create_datareader error\n");return;}// ...<dds><qos_libraryname="MulticastTTLLibrary"><qos_profilename="DefaultProfile"><datareader_qos><multicast><value><element><receive_address>239.255.1.2</receive_address><receive_port>3456</receive_address></element></value><kind>AUTOMATIC_TRANSPORT_MULTICAST_QOS</kind></multicast></datareader_qos></qos_profile></qos_library></dds>Thanks,
