function ~DataWriter

virtual ~DataWriter() =default

function connect

virtual void connect() =0

connect Connect the DataWriter to the underlying DDS network.

Reimplemented by: iox::dds::CycloneDataWriter::connect

function write

virtual void write(
    iox::dds::IoxChunkDatagramHeader datagramHeader,
    const uint8_t *const userHeaderBytes,
    const uint8_t *const userPayloadBytes
) =0

write Write the provided header and bytes on the DDS network on the topic: serviceId/instanceId/eventId

Parameters:

• datagramHeader with size information
• userHeaderBytes buffer with the user-header
• userPayloadBytes buffer with the user-payload
