The underlying enum
type.
SYNCHRONOUS |
Indicates to send data synchronously. If rti::core::policy::DataWriterProtocol::push_on_write is true, data is sent immediately in the context of dds::pub::DataWriter::write(). As data is sent immediately in the context of the user thread, no flow control is applied. [default] for dds::pub::DataWriter |
ASYNCHRONOUS |
Indicates to send data asynchronously. Configures the dds::pub::DataWriter to delegate the task of data transmission to a separate publishing thread. The dds::pub::DataWriter::write() call does not send the data, but instead schedules the data to be sent later by its associated dds::pub::Publisher. Each dds::pub::Publisher uses its dedicated publishing thread (rti::core::policy::AsynchronousPublisher) to send data for all its asynchronous DataWriters. For each asynchronous DataWriter, the associated rti::pub::FlowController determines when the publishing thread is allowed to send the data. dds::pub::DataWriter::wait_for_asynchronous_publishing and dds::pub::Publisher::wait_for_asynchronous_publishing enable you to determine when the data has actually been sent.
