Detailed Description
<<extension>> Kinds of acknowledgment.
Member Data Documentation
◆ PROTOCOL_ACKNOWLEDGMENT_MODE
|
static |
Samples are acknowledged by RTPS protocol.
Samples are acknowledged according to the Real-Time Publish-Subscribe (RTPS) interoperability protocol.
◆ APPLICATION_AUTO_ACKNOWLEDGMENT_MODE
|
static |
Samples are acknowledged automatically after a subscribing application has accessed them.
A sample received by a com.rti.ndds.example.FooDataReader is acknowledged after the subscribing application accesses it, either through calling com.rti.ndds.example.FooDataReader.take or com.rti.ndds.example.FooDataReader.read on the DDS sample. If the read or take operation loans the samples, the acknowledgment is done after com.rti.ndds.example.FooDataReader.return_loan is called. Otherwise, for read or take operations that make a copy, acknowledgment is done after the read or take operations are executed.
◆ APPLICATION_EXPLICIT_ACKNOWLEDGMENT_MODE
|
static |
Samples are acknowledged after the subscribing application explicitly calls acknowledge on the samples.
Samples received by a com.rti.dds.subscription.DataReader are explicitly acknowledged by the subscribing application, after it calls either com.rti.dds.subscription.DataReader.acknowledge_all or com.rti.dds.subscription.DataReader.acknowledge_sample.
