final ReliabilityQosPolicyKind BEST_EFFORT_RELIABILITY_QOS [static] |
Indicates that it is acceptable to not retry propagation of any samples.
Presumably new values for the samples are generated often enough that it is not necessary to re-send or acknowledge any samples.
[default] for com.rti.dds.subscription.DataReader and com.rti.dds.topic.Topic
final ReliabilityQosPolicyKind RELIABLE_RELIABILITY_QOS [static] |
Specifies RTI Connext will attempt to deliver all samples in its history. Missed samples may be retried.
In steady-state (no modifications communicated via the com.rti.dds.publication.DataWriter) RTI Connext guarantees that all samples in the com.rti.dds.publication.DataWriter history will eventually be delivered to all the com.rti.dds.subscription.DataReader objects (subject to timeouts that indicate loss of communication with a particular com.rti.dds.subscription.Subscriber).
Outside steady state the HISTORY and RESOURCE_LIMITS policies will determine how samples become part of the history and whether samples can be discarded from it.
[default] for com.rti.dds.publication.DataWriter
