Enumeration Type Documentation

Kinds of reliability.

QoS:
DDS::ReliabilityQosPolicy
Enumerator:
BEST_EFFORT_RELIABILITY_QOS  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 DDS::DataReader and DDS::Topic

RELIABLE_RELIABILITY_QOS  Specifies RTI Data Distribution Service will attempt to deliver all samples in its history. Missed samples may be retried.

In steady-state (no modifications communicated via the DDS::DataWriter) RTI Data Distribution Service guarantees that all samples in the DDS::DataWriter history will eventually be delivered to all the DDS::DataReader objects (subject to timeouts that indicate loss of communication with a particular DDS::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 DDS::DataWriter
