Enumeration Type Documentation

enum DDS_ReliabilityQosPolicyKind

Kinds of reliability.

QoS:

DDS_ReliabilityQosPolicy

Enumerator:

DDS_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

DDS_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
