Detailed Description

The definition of the dds::core::safe_enum ReliabilityKind.

Member Enumeration Documentation

The underlying enum type.

Enumerator:
BEST_EFFORT 

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::sub::DataReader and dds::topic::Topic

RELIABLE 

Specifies that RTI Connext will attempt to deliver all samples in its history. Missed samples may be retried.

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