struct ReliabilityKind_def

Public Types

enum Type

Values:

enumerator BEST_EFFORT: The Data Distribution Service will only attempt to deliver the data; no arrival-checks are being performed and any lost data is not re-transmitted (non-reliable). Presumably new values for the samples are generated often enough by the application so that it is not necessary to resent or acknowledge any samples.

enumerator RELIABLE: The Data Distribution Service will attempt to deliver all samples in the DataWriters history; arrival-checks are performed and data may get re-transmitted in case of lost data. In the steady-state (no modifications communicated via the DataWriter) the Data Distribution Service guarantees that all samples in the DataWriter history will eventually be delivered to the all DataReader objects. Outside the steady-state the HistoryQosPolicy and ResourceLimitsQosPolicy determine how samples become part of the history and whether samples can be discarded from it. In this case also the max_blocking_time must be set.
