Enumeration Type Documentation

enum DDS_DataReaderResourceLimitsInstanceReplacementKind

Kinds of instance replacement.

QoS:

DDS_DataReaderResourceLimitsQosPolicy

Enumerator
DDS_NO_INSTANCE_REPLACEMENT_QOS	No instances will be replaced when a new instance is detected and resources are exhausted.
DDS_REPLACE_OLDEST_INSTANCE_REPLACEMENT_QOS	Replace the oldest instance when out of instance resources. When a new instance is detected and resources are exhausted the oldest instance will be removed even if samples with a not read state exists for the instance. Thus, this is a forceful removal of samples and the instance. The freed instance resources will be re-used for the newly detected instance. If there are outstanding loans for the replaced instance the samples can not be freed until returned. However, when the loan is returned the samples are returned back to the free sample pool. Note that the instance will not be rejected.
