Enumeration Type Documentation

DataReaderInstanceRemovalKind

enum DDS::DataReaderInstanceRemovalKind : UINT32

strong

Sets the kinds of instances that can be replaced when instance resource limits (DDS::ResourceLimitsQosPolicy::max_instances) are reached.

Enumerator
NO_INSTANCE_REMOVAL	No instance can be removed. If an instance resource is required because DDS::ResourceLimitsQosPolicy::max_instances is reached, this setting will disallow instances from being replaced. Samples for new instances will be dropped and reported as lost with reason DDS::SampleLostStatusKind::LOST_BY_INSTANCES_LIMIT.
EMPTY_INSTANCE_REMOVAL	Only empty instances can be removed. Instances can be replaced only if they are empty. An instance is considered empty when all samples have been taken or removed from the DataReader queue due to the DDS::LifespanQosPolicy or sample purging due to the DDS::ReaderDataLifecycleQosPolicy, and there are no outstanding loans on any of the instance's samples.
FULLY_PROCESSED_INSTANCE_REMOVAL	Only fully-processed instances can be removed. An instance is considered fully processed if every sample for the instance has been processed by the application. A sample is considered processed by the application depending on the DDS::ReliabilityQosPolicy::kind: DDS::ReliabilityQosPolicyKind::RELIABLE_RELIABILITY_QOS (depends on the DDS::ReliabilityQosPolicyAcknowledgmentModeKind): DDS::ReliabilityQosPolicyAcknowledgmentModeKind::PROTOCOL_ACKNOWLEDGEMENT_MODE or DDS::ReliabilityQosPolicyAcknowledgmentModeKind::APPLICATION_AUTO_ACKNOWLEDGEMENT_MODE: The sample is considered processed when it has been read or taken by the application and return_loan has been called. DDS::ReliabilityQosPolicyAcknowledgmentModeKind::APPLICATION_EXPLICIT_ACKNOWLEDGEMENT_MODE: The sample is considered processed when the subscribing application has explicitly acknowledged the DDS sample, the AppAckConf has been received, and the application has called return_loan. DDS::ReliabilityQosPolicyKind::BEST_EFFORT_RELIABILITY_QOS: All samples are considered processed when they have been read or taken by the application and return_loan has been called.
ANY_INSTANCE_REMOVAL	Any instance can be removed. Instances can be replaced regardless of whether the subscribing application has processed all of the samples. Samples that have not been processed will be removed.
