Enumeration Type Documentation

Kinds of reasons for rejecting a sample.

Enumerator:

DDS_NOT_REJECTED	Samples are never rejected. See also: DDS_ResourceLimitsQosPolicy
DDS_REJECTED_BY_INSTANCES_LIMIT	A resource limit on the number of instances was reached. See also: DDS_ResourceLimitsQosPolicy
DDS_REJECTED_BY_SAMPLES_LIMIT	A resource limit on the number of samples was reached. See also: DDS_ResourceLimitsQosPolicy
DDS_REJECTED_BY_SAMPLES_PER_INSTANCE_LIMIT	A resource limit on the number of samples per instance was reached. See also: DDS_ResourceLimitsQosPolicy
DDS_REJECTED_BY_REMOTE_WRITERS_LIMIT	A resource limit on the number of remote writers from which a DDSDataReader may read was reached. This constant is an extension to the DDS standard. See also: DDS_DataReaderResourceLimitsQosPolicy
DDS_REJECTED_BY_SAMPLES_PER_REMOTE_WRITER_LIMIT	A resource limit on the number of samples from a given remote writer that a DDSDataReader may store was reached. This constant is an extension to the DDS standard. See also: DDS_DataReaderResourceLimitsQosPolicy

Kinds of reasons a sample was lost.

Enumerator:

DDS_SAMPLE_LOST_NOT_LOST	Samples was not lost, normal removal. See also: DDS_ResourceLimitsQosPolicy
DDS_SAMPLE_LOST_BY_DATAWRITER	Sample was lost was by the DataWriter, it was never received by the DataReader. See also: DDS_ResourceLimitsQosPolicy
DDS_SAMPLE_LOST_BY_MAX_SAMPLES_LIMIT	A sample was received by the DataReader but lost because the max_samples resource was exceeded and not samples could be freed to receive it. See also: DDS_ResourceLimitsQosPolicy
DDS_SAMPLE_LOST_BY_HISTORY_DEPTH_LIMIT	A sample was received by the DataReader but lost because the max depth was reached for the instance and no samples could be removed from the history. For example, if all the samples in the DataReader cache are loaned by the application, they cannot be removed. See also: DDS_ResourceLimitsQosPolicy
DDS_SAMPLE_LOST_BY_META_SAMPLE_LIMIT	A meta sample was received by the DataReader but lost because the meta sample for the instance was loaned by the application and could not be reused. See also: DDS_ResourceLimitsQosPolicy
DDS_SAMPLE_LOST_BY_NOT_READ_ON_CACHE_DELETION	The DataReader has samples in the cache that were not seen by the application and were lost when the DataReader was deleted. See also: DDS_ResourceLimitsQosPolicy
