Enumeration Type Documentation

enum DDS::SampleLostStatusKind

Kinds of reasons why a sample was lost.

Enumerator:

NOT_LOST	The sample was not lost. See also: ResourceLimitsQosPolicy
LOST_BY_WRITER	A DataWriter removed the sample before being received by the DDS::DataReader. This constant is an extension to the DDS standard.
LOST_BY_INSTANCES_LIMIT	A resource limit on the number of instances was reached. This constant is an extension to the DDS standard. See also: ResourceLimitsQosPolicy
LOST_BY_REMOTE_WRITERS_PER_INSTANCE_LIMIT	A resource limit on the number of remote writers for a single instance from which a DDS::DataReader may read was reached. This constant is an extension to the DDS standard. See also: DDS::DataReaderResourceLimitsQosPolicy
LOST_BY_INCOMPLETE_COHERENT_SET	A sample is lost because it is part of an incomplete coherent set. This constant is an extension to the DDS standard.
LOST_BY_LARGE_COHERENT_SET	A sample is lost because it is part of a large coherent set. This constant is an extension to the DDS standard.
LOST_BY_SAMPLES_PER_REMOTE_WRITER_LIMIT	A resource limit on the number of samples from a given remote writer that a DDS::DataReader may store was reached. This constant is an extension to the DDS standard. See also: DDS::DataReaderResourceLimitsQosPolicy
LOST_BY_VIRTUAL_WRITERS_LIMIT	A resource limit on the number of virtual writers from which a DDS::DataReader may read was reached. This constant is an extension to the DDS standard. See also: DDS::DataReaderResourceLimitsQosPolicy
LOST_BY_REMOTE_WRITERS_PER_SAMPLE_LIMIT	A resource limit on the number of remote writers per sample was reached. This constant is an extension to the DDS standard. See also: DDS::DataReaderResourceLimitsQosPolicy
LOST_BY_AVAILABILITY_WAITING_TIME	DDS::AvailabilityQosPolicy::max_data_availability_waiting_time expired. This constant is an extension to the DDS standard. See also: DDS::DataReaderResourceLimitsQosPolicy
LOST_BY_REMOTE_WRITER_SAMPLES_PER_VIRTUAL_QUEUE_LIMIT	A resource limit on the number of samples published by a remote writer on behalf of a virtual writer that a DDS::DataReader may store was reached. This constant is an extension to the DDS standard. See also: DDS::DataReaderResourceLimitsQosPolicy

enum DDS::SampleRejectedStatusKind

Kinds of reasons for rejecting a sample.

Enumerator:

NOT_REJECTED	Samples are never rejected. See also: DDS::DataReaderResourceLimitsQosPolicy
REJECTED_BY_INSTANCES_LIMIT	A resource limit on the number of instances was reached. See also: DDS::DataReaderResourceLimitsQosPolicy
REJECTED_BY_SAMPLES_LIMIT	A resource limit on the number of samples was reached. See also: DDS::DataReaderResourceLimitsQosPolicy
REJECTED_BY_SAMPLES_PER_INSTANCE_LIMIT	A resource limit on the number of samples per instance was reached. See also: ResourceLimitsQosPolicy
REJECTED_BY_REMOTE_WRITERS_LIMIT	A resource limit on the number of remote writers from which a DDS::DataReader may read was reached. This constant is an extension to the DDS standard. See also: DDS::DataReaderResourceLimitsQosPolicy
REJECTED_BY_REMOTE_WRITERS_PER_INSTANCE_LIMIT	A resource limit on the number of remote writers for a single instance from which a DDS::DataReader may read was reached. This constant is an extension to the DDS standard. See also: DDS::DataReaderResourceLimitsQosPolicy
REJECTED_BY_SAMPLES_PER_REMOTE_WRITER_LIMIT	A resource limit on the number of samples from a given remote writer that a DDS::DataReader may store was reached. This constant is an extension to the DDS standard. See also: DDS::DataReaderResourceLimitsQosPolicy
REJECTED_BY_VIRTUAL_WRITERS_LIMIT	A resource limit on the number of virtual writers from which a DDS::DataReader may read was reached. This constant is an extension to the DDS standard. See also: DDS::DataReaderResourceLimitsQosPolicy
REJECTED_BY_REMOTE_WRITERS_PER_SAMPLE_LIMIT	A resource limit on the number of remote writers per sample was reached. This constant is an extension to the DDS standard. See also: DDS::DataReaderResourceLimitsQosPolicy
REJECTED_BY_REMOTE_WRITER_SAMPLES_PER_VIRTUAL_QUEUE_LIMIT	A resource limit on the number of samples published by a remote writer on behalf of a virtual writer that a DDS::DataReader may store was reached. This constant is an extension to the DDS standard. See also: DDS::DataReaderResourceLimitsQosPolicy
