◆ SampleLostStatusKind

enum DDS::SampleLostStatusKind : UINT32

strong

<<extension>> Kinds of reasons why a sample was lost.

Enumerator
NOT_LOST	The sample was not lost. This constant is an extension to the DDS standard. See also DDS::ResourceLimitsQosPolicy
LOST_BY_WRITER	A DDS::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 DDS::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
LOST_BY_OUT_OF_MEMORY	A sample was lost because there was not enough memory to store the sample. This constant is an extension to the DDS standard. See also DDS::DataReaderResourceLimitsQosPolicy

◆ SampleRejectedStatusKind

enum DDS::SampleRejectedStatusKind : UINT32

strong

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

Function Documentation

◆ equals()

bool DDS::DataReaderQos::equals ( DataReaderQos^ other )

Compares two DDS::DataReaderQos for equality.

Parameters

other <<in>> The other DataReaderQos to be compared with this DataReaderQos.

Returns: true if the two Qos objects are equal or false otherwise.
