<<extension>> Kinds of reasons why a sample was lost.
MONITOR-273 We assign an integer to the names in order to be compatible with the DDSMonitoring types.
Enumerator | |
---|---|
NOT_LOST | The sample was not lost. This constant is an extension to the DDS standard. |
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 (DDS::ResourceLimitsQosPolicy::max_instances) was reached. This constant is an extension to the DDS standard.
|
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 (DDS::DataReaderResourceLimitsQosPolicy::max_remote_writers_per_instance) was reached. This constant is an extension to the DDS standard. |
LOST_BY_INCOMPLETE_COHERENT_SET | A sample is lost because it is part of an incomplete coherent set. An incomplete coherent set is a coherent set for which some of the samples are missing. For example, consider a DDS::DataWriter using KEEP_LAST_HISTORY_QOS with a depth of 1. The DataWriter publishes two samples of the same instance as part of a coherent set 'CS1'; the first sample of 'CS1' is replaced by a new sample before it can be successfully delivered to the DDS::DataReader. In this case, the coherent set containing the two samples is considered incomplete. The new sample, by default, will not be provided to the application, and will be reported as LOST_BY_INCOMPLETE_COHERENT_SET. (You can change this default behavior by setting DDS::PresentationQosPolicy::drop_incomplete_coherent_set to FALSE. If you do, the new sample will be provided to the application, but it will be marked as part of an incomplete coherent set in the DDS::SampleInfo structure.) 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. A large coherent set is a coherent set that cannot fit all at once into the DDS::DataReader queue because resource limits are exceeded. For example, if DDS::ResourceLimitsQosPolicy::max_samples_per_instance on the DataReader is 10 and the coherent set has 15 samples for a given instance, the coherent set is a large coherent set that will be considered incomplete. The resource limits that can lead to large coherent sets are: DDS::ResourceLimitsQosPolicy::max_samples, DDS::ResourceLimitsQosPolicy::max_samples_per_instance, DDS::ResourceLimitsQosPolicy::max_instances, and DDS::DataReaderResourceLimitsQosPolicy::max_samples_per_remote_writer. This constant is an extension to the DDS standard. |
LOST_BY_SAMPLES_PER_REMOTE_WRITER_LIMIT | When using DDS::ReliabilityQosPolicyKind::BEST_EFFORT_RELIABILITY_QOS: a resource limit on the number of samples from a given remote writer that a DDS::DataReader may store (DDS::DataReaderResourceLimitsQosPolicy::max_samples_per_remote_writer) was reached. When using DDS::ReliabilityQosPolicyKind::RELIABLE_RELIABILITY_QOS, reaching DDS::DataReaderResourceLimitsQosPolicy::max_samples_per_remote_writer will trigger a rejection, not a loss, with reason DDS::SampleRejectedStatusKind::REJECTED_BY_SAMPLES_PER_REMOTE_WRITER_LIMIT. This constant is an extension to the DDS standard. |
LOST_BY_VIRTUAL_WRITERS_LIMIT | A resource limit on the number of virtual writers from which a DDS::DataReader may read (DDS::DataReaderResourceLimitsQosPolicy::max_remote_virtual_writers) was reached. This constant is an extension to the DDS standard. |
LOST_BY_REMOTE_WRITERS_PER_SAMPLE_LIMIT | A resource limit on the number of remote writers per sample (DDS::DataReaderResourceLimitsQosPolicy::max_remote_writers_per_sample) was reached. This constant is an extension to the DDS standard. |
LOST_BY_AVAILABILITY_WAITING_TIME | DDS::AvailabilityQosPolicy::max_data_availability_waiting_time expired. This constant is an extension to the DDS standard.
|
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 field is currently not used.) This constant is an extension to the DDS standard. |
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. |
LOST_BY_UNKNOWN_INSTANCE | A received sample was lost because it doesn't contain enough information for the reader to know what instance it is associated with. This constant is an extension to the DDS standard. |
LOST_BY_DESERIALIZATION_FAILURE | A received sample was lost because it could not be deserialized. This constant is an extension to the DDS standard. |
LOST_BY_DECODE_FAILURE | When using DDS::ReliabilityQosPolicyKind::BEST_EFFORT_RELIABILITY_QOS: A received sample was lost because it could not be decoded. When using DDS::ReliabilityQosPolicyKind::RELIABLE_RELIABILITY_QOS, the sample will be rejected, not lost, with reason DDS::SampleRejectedStatusKind::REJECTED_BY_DECODE_FAILURE. This constant is an extension to the DDS standard. |
LOST_BY_SAMPLES_PER_INSTANCE_LIMIT | When using DDS::ReliabilityQosPolicyKind::BEST_EFFORT_RELIABILITY_QOS: A resource limit on the number of samples per instance (DDS::ResourceLimitsQosPolicy::max_samples_per_instance) was reached. When using DDS::ReliabilityQosPolicyKind::RELIABLE_RELIABILITY_QOS, reaching DDS::ResourceLimitsQosPolicy::max_samples_per_instance will trigger a rejection, not a loss, with reason DDS::SampleRejectedStatusKind::REJECTED_BY_SAMPLES_PER_INSTANCE_LIMIT. This constant is an extension to the DDS standard.

LOST_BY_SAMPLES_LIMIT | When using DDS::ReliabilityQosPolicyKind::BEST_EFFORT_RELIABILITY_QOS: A resource limit on the number of samples (DDS::ResourceLimitsQosPolicy::max_samples) was reached. When using DDS::ReliabilityQosPolicyKind::RELIABLE_RELIABILITY_QOS, reaching DDS::ResourceLimitsQosPolicy::max_samples will trigger a rejection, not a loss, with reason DDS::SampleRejectedStatusKind::REJECTED_BY_SAMPLES_LIMIT. This constant is an extension to the DDS standard.

Kinds of reasons for rejecting a sample.

Enumerator | |
---|---|
NOT_REJECTED | The sample was not rejected. |
REJECTED_BY_INSTANCES_LIMIT | Connext DDS does not reject samples based on instance limits (DDS::ResourceLimitsQosPolicy::max_instances), so this value will never be used. |
REJECTED_BY_SAMPLES_LIMIT | When using DDS::ReliabilityQosPolicyKind::RELIABLE_RELIABILITY_QOS: A resource limit on the number of samples (DDS::ResourceLimitsQosPolicy::max_samples) was reached. When using DDS::ReliabilityQosPolicyKind::BEST_EFFORT_RELIABILITY_QOS, reaching DDS::ResourceLimitsQosPolicy::max_samples will trigger a loss, not a rejection, with reason DDS::SampleLostStatusKind::LOST_BY_SAMPLES_LIMIT.

REJECTED_BY_SAMPLES_PER_INSTANCE_LIMIT | When using DDS::ReliabilityQosPolicyKind::RELIABLE_RELIABILITY_QOS: A resource limit on the number of samples per instance (DDS::ResourceLimitsQosPolicy::max_samples_per_instance) was reached. When using DDS::ReliabilityQosPolicyKind::BEST_EFFORT_RELIABILITY_QOS, reaching DDS::ResourceLimitsQosPolicy::max_samples_per_instance will trigger a loss, not a rejection, with reason DDS::SampleLostStatusKind::LOST_BY_SAMPLES_PER_INSTANCE_LIMIT.
