Enumeration Type Documentation

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

Enumerator:
DDS_NOT_LOST 

The sample was not lost.

This constant is an extension to the DDS standard.

See Also
DDS_ResourceLimitsQosPolicy
DDS_LOST_BY_WRITER 

A DDSDataWriter removed the sample before being received by the DDSDataReader.

This constant is an extension to the DDS standard.

DDS_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
DDS_LOST_BY_REMOTE_WRITERS_PER_INSTANCE_LIMIT 

A resource limit on the number of remote writers for a single instance from which a DDSDataReader may read was reached.

This constant is an extension to the DDS standard.

See Also
DDS_DataReaderResourceLimitsQosPolicy
DDS_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.

DDS_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.

DDS_LOST_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
DDS_LOST_BY_VIRTUAL_WRITERS_LIMIT 

A resource limit on the number of virtual writers from which a DDSDataReader may read was reached.

This constant is an extension to the DDS standard.

See Also
DDS_DataReaderResourceLimitsQosPolicy
DDS_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
DDS_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
DDS_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 DDSDataReader may store was reached.

This constant is an extension to the DDS standard.

See Also
DDS_DataReaderResourceLimitsQosPolicy
DDS_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

Enumerator:
DDS_NOT_REJECTED

A resource limit on the number of samples was reached.

See Also
DDS_DataReaderResourceLimitsQosPolicy
DDS_REJECTED_BY_SAMPLES_PER_INSTANCE_LIMIT 

A resource limit on the number of samples per instance was reached.

See Also
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_REMOTE_WRITERS_PER_INSTANCE_LIMIT 

A resource limit on the number of remote writers for a single instance from which a DDSDataReader may read was reached.

This constant is an extension to the DDS standard.

See Also

This constant is an extension to the DDS standard.

See Also
DDS_DataReaderResourceLimitsQosPolicy
DDS_REJECTED_BY_REMOTE_WRITER_SAMPLES_PER_VIRTUAL_QUEUE_LIMIT

Function Documentation

DDS_Boolean DDS_DataReaderQos_equals ( const struct DDS_DataReaderQos self,
const struct DDS_DataReaderQos other 
)

Compares two DDS_DataReaderQos for equality.

Parameters
self<<in>> This DataReaderQos.
other<<in>> The other DataReaderQos to be compared with this DataReaderQos.
Returns
DDS_BOOLEAN_TRUE if the two Qos objects are equal or DDS_BOOLEAN_FALSE otherwise.
