Detailed Description

<<extension>> Flags for samples.

Typedef Documentation

Type to identify the sample flags reserved by RTI.

A set of flags that can be associated with a sample.

  • Least-significant bits [0-7] are reserved by RTI
  • Least-significant bits [8-15] are application specific
  • Least-significant bits [15-31] are invalid and cannot be used

Enumeration Type Documentation

Type to identify the sample flags reserved by RTI.

Enumerator:
DDS_REDELIVERED_SAMPLE 

Indicates that a sample has been redelivered by RTI Queuing Service.

DDS_INTERMEDIATE_REPLY_SEQUENCE_SAMPLE 

Indicates that a response sample is not the last response sample for a given request. This bit is usually set by Connext Repliers sending multiple responses for a request.

DDS_REPLICATE_SAMPLE 

Indicates if a sample must be broadcast by one RTI Queuing Service replica to other replicas.

DDS_LAST_SHARED_READER_QUEUE_SAMPLE 

Indicates that a sample is the last sample in a SharedReaderQueue for a QueueConsumer DataReader.

DDS_INTERMEDIATE_TOPIC_QUERY_SAMPLE 

Indicates that a sample for a TopicQuery will be followed by more samples.

This flag only applies to samples that have been published as a response to a DDS_TopicQuery.

When this bit is not set and DDS_SampleInfo::topic_query_guid is different from DDS_GUID_UNKNOWN, this sample is the last sample for that TopicQuery coming from the DataWriter identified by DDS_SampleInfo::original_publication_virtual_guid.
