Typedef Documentation

DDS_SampleFlagBits

typedef enum DDS_SampleFlagBits DDS_SampleFlagBits

Type to identify the sample flags reserved by RTI.

DDS_SampleFlag

typedef DDS_Long DDS_SampleFlag

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

DDS_SampleFlagBits

enum DDS_SampleFlagBits

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.
DDS_WRITER_REMOVED_BATCH_SAMPLE	This flag will be set if the sample was accepted into the DataReader queue even though it was marked by the DataWriter as removed. A sample can be marked as removed by the DataWriter in a batch when it is replaced due to the DDS_KEEP_LAST_HISTORY_QOS DDS_HistoryQosPolicy QoS or because the duration in DDS_LifespanQosPolicy was reached. If the DataReader sets the property "dds.data_reader.accept_writer_removed_batch_samples" to true, the removed sample will be accepted into the DataReader queue and this flag will be set.
DDS_DISCOVERY_SERVICE_SAMPLE	This flag will be set if the sample was sent by Cloud Discovery Service. The samples sent by Cloud Discovery Service are participant announcement samples on the ParticipantBuiltinTopic.
