Field Documentation

DDS_DestinationOrderQosPolicyKind DDS_DestinationOrderQosPolicy::kind

The kind of destination ordering that applies to subscribed data.

[default] DDS_BY_RECEPTION_TIMESTAMP_DESTINATIONORDER_QOS

struct DDS_Duration_t DDS_DestinationOrderQosPolicy::source_timestamp_tolerance

<<eXtension>> Allowed tolerance between source timestamps of consecutive samples.

When a DDS_DataWriter sets DDS_DestinationOrderQosPolicy to DDS_BY_SOURCE_TIMESTAMP_DESTINATIONORDER_QOS, when writing a sample, its timestamp must not be less than the timestamp of the previously written sample. However, if it is less than the timestamp of the previously written sample but the difference is less than this tolerance, the sample will use the previously written sample's timestamp as its timestamp. Otherwise, if the difference is greater than this tolerance, the write will fail.

DDS_BY_SOURCE_TIMESTAMP_DESTINATIONORDER_QOS is not support on the DDS_DataReader.

[default] 100 milliseconds for DDS_DataWriter

[range] [1 nanosec, 1 year]
