Member Data Documentation

final DestinationOrderQosPolicyKind BY_RECEPTION_TIMESTAMP_DESTINATIONORDER_QOS [static]

[default] Indicates that data is ordered based on the reception time at each com.rti.dds.subscription.Subscriber.

Since each subscriber may receive the data at different times there is no guaranteed that the changes will be seen in the same order. Consequently, it is possible for each subscriber to end up with a different final value for the data.

final DestinationOrderQosPolicyKind BY_SOURCE_TIMESTAMP_DESTINATIONORDER_QOS [static]

Indicates that data is ordered based on a time-stamp placed at the source (by RTI Connext or by the application).

In any case this guarantees a consistent final value for the data in all subscribers.
