Detailed Description

A org.omg.dds.core.policy.QosPolicy value was incompatible with what was requested.

This class contains the statistics about whether an offered QosPolicy setting was incompatible with the requested QosPolicy setting. The Request/Offering mechanism is applicable between:

• The DataWriter and the DataReader. If the QosPolicy settings between DataWriter and DataReader are incompatible, no communication between them is established. In addition the DataWriter will be informed via a REQUESTED_INCOMPATIBLE_QOS status change and the DataReader will be informed via an OFFERED_INCOMPATIBLE_QOS status change.
• The DataWriter and the Durability Service (as a built-in DataReader). If the QosPolicy settings between DataWriter and the Durability Service are inconsistent, no communication between them is established. In that case data published by the DataWriter will not be maintained by the service and as a consequence will not be available for late joining DataReaders. The QosPolicy of the Durability Service in the role of DataReader is specified by the DurabilityServiceQosPolicy in the Topic.
• The Durability Service (as a built-in DataWriter) and the DataReader. If the QosPolicy settings between the Durability Service and the DataReader are inconsistent, no communication between them is established. In that case the Durability Service will not publish historical data to late joining DataReaders. The QosPolicy of the Durability Service in the role of DataWriter is specified by the DurabilityServiceQosPolicy in the Topic.
