Detailed Description

This struct provides the basic mechanism for an application to specify Quality of Service attributes for an IPublisher.

A QosPolicy can be set when the IPublisher is created with the IDomainParticipant.CreatePublisher operation (or modified with the SetQos operation). Both operations take the PublisherQos object as a parameter. There may be cases where several policies are in conflict. Consistency checking is performed each time the policies are modified when they are being created and, in case they are already enabled, via the SetQos operation.

Some QosPolicy have “immutable” semantics meaning that they can only be specified either at IPublisher creation time or prior to calling the enable operation on the IPublisher.

The initial value of the default PublisherQos in the IDomainParticipant are given in the following table:

QosPolicy	Attribute	<Default Value
PublisherQos.EntityFactory	EntityFactoryQosPolicy.AutoEnableCreatedEntities	true
PublisherQos.Partition	PartitionQosPolicy.Name	null
PublisherQos.GroupData	GroupDataQosPolicy.Value	empty
PublisherQos.Presentation	PresentationQosPolicy.AccessScope	InstancePresentationQos
	PresentationQosPolicy.CoherentAccess	false
	PresentationQosPolicy.OrderedAccess	false
