Detailed Description

This object provides the basic mechanism for an application to specify Quality of Service attributes for a Publisher.

Attributes

QosPolicy	Desciption	Default Value
dds::core::policy::Presentation	Data-instance change dependencies (info)	Presentation::InstanceAccessScope(coherent=false, ordered=false)
dds::core::policy::Partition	Active partitions (info)	Partition::Partition(empty)
dds::core::policy::GroupData	Additional information (info)	GroupData::GroupData(empty)
dds::core::policy::EntityFactory	Create enabled (info)	EntityFactory::AutoEnable()

A QosPolicy can be set when the Publisher is created or modified with the set qos 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 set qos operation.

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

policy

policy() [1/3]
