Detailed Description

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

Attributes

QosPolicy	Desciption	Default Value
dds::core::policy::UserData	Additional information (info)	UserData::UserData(empty)
dds::core::policy::EntityFactory	Create enabled (info)	EntityFactory::AutoEnable()
org::opensplice::core::policy::ListenerScheduling	Listener thread scheduling parameters	SCHEDULE_DEFAULT, PRIORITY_RELATIVE, prio 0
org::opensplice::core::policy::WatchdogScheduling	Watchdog thread scheduling parameters	SCHEDULE_DEFAULT, PRIORITY_RELATIVE, prio 0

A DomainParticipant will spawn different threads for different purposes:

• A listener thread is spawned to perform the callbacks to all Listener objects attached to the various Entities contained in the DomainParticipant. The scheduling parameters for this thread can be specified in the listener_scheduling field of the DomainParticipantQos.
• A watchdog thread is spawned to report the the Liveliness of all Entities contained in the DomainParticipant whose LivelinessQosPolicyKind in their LivelinessQosPolicy is set to AUTOMATIC_LIVELINESS_QOS. The scheduling parameters for this thread can be specified in the watchdog_scheduling field of the DomainParticipantQos.

A QosPolicy can be set when the DomainParticipant is created or modified with the set qos operations. Both operations take the DomainParticipantQos 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 DomainParticipant creation time or prior to calling the enable operation on the DomainParticipant.

Member Function Documentation

operator<<()

EntityQos& dds::core::EntityQos::operator<< ( const POLICY &  p )

inherited

Generic function for setting a policy applicable to this QoS object. Available policies depend on the actual instantiation of the template class, which might be DomainParticipantQos, TopicQos, PublisherQos, etc.

Parameters

p	the policy to be set for this QoS instance.

operator>>()

const EntityQos& dds::core::EntityQos::operator>> ( POLICY &  p ) const

inherited

Generic function for obtaining the value of a specific policy belonging to this QoS instance.

Returns

policy

policy() [1/3]

EntityQos& dds::core::EntityQos::policy ( const POLICY &  p )

inherited

Generic function for setting a policy applicable to this QoS object. Available policies depend on the actual instantiation of the template class, which might be DomainParticipantQos, TopicQos, PublisherQos, etc.

Parameters

p	the policy to be set for this QoS instance.

policy() [2/3]

const POLICY& dds::core::EntityQos::policy ( ) const

inherited

Generic function for obtaining the value of a specific policy belonging to this QoS instance.

Returns

policy

policy() [3/3]

POLICY& dds::core::EntityQos::policy ( )

inherited

Generic function for obtaining the value of a specific policy belonging to this QoS instance.

Returns

policy
