org.omg.dds.core.policy.QosPolicy

Packages that use QosPolicy

Package	Description
org.omg.dds.core	The Core (Infrastructure) Module defines the abstract classes and the interfaces that are refined by the other modules.
org.omg.dds.core.policy
org.omg.dds.core.status	Statuses may be classified as: Read communication statuses: i.e., those that are related to arrival of data, namely DataOnReadersEvent and DataAvailableEvent.

Uses of QosPolicy in org.omg.dds.core.policy

Subinterfaces of QosPolicy in org.omg.dds.core.policy

Modifier and Type	Interface and Description
interface	DataRepresentation
interface	Deadline DataReader expects a new sample updating the value of each instance at least once every deadline period.
interface	DestinationOrder Controls the criteria used to determine the logical order among changes made by Publisher entities to the same instance of data (i.e., matching Topic and key).
interface	Durability This policy expresses if the data should "outlive" their writing time.
interface	DurabilityService Specifies the configuration of the durability service.
interface	EntityFactory Controls the behavior of the Entity when acting as a factory for other entities.
interface	GroupData User data not known by the middleware, but distributed by means of built-in topics.
interface	History Specifies the behavior of the Service in the case where the value of a sample changes (one or more times) before it can be successfully communicated to one or more existing subscribers.
interface	LatencyBudget Specifies the maximum acceptable delay from the time the data is written until the data is inserted in the receiver's application cache and the receiving application is notified of the fact.
interface	Lifespan Specifies the maximum duration of validity of the data written by the DataWriter.
interface	Liveliness Determines the mechanism and parameters used by the application to determine whether an Entity is "active" (alive).
interface	Ownership [optional] Specifies whether it is allowed for multiple DataWriters to write the same instance of the data and if so, how these modifications should be arbitrated.
interface	OwnershipStrength [optional] Specifies the value of the "strength" used to arbitrate among multiple DataWriter objects that attempt to modify the same instance of a data object (identified by Topic + key).
interface	Partition This policy allows the introduction of a logical partition concept inside the "physical" partition induced by a domain.
interface	Presentation Specifies how the samples representing changes to data instances are presented to the subscribing application.
static interface	QosPolicy.ForDataReader A QosPolicy interface that implements this marker interface applies to DataReader Entities.
static interface	QosPolicy.ForDataWriter A QosPolicy interface that implements this marker interface applies to DataWriter Entities.
static interface	QosPolicy.ForDomainParticipant A QosPolicy interface that implements this marker interface applies to DomainParticipant Entities.
static interface	QosPolicy.ForDomainParticipantFactory A QosPolicy interface that implements this marker interface applies to DomainParticipantFactory objects.
static interface	QosPolicy.ForPublisher A QosPolicy interface that implements this marker interface applies to Publisher Entities.
static interface	QosPolicy.ForSubscriber A QosPolicy interface that implements this marker interface applies to Subscriber Entities.
static interface	QosPolicy.ForTopic A QosPolicy interface that implements this marker interface applies to Topic Entities.
interface	ReaderDataLifecycle Specifies the behavior of the DataReader with regards to the life cycle of the data instances it manages.
interface	Reliability This policy indicates the level of reliability requested by a DataReader or offered by a DataWriter.
interface	ResourceLimits Specifies the resources that the Service can consume in order to meet the requested QoS.
interface	TimeBasedFilter Filter that allows a DataReader to specify that it is interested only in (potentially) a subset of the values of the data.
interface	TopicData User data not known by the middleware, but distributed by means of built-in topics.
interface	TransportPriority This policy is a hint to the infrastructure as to how to set the priority of the underlying transport used to send the data.
interface	TypeConsistencyEnforcement
interface	UserData User data not known by the middleware, but distributed by means of built-in topics.
interface	WriterDataLifecycle Specifies the behavior of the DataWriter with regards to the life cycle of the data instances it manages.
