Packages that use org.omg.dds.core.policy

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.
org.omg.dds.domain	The Domain Module contains the DomainParticipant class that acts as an entry-point of the Service and acts as a factory for many of the classes.
org.omg.dds.pub	The Publication Module contains the Publisher and DataWriter interfaces as well as the PublisherListener and DataWriterListener interfaces, and more generally, all that is needed on the publication side.
org.omg.dds.sub	The Subscription Module contains the Subscriber, DataReader, ReadCondition, and QueryCondition interfaces, as well as the SubscriberListener and DataReaderListener interfaces, and more generally, all that is needed on the subscription side.
org.omg.dds.topic	The Topic-Definition Module contains the Topic, ContentFilteredTopic, and MultiTopic interfaces, the TopicListener interface, and more generally, all that is needed by the application to define Topic objects and attach QoS policies to them.

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).

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.
History.Kind
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.
Lifespan Specifies the maximum duration of validity of the data written by the DataWriter.
Liveliness Determines the mechanism and parameters used by the application to determine whether an Entity is "active" (alive).
Liveliness.Kind
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.
Ownership.Kind
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).
Partition This policy allows the introduction of a logical partition concept inside the "physical" partition induced by a domain.
PolicyFactory
Presentation Specifies how the samples representing changes to data instances are presented to the subscribing application.

ReaderDataLifecycle Specifies the behavior of the DataReader with regards to the life cycle of the data instances it manages.
Reliability This policy indicates the level of reliability requested by a DataReader or offered by a DataWriter.
Reliability.Kind
RequestedOffered This interface is implemented by QoS policies that enforce a Request/Offer contract between publications and subscriptions -- that is, for which the level of service offered by the publication is greater than or equal to that requested by the subscription.
ResourceLimits Specifies the resources that the Service can consume in order to meet the requested QoS.
TimeBasedFilter Filter that allows a DataReader to specify that it is interested only in (potentially) a subset of the values of the data.
TopicData User data not known by the middleware, but distributed by means of built-in topics.
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.
TypeConsistencyEnforcement
TypeConsistencyEnforcement.Kind
UserData User data not known by the middleware, but distributed by means of built-in topics.
WriterDataLifecycle Specifies the behavior of the DataWriter with regards to the life cycle of the data instances it manages.
