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 |
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 |
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
DataWriter s
to write the same instance of the data and if so, how these modifications
should be arbitrated. |
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 |
TypeConsistencyEnforcement |
