Detailed Description

This class contains the statistics about the discovered number of org.omg.dds.pub.DataWriters that are compatible with the org.omg.dds.sub.DataReader to which the Status is attached.

DataWriter and DataReader are compatible if they use the same org.omg.dds.topic.Topic and if the QoS requested by the DataReader is compatible with that offered by the DataWriter. A DataWriter will automatically connect to a matching DataReader, but will disconnect when that DataWriter is deleted, when either changes its QoS into an incompatible value, or when either puts its matching counterpart on its ignore-list using the ignoreSubscription or ignorePublication operations on the DomainParticipant.

getLastPublicationHandle()

abstract InstanceHandle org.omg.dds.core.status.SubscriptionMatchedStatus.getLastPublicationHandle ( )

abstract

Handle to the last org.omg.dds.pub.DataWriter that matched the org.omg.dds.sub.DataReader, causing the status to change.

getTotalCount()

abstract int org.omg.dds.core.status.SubscriptionMatchedStatus.getTotalCount ( )

abstract

Total cumulative count the concerned org.omg.dds.sub.DataReader discovered a "match" with a org.omg.dds.pub.DataWriter.

That is, it found a DataWriter for the same org.omg.dds.topic.Topic with a requested QoS that is compatible with that offered by the DataReader.

getTotalCountChange()

abstract int org.omg.dds.core.status.SubscriptionMatchedStatus.getTotalCountChange ( )

abstract

The change in totalCount since the last time the listener was called or the status was read.

noStatuses()

static Set<Class<? extends Status> > org.omg.dds.core.status.Status.noStatuses ( ServiceEnvironment  env )

staticinherited

Parameters

env	Identifies the Service instance to which the object will belong.
