Class StatusDataPersister

java.lang.Object

org.lsst.ccs.localdb.statusdb.BatchPersister<Object[]>

org.lsst.ccs.localdb.statusdb.StatusDataPersister

All Implemented Interfaces:

Runnable, org.lsst.ccs.framework.HasLifecycle, org.lsst.ccs.messaging.AgentPresenceListener, org.lsst.ccs.messaging.MessageListener, org.lsst.ccs.messaging.StatusMessageListener

public class StatusDataPersister
extends BatchPersister<Object[]>
implements org.lsst.ccs.messaging.StatusMessageListener, org.lsst.ccs.messaging.AgentPresenceListener

StatusDataPersister object. Implements StatusListener and updates the db.

Can be run inside a StatusPersisterSubsystem wrapper.

Deprecated use: inside a Message Driver Bean (tied to JMS implementation) TODO this class could be split, to separate the StatusMessageListener functions and put at the same level the three accumulators (status, stat, metadata).
