Interface JdbcActiveMirrorGpsDevice

All Superinterfaces:

ActiveMirrorGpsDevice, CompassGpsDevice, JdbcGpsDevice, MirrorDataChangesGpsDevice

All Known Implementing Classes:

AbstractJdbcActiveMirrorGpsDevice, ResultSetJdbcGpsDevice

public interface JdbcActiveMirrorGpsDevice
extends JdbcGpsDevice, ActiveMirrorGpsDevice

An extension of the JdbcGpsDevice that can also detect real time data changes made to the database and reflect them to the index.

The device will use the JdbcSnapshotEventListener to handle database change events (which should be reflected to the index).

The device will use the provided JdbcSnapshotPersister to persist the snapshot information and load it.
