public abstract class OMRSAuditLogStoreConnectorBase
extends ConnectorBase
implements OMRSAuditLogStore

OMRSAuditLogStoreConnectorBase is the base class for connectors that support the OMRSAuditLog. It has implementations of the query methods that throw "function not supported". This means that log destinations that do not support queries can ignore these methods. It also supports the start and stop method for the connector which only need to be overridden if the connector has work to do at these times
