org.apache.hedwig.server.persistence.ScanRequest
Encapsulates a request for reading a single message. The message on the given topic at the given seqId is scanned. A call-back {@link ScanCallback}is provided. When the message is scanned, the {@link ScanCallback#messageScanned(Object,Message)} method is called. Sincethere is only 1 record to be scanned the {@link ScanCallback#operationFinished(Object)} method may not be called sinceits redundant. {@link ScanCallback#scanFailed(Object,org.apache.hedwig.exceptions.PubSubException)}method is called in case of error.
