TxnReservePollOperation

public TxnReservePollOperation()

TxnReservePollOperation

public TxnReservePollOperation(String name,
                               long timeoutMillis,
                               long reservedOfferId,
                               String transactionId)
Method Detail

run

public void run()
         throws Exception
Specified by:
run in class Operation
Throws:
Exception

getWaitKey

public WaitNotifyKey getWaitKey()
Specified by:
getWaitKey in interface WaitSupport

shouldWait

public boolean shouldWait()
Specified by:
shouldWait in interface WaitSupport

onWaitExpire

public void onWaitExpire()
Specified by:
onWaitExpire in interface WaitSupport

getId

public int getId()
Description copied from interface: IdentifiedDataSerializable
Returns type identifier for this class. Id should be unique per DataSerializableFactory.

Specified by:
getId in interface IdentifiedDataSerializable
Returns:
type id

writeInternal

protected void writeInternal(ObjectDataOutput out)
                      throws IOException
Overrides:
writeInternal in class QueueOperation
Throws:
IOException

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException
Overrides:
readInternal in class QueueOperation
Throws:
IOException

shouldBackup

public boolean shouldBackup()
Description copied from interface: BackupAwareOperation
Checks if a backup needs to be made.
