Method Detail

newPrepareOperation

public Operation newPrepareOperation()

Specified by:

newPrepareOperation in interface TransactionLogRecord

newCommitOperation

public Operation newCommitOperation()

Specified by:

newCommitOperation in interface TransactionLogRecord

newRollbackOperation

public Operation newRollbackOperation()

Specified by:

newRollbackOperation in interface TransactionLogRecord

getKey

public Object getKey()

Description copied from interface: TransactionLogRecord

Gets the transaction-log-key that uniquely identifies the TransactionLogRecord within the TransactionLog. E.g. for a map that would be the map-name and the key. So if a map transactional put is done on some key, and if later on another put on that key is done, by using the same transaction-log-key, the first put is overwritten. If null is returned, this TransactionLogRecord can't be identified and can't be overwritten by a later change.

Specified by:

getKey in interface TransactionLogRecord

Returns:

the transaction-log-key that uniquely identifies this TransactionLogRecord.

addOperation

public void addOperation(CollectionTxnOperation operation)

removeOperation

public int removeOperation(long itemId)

createItemIdArray

protected long[] createItemIdArray()

writeData

public void writeData(ObjectDataOutput out)
               throws IOException

Description copied from interface: DataSerializable

Writes object fields to output stream

Specified by:

writeData in interface DataSerializable

Parameters:

out - output

Throws:

IOException

readData

public void readData(ObjectDataInput in)
              throws IOException

Description copied from interface: DataSerializable

Reads fields from the input stream

Specified by:

readData in interface DataSerializable

Parameters:

in - input

Throws:

IOException
