Method Detail

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.

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

getTarget

public Address getTarget()

Description copied from interface: TargetAwareTransactionLogRecord

Returns target of changes made by this transaction record.

Specified by:

getTarget in interface TargetAwareTransactionLogRecord

Returns:

target of changes made by this transaction record

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

getFactoryId

public int getFactoryId()

Description copied from interface: IdentifiedDataSerializable

Returns DataSerializableFactory factory ID for this class.

Specified by:

getFactoryId in interface IdentifiedDataSerializable

Returns:

factory ID

getId

public int getId()

Description copied from interface: IdentifiedDataSerializable

Returns type identifier for this class. It should be unique per DataSerializableFactory.

Specified by:

getId in interface IdentifiedDataSerializable

Returns:

type ID
