Method Detail

isEmpty

boolean isEmpty()

Returns:

true if no records

writeRollbackData

void writeRollbackData(byte[] data)

logs the given data These data can be replyed to perform rollback. If writeRollforwardData is called once this method can not be called any more

Parameters:

data -

writeRollbackData

void writeRollbackData(byte[][] data)

logs the given data to perform rollback If writeRollforwardData is called once this method can not be called any more

Parameters:

data -

writeRollforwardData

void writeRollforwardData(byte[][] data)

logs the given data to perfrom rollforward If writeRollforwardData is called once this method can not be called any more

Parameters:

data -

writeRollforwardData

void writeRollforwardData(byte[] data)

logs the given data to perfrom rollforward If writeRollforwardData is called once this method can not be called any more

Parameters:

data -

recover

void recover()

tries to recover all persistent information

isCommitting

boolean isCommitting()

Returns:

indicates that current sequence has received a ROLLFORWARD_DATA message no more logrecord are accepted except XA_DONE to complete the sequence ....

replayRecords

void replayRecords(IDataRecordReplay replay)

Parameters:

replay -

createDataRecord

IDataRecord createDataRecord(XALogRecordType logRecordType,
                             byte[][] recordData)

createDataRecord

IDataRecord createDataRecord(XALogRecordType logRecordType,
                             byte[] recordData)

isClosed

boolean isClosed()

true g.t.w. logger ist disqualified, destroyed or reset

Returns:

disqualify

void disqualify()

closes the dataLogger, but keeps all resources, so the dataLogger can be reopened. The logger can't during the current session of the logging system. This method is called, if the logger is meant to be recover and its content has to be saved til the next recovery.

release

void release()

resets the dataLogger and prepares it for reuse. All data can be discarded. The logger isn't closed

destroy

void destroy()

closes the dataRecorder and destroys all resources/content of the logger
