Class PhynixxXADataRecorder

java.lang.Object

org.csc.phynixx.loggersystem.logrecord.PhynixxXADataRecorder

All Implemented Interfaces:

IDataRecordSequence, IXADataRecorder

public class PhynixxXADataRecorder
extends Object
implements IXADataRecorder

A PhynixxXADataRecorder is meant to log state information of an transactional resource. A LogRecord is an byte-Array qualified by a XALogRecordType qualifier. This qualifier is interpreted by the caller. A messageSequence is a logical sequence of log records. They describes all log records of a transaction. this class is backwards bound to the PhynixxXARecorderRepository. The current class manages LogEntries but not know the persistence logger.
