Class FileChannelDataLoggerFactory

java.lang.Object
  org.csc.phynixx.loggersystem.logger.channellogger.FileChannelDataLoggerFactory

All Implemented Interfaces:

IDataLoggerFactory

public class FileChannelDataLoggerFactory
extends Object
implements IDataLoggerFactory

create DataLogger using Files to store data. A logger is qualified by its name and a subsequent integer qualifier. It is possible to have more than one log file for a given logger. The logfile differ in the qualifier.

  A log file is named according to the follwing pattern
  'loggerSystemName'_'loggerName'_'qualifier'.log

 The different parts of the name make i possible to deduce the following information from the logfile name
 1.) loggerSystem
 2.) loggername
 3.) qualifier pof the logfile for the logger
 

A logical logger name has to unique for all logfile of the current loggerfactory. Diese Factory erzeugt FileChannelDataLogger . Es wird ein logischer Name mitgegeben und es wird im Verzeichnis eine datei mit diesem namen angelegt und auf dieser Datei eine TAEnabledRandomAccessFile instanziert.

The logic Name is unique concerning the loggerssytem
