alma.acs.logging.tools.LogFileSplitter

All Implemented Interfaces:

IOPorgressListener, ACSRemoteErrorListener, ACSRemoteLogListener

public class LogFileSplitter
extends java.lang.Object
implements ACSRemoteLogListener, ACSRemoteErrorListener, IOPorgressListener

An object to split a log file in several other shorter file. The criteria is the number of logs or the time (in minutes) A progressive number is appended to the name of the destination for each created file. If the time is the criteria to split the input file, the the date of the first log is appended to the name of the file too.
