Class UniqueFileStrategy

java.lang.Object

org.apache.log.output.io.rotate.UniqueFileStrategy

All Implemented Interfaces:

FileStrategy

public class UniqueFileStrategy
extends Object
implements FileStrategy

Strategy for naming log files based on appending time suffix. A file name can be based on simply appending the number of miliseconds since (not really sure) 1/1/1970. Other constructors accept a pattern of a SimpleDateFormat to form the appended string to the base file name as well as a suffix which should be appended last. A new UniqueFileStrategy( new File( "foo." ), "yyyy-MM-dd", ".log" ) object will return File objects with file names like foo.2001-12-24.log
