All Implemented Interfaces:

Comparable<String>, RevisionHandler

public class Version
extends Object
implements Comparable<String>, RevisionHandler

This class contains the version number of the current WEKA release and some methods for comparing another version string. The normal layout of a version string is "MAJOR.MINOR.REVISION", but it can also handle partial version strings, e.g. "3.4".
Should be used e.g. in exports to XML for keeping track, with which version of WEKA the file was produced.

Version:
