Class Version

java.lang.Object

org.pepsoft.util.Version

All Implemented Interfaces:

Serializable, Comparable<Version>

public final class Version
extends Object
implements Comparable<Version>, Serializable

A version number in decimal dotted notation, with an optional alphanumerical extension separated by a dash.

When comparing the extension is only considered if the versions being compared are numerically equal, where a version with an extension is considered smaller than a version without an extension, and if both versions have an extension they are compared alphanumerically.
