java.lang.Object

org.apache.ambari.server.utils.MpackVersion

All Implemented Interfaces:

Comparable<MpackVersion>

public class MpackVersion
extends Object
implements Comparable<MpackVersion>

This class should be used to compare mpack and stack versions. Base method which should be used is parse/parseStackVersion, depends on which versions you want to compare. This method will validate and parse version which you will pass as parameter, and return object of current class with parsed version. Same thing you should do with another version, with which you are planning to compare previous one. After that, use method compare to get final result.
