Class VersionUtil.VersionComparator

java.lang.Object

org.nuiton.util.VersionUtil.VersionComparator

All Implemented Interfaces:

Comparator<Version>

Enclosing class:

VersionUtil

public static class VersionUtil.VersionComparator
extends Object
implements Comparator<Version>

L'implantation d'un comparateur de versions permettant de controler l'ordre du numero de version, classifier et numero de classifer.

Toute implementation de ce contrat devrait suivre cet algorithme :

1) Si versions égales, on quitte.

2) On teste l'ordre des nombres compareNumbers(Version, Version)

Si différent, alors versions différentes, on quitte

3) On teste l'ordre des classifiers compareClassifier(Version, Version)

Si différent, alors versions différentes, on quitte

4) On teste l'ordre des versions de classifiers compareClassifierNumber(Version, Version).
