Class Version

java.lang.Object
org.europa.together.domain.Version
All Implemented Interfaces:
Comparable<Version>
public class Version extends Object implements Comparable<Version>
Data class for program version numbers, based on semantic versioning. This implementation allwos to compare and sort version numbers.
Pattern: Major.Minor.Patch-Label (Patch and Label are optional)
true: equals(1.2.3-SNAPSHOT : 1.2.3-SNAPSHOT); true: equals(1.2.3-LABLE : 1.2.3-SNAPSHOT); true: equals(1.0 : 1.0.0); false: equals(1.0 : 1.0.1); false: equals(1.0-LABEL : 1.0); A greater B: compareTo(2.0 : 1.0); A greater B: compareTo(1.1 : 1.0); A greater B: compareTo(1.0.1 : 1.0.0); A greater B: compareTo(2.1 : 1.1); A equal B: compareTo(2.1.1 : 2.1.1-SNAPSHOT); The only recomennded label is SNAPSHOT, because labels are not part of comparing. Definition:
A version of a software artifact is always uniqe. Artifacts can have different versions (1:n relation). That means when an artifact a exist two times and both are not identical, the first artifact has a different version than the second artifact. Both artifacts can not have the same version. If both artifacts with the same name have the same version it is impossible to distinguish them.
