Version (Nuiton Utils :: Nuiton Utils 2.6.3 API)

java.lang.Object
- org.nuiton.util.Version

All Implemented Interfaces:

Serializable, Comparable<Version>
```
public class Version
extends Object
implements Comparable<Version>, Serializable
```
A class to represent an application version with possible classifier.
Replace previously org.nuiton.util.VersionNumber class.
Simple version number is defined like this :
```
 1.0.0 or 1
 
```
A version can be more complex, with a classifier like this :
```
 1.0.0-alpha-1, 1.0.0-beta-2, 1.0.0-rc-1
 
```
A classifier (alpha, beta, rc, ...) must be follwed by a classifier number.
Note :
- initial value is 0
- the equals order is defined on getVersion() property.
- the class is comparable, using the natural version order :
```
0 < 0.1 < 1 < 1.0 < 1.1-alpha-0 < 1.1-alpha-1 < 1.1-beta-0 <
        1.1-rc-1 < 1.1 
```
- the class is immutable, you should not instanciate directly a Version, but prefer use the factory static methods VersionUtil.valueOf(...) instead.
Since:

1.1.0

    boolean to define if version is a snapshot (if so a -SNAPSHOT is added at the end of the textual representation of the version).
    
    Since:
    
    2.4.3
  - classifierNumberAttached
```
protected boolean classifierNumberAttached
```
    A flag to attach or not the classifier with his number.
    If set to false (the default cas then a - will be used to separe them).
    Even if the Version class is immutable, this state can be change since it is only used to build the string representation of a version.
    Notes that this state is NOT used to test equality of two version, neither for the comparaison.
