Class SimpleVersion

java.lang.Object

org.intelligentsia.keystone.boot.SimpleVersion

All Implemented Interfaces:

Serializable, Comparable<SimpleVersion>

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

SimpleVersion class expose methods to compare and analyze version field of JVM Specification.

A version should formatted like this a.b with :

• a: major
• b: medium (optional)

Versioning

• Breaking backward compatibility: major is incremented (medium and minor are reset)
• New additions without breaking backward compatibility: the medium is incremented
