Class VersionNumber

java.lang.Object

com.sun.istack.test.VersionNumber

All Implemented Interfaces:

java.lang.Comparable<VersionNumber>

public class VersionNumber
extends java.lang.Object
implements java.lang.Comparable<VersionNumber>

Immutable representation of a dot-separated digits (such as "1.0.1"). VersionNumbers are Comparable.

We allow a component to be not just a number, but also "ea", "ea1", "ea2". "ea" is treated as "ea0", and eaN < M for any M > 0.

'*' is also allowed as a component, and '*' > M for any M > 0.

 2.0.* > 2.0.1 > 2.0.0 > 2.0.ea > 2.0
