Class VersionNumber

java.lang.Object
org.jenkinsci.remoting.util.VersionNumber
All Implemented Interfaces:
Comparable<VersionNumber>
public class VersionNumber extends Object implements Comparable<VersionNumber>
Immutable representation of a version number based on the Mercury version numbering scheme. VersionNumbers are Comparable.

Special tokens

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.

'SNAPSHOT' is also allowed as a component, and "N.SNAPSHOT" is interpreted as "N-1.*" 

 2.0.* < 2.0.1 < 2.0.1-SNAPSHOT < 2.0.0.99 < 2.0.0 < 2.0.ea < 2.0
This class is re-implemented in 1.415. The class was originally introduced in 1.139

    • getDigitAt

      public int getDigitAt(int idx)
      Returns a digit (numeric component) by its position. Once a non-numeric component is found all remaining components are also considered non-numeric by this method.
      Parameters:
      idx - Digit position we want to retrieve starting by 0.
      Returns:
      The digit or -1 in case the position does not correspond with a digit.
