Class VersionNumber

java.lang.Object

shaded.hudson.util.VersionNumber

All Implemented Interfaces:

java.lang.Comparable<VersionNumber>

public class VersionNumber
extends java.lang.Object
implements java.lang.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.*" This class is re-implemented in 1.415. The class was originally introduced in 1.139

Since:

1.139

digit

@Deprecated
public int digit(int idx)

Deprecated. see getDigitAt(int)

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.
