Class VersionNumber

java.lang.Object

com.datastax.driver.core.VersionNumber

All Implemented Interfaces:

Comparable<VersionNumber>

public class VersionNumber
extends Object
implements Comparable<VersionNumber>

A version number in the form X.Y.Z with an optional pre-release label (like 1.2.14-SNAPSHOT).

Version numbers compare the usual way, the major number (X) is compared first, then the minor one (Y) and then the patch level one (Z). Lastly, versions with pre-release sorts before the versions that don't have one, and labels are sorted alphabetically if necessary.

Method Detail

parse

public static VersionNumber parse(String version)

Parse a version from a string (of the form X.Y.Z[-label]).

We also parse shorter versions like X.Y[-label] for convenience, but this parse the same as X.Y.0[-label].

Parameters:

version - the string to parse

Throws:

IllegalArgumentException - if the provided string does not represent a valid version

getMajor

public int getMajor()

The major version number.

Returns:

the major version number, i.e. X in X.Y.Z.

getMinor

public int getMinor()

The minor version number.

Returns:

the minor version number, i.e. Y in X.Y.Z.

getPatch

public int getPatch()

The patch version number.

Returns:

the patch version number, i.e. Z in X.Y.Z.

getPreReleaseLabel

public String getPreReleaseLabel()

The pre-release label if relevant, i.e. label in X.Y.Z-label.

Returns:

the pre-release label or null if the version number doesn't have one.
