All Implemented Interfaces:

Comparable<SolrVersion>

public final class SolrVersion
extends Object
implements Comparable<SolrVersion>

Simple Solr version representation backed by a Semantic Versioning library. Provides a constant for current Solr version as well as methods to parse string versions and compare versions to each other.

LATEST

public static final SolrVersion LATEST

This instance represents the current (latest) version of Solr.

Method Detail

valueOf

public static SolrVersion valueOf(String version)

Create a SolrVersion instance from string value. The string must comply to the SemVer spec

forIntegers

public static SolrVersion forIntegers(int major,
                                      int minor,
                                      int patch)

Create a SolrVersion instance from set of integer values. Must comply to the SemVer spec

compareVersions

public static int compareVersions(String v1,
                                  String v2)

Compares two versions v1 and v2. Returns negative if v1 isLessThan v2, positive if v1 isGreaterThan v2 and 0 if equal.

toString

Return version as plain SemVer string, e.g. "9.0.1"

Overrides:

toString in class Object

greaterThan
