public enum Version
extends Enum<Version>

Use by certain classes to match version compatibility across releases of Lucene.

WARNING: When changing the version parameter that you supply to components in Lucene, do not simply change the version at search-time, but instead also adjust your indexing code to match, and re-index.

WARNING: if you use this setting, and then upgrade to a newer release of Lucene, sizable changes may happen. If backwards compatibility is important then you should instead explicitly specify an actual version.

If you use this constant then you may need to re-index all of your documents when upgrading Lucene, as the way text is indexed may have changed. Additionally, you may need to re-test your entire application to ensure it behaves as expected, as some defaults may have changed and may break functionality in your application.

Method Detail

values

public static Version[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
for (Version c : Version.values())
    System.out.println(c);

Returns:
an array containing the constants of this enum type, in the order they are declared

valueOf

public static Version valueOf(String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:
name - the name of the enum constant to be returned.
Returns:
the enum constant with the specified name
Throws:
IllegalArgumentException - if this enum type has no constant with the specified name
NullPointerException - if the argument is null

onOrAfter

public boolean onOrAfter(Version other)

parseLeniently

public static Version parseLeniently(String version)
