base64UUID

public static java.lang.String base64UUID()

Generates a time-based UUID (similar to Flake IDs), which is preferred when generating an ID to be indexed into a Lucene index as primary key. The id is opaque and the implementation is free to change at any time!

legacyBase64UUID

public static java.lang.String legacyBase64UUID()

Legacy implementation of base64UUID(), for pre 6.0 indices.

randomBase64UUID

public static java.lang.String randomBase64UUID(java.util.Random random)

Returns a Base64 encoded version of a Version 4.0 compatible UUID as defined here: http://www.ietf.org/rfc/rfc4122.txt, using the provided Random instance

randomBase64UUID

public static java.lang.String randomBase64UUID()

Returns a Base64 encoded version of a Version 4.0 compatible UUID as defined here: http://www.ietf.org/rfc/rfc4122.txt, using a private SecureRandom instance
