    Modifier and Type Method Description
    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.
    static java.lang.String legacyBase64UUID()
    Legacy implementation of base64UUID(), for pre 6.0 indices.
    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
    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
    static SecureString randomBase64UUIDSecureString()
