  • Method Summary

    Modifier and Type
    Method
    Description
    UUID
    generateUUID(SharedSessionContractImplementor session)
    Deprecated.
    Generate the UUID.
    int
    getGeneratedVersion()
    Deprecated.
    Which variant, according to IETF RFC 4122, of UUID does this strategy generate? RFC 4122 defines 5 variants (though it only describes algorithms to generate 4): 1 = time based 2 = DCE based using POSIX UIDs 3 = name based (md5 hash) 4 = random numbers based 5 = name based (sha-1 hash)

      int getGeneratedVersion()
      Deprecated.
      Which variant, according to IETF RFC 4122, of UUID does this strategy generate? RFC 4122 defines 5 variants (though it only describes algorithms to generate 4):
      • 1 = time based

      • 3 = name based (md5 hash)
      • 4 = random numbers based
      • 5 = name based (sha-1 hash)

      Returning the values above should be reserved to those generators creating variants compliant with the corresponding RFC definition; others can feel free to return other values as they see fit.

      Informational only, and not used at this time.

      Returns:
      The supported generation version
