Method Detail

generateUUIDback to summary
public UUID generateUUID(SharedSessionContractImplementor session)

Generate the UUID.

Parameters
session:SharedSessionContractImplementor

The session asking for the generation

Returns:UUID

The generated UUID.

getGeneratedVersionback to summary
public int getGeneratedVersion()

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)

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:int

The supported generation version
