Class ShortPrefixCombFactory

  • public final class ShortPrefixCombFactory
extends AbstCombFactory
    Concrete factory for creating Short Prefix COMB GUIDs.

    A Short Prefix COMB GUID is a UUID that combines a creation time with random bits.

    The creation minute is a 2 bytes PREFIX at the MOST significant bits.

    The prefix wraps around every ~45 days (2^16/60/24 = ~45).

    The created UUID is a UUIDv4 for compatibility with RFC 9562.
