Class ShortSuffixCombFactory

  • public final class ShortSuffixCombFactory
extends AbstCombFactory
    Concrete factory for creating Short Suffix COMB GUIDs.

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

    The creation minute is a 2 bytes SUFFIX at the LEAST significant bits.

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

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