  • Method Details

    • generateNewUUID

      public static UUID generateNewUUID()
      Generate new UUID. Each function call returns a new UUID value.

      UUID version is an implementation detail, and should not be relied on. For now it is UUIDv7, so for increasing instant values, returned UUID is always greater than previous one.

      Returns:
      UUID v7
      Since:
      1.15.0

    • generateNewUUID

      public static UUID generateNewUUID(Instant instant)
      Generate new UUID for an instant of time. Each function call returns a new UUID value.

      UUID version is an implementation detail, and should not be relied on. For now it is UUIDv7, so for increasing instant values, returned UUID is always greater than previous one.

      Based on com.github.f4b6a3.uuid.UuidCreator.getTimeOrderedEpoch implementation (MIT License).

      Parameters:
      instant - a given instant
      Returns:
      UUID v7
      Since:
      1.15.0

    • generateStaticUUID

      public static UUID generateStaticUUID(Instant instant, byte[] data)
      Generate UUID for instant of time and input data. Calling function with same arguments always produces the same result.

      UUID version is an implementation detail, and should not be relied on. For now it is UUIDv7, so for increasing instant values, returned UUID is always greater than previous one. The only difference from RFC 9562 is that least significant bytes are not random, but instead a SHA-1 hash of input data.

      Based on com.github.f4b6a3.uuid.UuidCreator.getTimeOrderedEpoch implementation (MIT License).

      Parameters:
      instant - a given instant
      data - a given data
      Returns:
      UUID v7
      Since:
      1.32.0
