  • Method Details

    • generate

      public byte[] generate()
      Generate an identifier using an underlying UUID generator.
      Specified by:
      generate in interface UUIDVersionDelegate
      Returns:
      The generated identifier as a byte array.

    • isValidBinary

      public boolean isValidBinary(byte[] binary)
      Check that the binary representation is valid. The service has already checked that it is non-null and a valid length.
      Specified by:
      isValidBinary in interface UUIDVersionDelegate
      Parameters:
      binary - The binary representation.
      Returns:
      true if the binary representation is valid. Otherwise, false.

    • isValidText

      public boolean isValidText(String text)
      Check that the text representation is valid. The service has already checked that it is non-null and a valid length.
      Specified by:
      isValidText in interface UUIDVersionDelegate
      Parameters:
      text - The binary representation.
      Returns:
      true if the text representation is valid. Otherwise, false.

    • toInstant

      public Instant toInstant(byte[] binary)
      Extract the timestamp from the UUID.
      Specified by:
      toInstant in interface UUIDVersionDelegate
      Parameters:
      binary - The binary representation of the UUID.
      Returns:
      The timestamp as an Instant.

    • fromTicks

      public byte[] fromTicks(long ticks, long suffix)
      Create a UUID as a byte array from a timestamp.
      Specified by:
      fromTicks in interface UUIDVersionDelegate
      Parameters:
      ticks - The timestamp in 100 nanoseconds.
      suffix - The second portion of the UUID.
      Returns:
      The UUID as a byte array.
