 *
 * <p><b>Compatibility note:</b> Throughout this API, multibyte values are always interpreted in
 * <i>little-endian</i> order. That is, hashing the byte array {@code {0x01, 0x02, 0x03, 0x04}} is
 * equivalent to hashing the {@code int} value {@code 0x04030201}. If this isn't what you need,
 * methods such as {@link Integer#reverseBytes} and {@link Ints#toByteArray} will help.
