    • encodeInt

      public static void encodeInt​(int value, java.nio.ByteBuffer buffer)
      Encodes a given int value using a variable-length encoding. Each encoded byte starts with an indicator bit, followed by 7 data bits. The data bits are stored in lsb-first fashion to facilitate the encoding, which is more time-critical.
      Parameters:
      value - The value to encode
      buffer - The buffer to write the data to

    • decodeInt

      public static int decodeInt​(java.nio.ByteBuffer buffer)
      Decodes a variable-length integer value stored at the current position in the byte buffer.
      Parameters:
      buffer - The buffer to decode the data from
      Returns:
      The decoded integer value
