      • encodeBigEndian

        public static final void encodeBigEndian​(int integer,
                                         byte[] buf)
        Encode integer as a series of 4 bytes into buf starting at position 0 within that buffer.
        Parameters:
        integer - The integer to encode.
        buf - The buffer to write to.

      • encodeBigEndian

        public static final void encodeBigEndian​(int integer,
                                         byte[] buf,
                                         int offset)
        Encode integer as a series of 4 bytes into buf starting at position offset.
        Parameters:
        integer - The integer to encode.
        buf - The buffer to write to.
        offset - The offset within buf to start the encoding.

      • decodeBigEndian

        public static final int decodeBigEndian​(byte[] buf)
        Decode a series of 4 bytes from buf, starting at position 0, and interpret them as an integer.
        Parameters:
        buf - The buffer to read from.
        Returns:
        An integer, as read from the buffer.

      • decodeBigEndian

        public static final int decodeBigEndian​(byte[] buf,
                                        int offset)
        Decode a series of 4 bytes from buf, start at offset, and interpret them as an integer.
        Parameters:
        buf - The buffer to read from.
        offset - The offset with buf to start the decoding.
        Returns:
        An integer, as read from the buffer.
