      • copy

        public static byte[] copy​(byte[] bytes)

      • toHex

        public static java.lang.String toHex​(byte[] bytes)
        Parameters:
        bytes - Bytes to encode

      • fromHex

        public static byte[] fromHex​(java.lang.String hex)
        Parameters:
        hex - String of hexadecimal digits to decode as bytes.

      • singleFromHex

        public static byte singleFromHex​(java.lang.String hex)
        Parse a single byte from two hexadecimal characters.
        Parameters:
        hex - String of hexadecimal digits to decode as bytes.

      • getUint8

        public static short getUint8​(byte b)
        Read one byte as an unsigned 8-bit integer.

        Result is of type short because Java doesn't have unsigned types.

        Returns:
        A value between 0 and 255, inclusive.

      • getUint16

        public static int getUint16​(byte[] bytes)
        Read 2 bytes as a big endian unsigned 16-bit integer.

        Result is of type int because Java doesn't have unsigned types.

        Returns:
        A value between 0 and 2^16- 1, inclusive.

      • getUint32

        public static long getUint32​(byte[] bytes)
        Read 4 bytes as a big endian unsigned 32-bit integer.

        Result is of type long because Java doesn't have unsigned types.

        Returns:
        A value between 0 and 2^32 - 1, inclusive.

      • readAll

        public static byte[] readAll​(java.io.InputStream is)
                      throws java.io.IOException
        Throws:
        java.io.IOException
