  • Method Details

    • copy

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

    • toHex

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

    • fromHex

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

    • singleFromHex

      public static byte singleFromHex(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.

    • encodeUint16

      public static byte[] encodeUint16(int value)

    • encodeUint32

      public static byte[] encodeUint32(long value)

    • readAll

      public static byte[] readAll(InputStream is) throws IOException
      Throws:
      IOException
