Method Details

ubytesToInt

public static int ubytesToInt(byte[] uBytes,
 byte endianess)

This method is used for turning up to 4 unsigned bytes into signed integers.

Parameters:

uBytes - one to four Bytes which are interpreted as an unsigned Integer

endianess - determines the order of the bytes: 0 = bigendian, 1 = little endian

ubytesToLong

public static long ubytesToLong(byte[] uBytes,
 byte endianess)

This method is used for turning up to 8 unsigned bytes into signed integers.

Parameters:

uBytes - one to eight Bytes which are interpreted as an unsigned Integer

endianess - determines the order of the bytes: 0 = bigendian, 1 = little endian

readString

public static String readString(InputStream in)
                         throws IOException

Reads characters from a stream until a '\0' character is reached.

Parameters:

in - BufferedInputStream to be read from ( must have been initialized before! )

Throws:

IOException
