com.claritysys.util.Hexadecimal

public final class Hexadecimal
extends java.lang.Object

Provides methods for dumping binary data to a console display.

The class is composed of static methods, and, unfortunately, a static buffer. Thus it is not thread-safe.

Method Detail

printHexRange

public static void printHexRange(byte[] buf,
                                 int addressBegin,
                                 int addressEnd)

Dump a range of memory in hex dump format.

Note that addressBegin will appear flush left, instead of being properly aligned to a 16-byte boundary. It would be a good enhancement, I think, to start printing at the correct column position. For example, dumping from address 0x0003 will currently print:

 0003: 00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00 ........ ........
 

whereas it should print:

 0003:          00 00 00 00 00  00 00 00 00 00 00 00 00 ........ ........
 

Parameters:

buf - The byte array to interpret data from.

addressBegin - The starting address in buf to dump data from.

addressEnd - The ending address.

printHexLine

public static void printHexLine(byte[] buf,
                                int address,
                                int count)

Dump one line of memory as hex dump.

This will dump the 16 bytes or less given in the following format:

 aaaa: hh hh hh hh hh hh hh hh  hh hh hh hh hh hh hh hh  ........ ........
 

printHexByte

public static void printHexByte(byte b)

Print a single byte as a hex pair to System-out.

Parameters:

b - The byte to print.

printHexWord

public static void printHexWord(int word)

Print a single word as a hex quad to System-out.

Parameters:

word - The 2-byte value to print.
