Examples of sun.misc.HexDumpEncoder

sun.misc.HexDumpEncoder
This class encodes a buffer into the classic: "Hexadecimal Dump" format of the past. It is useful for analyzing the contents of binary buffers. The format produced is as follows:
```
 xxxx: 00 11 22 33 44 55 66 77   88 99 aa bb cc dd ee ff ................ 
```
Where xxxx is the offset into the buffer in 16 byte chunks, followed by ascii coded hexadecimal bytes followed by the ASCII representation of the bytes or '.' if they are not valid bytes. @author Chuck McManis
