jreceiver.util.text
Class WordFormatB  

java.lang.Object
  jreceiver.util.text.FormatB
      jreceiver.util.text.WordFormatB

---

public class WordFormatB

extends FormatB

Formatter to output an object in 4 bytes.

Implementation presently assumes 4-byte integers.

Word example:

 String pattern = "{0,word}{1,word,be}{2,word,le}";
 MessageFormatB mfb = new MessageFormatB(pattern);
 Object[] objs = { new Integer(0xAABBCCDD),
                   new Integer(0xAABBCCDD),
                   new Integer(0xAABBCCDD) };
 byte[] = mfb.format(objs);
 

{0,word} encoded as a 4-byte word using the default big-endian (Mac) order (result = AA BB CC DD)

{1,word,be} same as {0}

{2,word,le} encoded as a 4-byte word using the little-endian (Intel) order (result = DD CC BB AA)

There are two byte orders available for formatting words:

 --------------------------- ---------------------------
|            MSB            |           LSB             |
| ------------------------- | ------------------------- |
| Big Endian                | Little Endian             |
| MostSignificantByteFirst  | LeastSignificantByteFirst |
| "Network" Order           | "VAX" order               |
| Java/Sun/Mac/IBM390       | Intel/Windows/AMD/DEC/VAX |
| used by Blefuscudians     | used by Lilliputians      |
| 0xCAFEBABE = CA FE BA BE  | 0xCAFEBABE = BE BA FE CA  |
 --------------------------- ---------------------------
 

MSB is the default of Java and therefore the default of JReceiver.

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

Specified by:

toString in class FormatB
