| Subject: Cant get readHeader to work |
|
|
I am able to successfully write a header to the file using the supplied writeHeader function. I know this because opening the file up in a bin/hex editor shows

etc. in the form of [character][frequency][space] repeated. All 256 ascii characters are in the file, and the frequencies next to them are exactly as they are in the input files.
My problem is, when I want to decompress and I call readHeader, it only reads in the info for the first 32 characters (not the full 256), then stops.
Here is the code I wrote to display what readHeader is giving me:
(please excuse bad formatting)
Vector HuffmanCharFreqsVector = new Vector();
HuffmanCharFreqsVector = readHeader((FileBitReader)in);
System.out.println("Here is the header that got read in");
for(int i=0; i< HuffmanCharFreqsVector.size(); i++)
{
System.out.println( ((HuffmanCharFreq)HuffmanCharFreqsVector.elementAt(i)).getCharacter().toString() + ((HuffmanCharFreq)HuffmanCharFreqsVector.elementAt(i)).getFrequency() );
}
and here is the output:
Here is the header that got read in

it stops there, and I don't know why! I really dont want to have to rewrite the header read/write code if possible.
Thanks in advance for anyone who has any suggestions. |
