Newbie output to byte array question

[fiziwig]

I've Googled this, and looked around in the tutorials, but I haven't
found a simple example of how to assign an output to a byte array.
Maybe I'm just too much of a newbie to know how to navigate the
documentation, but...

What I need is for this code (which does exactly what I want) to put
the output into a byte array instead of into the file "test.txt". How
do I accomplish that?

Thanks,
--gary

FileWriter writer = null;
try {
writer = new FileWriter("test.txt");
MinimalHTMLWriter htmlWriter = new
MinimalHTMLWriter(writer,
(StyledDocument)textRegion.getDocument());
htmlWriter.write();
}
catch (IOException ex) {
... etc...

Are you sure you really mean a byte array, or will a char array do? (and
then you could encode it I suppose)

I'm new to all this but couldn't you use a CharArrayWriter?

I'm not sure. I just need to be able to treat the HTML created by
"write()" as a String.

I don't see why not. I'll have to do some more digging I guess.

ByteArrayOutputStream bos = new ByteArrayOutputStream ();
OutputStreamWriter writer = new OutputStreamWriter (bos, encoding);

// do your writing as above

byte [] result = bos.toByteArray ();

The key here is that you must know the encoding you want to use to convert
the characters in the String into bytes. Check the API for
OutputStreamWriter to see some alternatives for specifying the encoding and
then find out what encoding you want. If you don't specify it will use the
default one of your platform, which means those byte arrays will only be
interpretable by machines that use the same encoding.

In that case, perhaps StringWriter will do the trick ;-)

Thanks for all the suggestions. I went with this solution, which works
fine:

CharArrayWriter writer = null;
try {
writer = new CharArrayWriter();
MinimalHTMLWriter htmlWriter = new
MinimalHTMLWriter(writer, (StyledDocument)textRegion.getDocument());
htmlWriter.write();
}
catch (IOException ex) {
.... etc.
