If you look at the implementations of any of the BinInputStream
derivatives, you'll see that they simply return 0 from readBytes() to
signal the end-of-stream condition.
By the way, you should be prepared for readBytes() to be called once more
after having returned 0 the first time. At least that's been my
experience.

Hello,
I need to give the input data one buffer at a time to Xerces.
I don't know in advance the length of the input data.
I cannot give it all at once to Xerces either.
I was thinking of deriving a "MyInputStream" from a BinInputStream and
getting the data inside readBytes, but what is the "right" way to signal
the
end of the data ?
By returning 0 from readBytes (which is the length of available data, I
gather) ? or by throwing an exception ?
Thanks
-- Jean-Marc
