Does XMLpull pulls charactors from stream ?

Hi all,

I have few questions about the XMLPull parser (may be
I expected this feature too in XMLPull C++ parser)

1. Does the XMLPull parser pulls charactors from the
stream provided with setInput(..). I mean if there is
no enough input available to generate an event does
the parser request the stream ?.

Note:- 
Xerces parsers (DOM, SAX and SAX2) are pushed (given)
a full stream (eg: char* buffer or file) before it
starts parsing.


    start
(next() called)
      |
      v
Request stream  <-----------------------|
for more chars                          |
      |                                 | 
      v                                 |
Got more chars ? ----No---> Error       |
      |                     No data     |
     Yes                    in stream   |
      |                                 |
      v                                 |
Is there enough                         |
chars to generate ----------No----------|
a content event ?
      |
     Yes
      |
      v
Generate a content
handler event
      |
      |
      v
    return
(wait till next()
is called)

May be the Java streams support this feature
automatically (I am not good at Java). I need a C++
pull parser that works like this.

Any idea ?

Cheers ......
