[tcljava-dev] New IO subsystem for Jacl checked in

[Mo D. <md...@un...>]

Hey all.

It took quite some doing, but I finally managed to get a port of the
Tcl IO subsystem working in Jacl. I just checked it into the CVS.
It supports binary IO as well as encoded IO and all the normal
fconfigure options should be working now. Jacl now does all
its own buffering and character conversion. Jacl should now
do IO exactly the same as Tcl, except that fileevent is not
yet implemented so you can't do async IO.

This implementation is not optimized yet, there are still some
things that could be done to avoid some buffer allocation but
it does pass almost all of the test cases. The only real bummer
is the fact that I had to use the sun.io.CharToByteConverter
and sun.io.ByteToCharConverter classes because there is no
Java API that supports character conversion. There are some
new character conversion classes in JDK 1.4, but adding
that support is still on the TODO list.

cheers
Mo
