I'm just a noob but what about changing "uint8[] buffer " to
"ArrayList<uint8> buffer" and use buffer.add (c);? (--pkg gee-1.0)
You can still access an arraylist with buffer[i] later for convenience.
Also if you enclose line 26 in in a try/catch that first warning goes away.
try {
if (parent.read (&c, 1, null) == 0){
eof = true;
return false;
}
} catch (Error e) {
error ("%s", e.message);
}
