in thread A preliminary stab at Flow-Based Programming
But while I've got matts ear... :-) One of the problems I had when putting the Merger together is that apparently SAX elements cannot tell whom sent the event or where the event is going. Because of how I set it up, the Merger SAX events were recieving events from two different streams at the same time due to how SAXT and the event tree worked. I had to use a somewhat icky hack for this (using
which is similar to code in Carp.) in order to id which dataset I was getting this from. Now, of course, on the way to work I thought of a better solution, possibly using closures, that would be able to connect multiple incoming streams at the same component, but I haven't tried to program this in yet. But in general, is there any other way of getting the sending of a SAX event while in a SAX event?do { package DB; @callarr = caller(3); }; my @args = @DB::args; my $sender = $args[0];

It's not what you know, but knowing how to find it if you don't know that's important
