[lttng-dev] Question about filtering bytecode

I'm considering whether I can write a wrapper for the libbabeltrace ctf 
iterator which provides a filtered "next()" method.

I've started reading the code in the hopes of understanding how to do 
this, and yet, I'd really appreciate a link to some ordered documentation, 
or - any other kind of explanation.

For example, one thing I still don't understand is the exact sequence, and 
where the bytecode is actually executed? What is the meaning and purpose 
of "linking" the filter to an event.
