= ROADMAP =
first oop, then overload
allow non binary states (dispatch internally)
= Description =
This Modul should help to manager many states in an complex environment.
You can define callbacks for all states & combinations at one place and later change only the $progress.
I use a very simple approach in an old project and i want to make a easy implementation for a new project.
The events only get fired if a related flag/counter is changed.
I am absolute unsure if there are problems with such a interface (overloading) or should i better use simple function calls ($progress->activate(PROGRESS_FIND);)?
Also the signes for setting & checks flags are my first thought, perhaps i should stick with the default binary operators (but i am most of the time confused with them).
Also i guess i need some modes:
What if someone registered a event with an exact counter like 10 and later increment this counter by 2 from 9 to 11. Should the event fired or not? (mode => 'singlestep')
What is someone want to disallow setting states again? Like PROGRESS_FIND is off and he set PROGRESS_FIND again to off? (mode => 'strict')
ggf. einen speed-mode, der davon ausgeht, das bereit nur bitfields genutzt werden?
