Title: Calling a function if it exists?
Post by: EK.IceFlake on Sep 17, 2016, 06:47 PM

After so many servers I have made, I got some experience in how to make your code tidy and extensible. I am writing a modular interface which will have to call lots of functions for an event, but only if they exist.

Any idea how to do it?

Thanks

if (my_table/class/instance/whatever.rawin("somefunc"))
my_table/class/instance/whatever.rawget("somefunc").call(this, "sup?");

Worst design decision you could make. Because it involves iterating over a container multiple times to locate something.

Wow... I was experimenting and tried .rawexists instead of .rawin
