[vJASS] Help with stub method

[Molekylee]

Hey guys

I have a stub method in a parent struct and I want it to be called ONLY if it is overrriden in a child struct.
What's the best way to do this?

I was hoping something like this would work:

struct parentstruct
    stub method onPeriodic takes nothing returns nothing
    endmethod

    private static method periodic takes nothing returns nothing
        if this.onPeriodic != null then
            call this.onPeriodic()
        endif
    endmethod
endstruct

Thank you

Whats the issue on making the stub method do nothing in the parent and always calling it? Shouldn't matter too much performance-wise.

My concern was indeed the performance of calling multiple do nothing-stub methods. I suppose the performance wouldn't be any better with multiple if statements anyways.
Thanks Anachron

I agree with Anachron, by object orientated design, it shouldn't be a problem if the parent's method is called in case the method isn't overwritten. The struct that is calling the stub method should not care for implementation / make checks for it.
