[vJASS] Question about structs

[dardas]

Hi, i was wonder if its possible to do this:

struct strExtension
      string data = ""
      public method operator = takes string data returns nothing
            set .data = data
            //Here lies the problem btw, theres no method operator =
      endmethod
      public method operator == takes strExtension s returns boolean
            return .data == s.data
      endmethod
endstruct

library X initializer onInit
      private function onInit takes nothing returns nothing
            local strExtension s = "Hello"
            if s == "Hello" then
                  //Actions #1
            else
                  //Actions #2
            endif
      endfunction
endlibrary

so basicly, the struct gives you the value in the variable called data, instead of the integer.
is it possible?
Sorry if you dont understand, i'm bad at explaining things..

Thanks in advance..

Nope, only possible with integers like ARGB.

That's possible because structs are implemented as integer. I mean you could do some hacks
with StringHash but you would still need an explicit constructor.
Then better use a regular struct with an regular constructor.

Well.. i could use arrays, [] has an operator, and so does []=,
but it will be too much like table of strings.. donno how well that will go ;p
i guess ill give it a try..

or use operator +, if you don't need it...

or just keep the struct member "data" to be publicly usable...

 

[Bribe]

In vJass, you can only overload variable names and operators [], []= and <.

I may add fully-dynamic operators in Luck but I'm undecided on their readability factor.

I've found that using .get() is better ;p
and then i added a color value, so .get(boolean colored)
Thanks for the tip tho ;p

@bribe
if you will do that, that would be really awesome.. thanks ;p

The first version will not allow operator overloading if I start to run low on time, but they may likely end up being added later on (around the time I get a seperate compiler to turn vJass scripts into Luck scripts).

Why not just use a normal member variable? No need to make everything unreadable to save a few keystrokes.

 

[Bribe]

Yeah, operators are really bad for readability. It's a lot easier to understand "this.set(index, val)" and how it operates as a method than to guise the thing using "this[index] = val"

 

[Adiktuz]

or just simply make them as normal members so the user can manipulate them directly...

Usually (unless you're totally insane, which I guess is a possibility) you use operators in place of functions rather than simple variable assignment/retrieval.
