vJASS - Objects with Condition storing.

09-08-2009, 04:48 PM	#1
Anachron	Hey. Just wondering: How do I store a method in an object? I want to be able to get the return value of a method I give with parameters... But I don't know how to do it?

Zerzax	Function interfaces?

No, I want something like this:

JASS:

struct Test
   func toCall = null   

   static method create takes func fc returns thistype
      local thistype tst = Test.allocate()
      set tst.toCall = fc
      return tst
   endmethod
  
   public method checkCon takes nothing returns nothing
      if .toCall() then
          call BJDebugMsg("CONDITION TRUE!")
      endif
   endmethod

endstruct

public function Condition takes nothing returns boolean
   return true
endfunction

// Call from user
call Test.create(function XX)

Anachron	Can someone please post the new code how it will look like with function interfaces?

JASS:

function interface OnTest takes nothing returns nothing 

struct MaTest
    OnTest T
    static method create takes OnTest T returns thistype
        local thistype M = thistype.allocate()
        set M.T = T
        return M
    endmethod
endstruct

function Lol takes nothing returns nothing

endfunction

call MaTest.create(Lol)

Anachron	Thanks alot! :)

azlier	Technically, this is such a lucky situation you have that you could get away with not using function interfaces. Just use a trigger and evaluate it. Do whatever you want.

09-09-2009, 03:13 PM	#9
Anachron	I don't want to evaluate triggers, I just wanted function interfaces, thanks anyway! :)

Vexorian	...Except using triggers would suck misserably. I think a single interface will look better, but hey it is just a matter of taste. And for the n-th time: It is vJass !

What am I doing wrong?

JASS:

function interface onSpawn takes nothing returns nothing
    function interface onCheck takes nothing returns boolean
    function interface onUnitSpawn takes unit u returns nothing  
    
    struct SharedObjects
        onSpawn spawnCall = null
        onCheck checkCall = null
        
        public method setOnSpawnCall takes onSpawn onS returns nothing
            set .spawnCall = onS
        endmethod
        
        private method runOnSpawnCall takes nothing returns nothing
            if .spawnCall != null then
                call .spawnCall()
            endif
        endmethod
        
        public method setOnSpawnCheck takes onCheck onC returns nothing
            set .checkCall = onC
        endmethod
        
        private method runOnSpawnCheck takes nothing returns nothing
            if .checkCall != null then
                return .checkCall()
            endif
            return true
        endmethod
    endstruct

Error:

JASS:

call .spawnCall()

is not an function.

Earth-Fury	Use .evaluate or .execute with function interfaces. Also, function interfaces are not handles, thus you use 0, not null.

Is this correct?

If it compiles and works, then probably. Of course, that's usually true.

Anachron	Don't know if it compiles, don't have a compiler here. Really thanks mate, you are very helpful.
