Description

Description:
Compiles an expression / takes an existing HashMap and makes it final, preventing it from being modified or overwritten (by = assignation, publicVariable, set or any other command).
ⓘ
This feature is only available in the retail version of Arma 3.
Groups:
Strings

Syntax

Syntax:
compileFinal expression
Parameters:
expression: String, Arma 3 logo black.png2.14 Code or HashMap
Return Value:
Code or HashMap

Examples

Example 1:
_myCode = compileFinal "a = a + 1"; call _myCode; // repeated compile won't have any effect _myCode = compileFinal "a = a + 2";
Example 2:
// duplicate code will be final as well _myDuplicateCode = _myCode; // an alternative is to copy str'd code (since Arma 3 v2.02) private _myNonFinalCopy = compile toString _myCode;
Example 3:
// since Arma 3 v2.14 private _readonlyCode = compileFinal { systemChat "Hello World!"; }; private _readonlyHashMap = compileFinal _myHashMap;

When broadcasting a compileFinal'ed variable using publicVariable or its variants, the variable also becomes final on the other client(s) and/or the server. Also, compileFinal does not prevent event handlers from being removed or overwritten.

Making a base class read only using HashMapObjects
Class_Dog = compileFinal createHashMapObject [ // Properties ["#type", "Dog"], ["owner", objNull], ["legs", 4], ["health", 100], ["vehicleclass", "Dog_Base_F"], ["vehicle", objNull], // Constructor ["#create", { params [["_owner", objNull], ["_vehicle", objNull]]; if ([_owner, _vehicle] findIf {isNull _x} != -1) exitWith {}; _self set ["owner", _owner]; _self set ["vehicle", _vehicle] }] ]; NewDog = createHashMapObject [ [["#base", Class_Dog]], [player_1, createVehicle [Class_Dog get "vehicleclass", [0,0,0], 0, [], "NONE"]] ]; NewDog set ["owner", player_2]; NewDog get "owner"; // returns player_2 Class_Dog set ["owner", player_1]; // Error: Read Only
