Compiles an expression / takes an existing Array/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.


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


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 _readonlyArray = compileFinal [1, 2, 3]; 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.

in Arma 3 v1.70.141838, compileFinal also works for profileNamespace and uiNamespace. But be careful with that.

Change with Arma 3 patch 2.00, compileFinal is now unable to store code type variables in profileNamespace!
