Haxe 中的局部常量 - 可能

Question

I know there is this question Constants in Haxe about class properties. My question is: is it possible to define constants inside functions? Like:

function foo(){
   const bar=7;
   bar = 8; // should prevent compilation
}

Maybe anything like var var foo:ReadOnlyInt or something?

Answer 1

You're looking for final .

function foo() {
   final bar = 7;
   bar = 8; // not allowed
}
