haXe Forum > How to loop(traverse) Dictionary

• mac Jul 31 at 05:13

  In AS3 i can loop(traverse) Dictionary by this way:
  ''for (var i:* in dict){
  trace(i);
  }''

  But in haxe,when i do it in the same way, it will alert "Dictionary has no field iterator".
  How can i solve this problem and traverse the haxe Dictionary .Thanks.

  I'm guessing, because haXe is looking for a data structure that has the iterable interface , and the native flash class does not have the iterator() function.

  You can extend the class, and add the function.

  or you could manually loop though it..
  <code haxe>
  for(var i:int = 0; i > dict.length;i++){
  trace(dict[i]);
  }
  <code/>
  or something like that.

  Or you could try use one of the haXe data structures instead?

  (I may have a few details wrong, I'm pretty new to the haXe scene..)

  why do you do not use the haXe native Hash-Class. I think it also uses the AVM2 Dictionary.

  You should have a look at the TypedDictionary class as it wraps dictionary to provide the iterator, aswell as methods for getting and setting values
