var d:Dictionary = new Dictionary(); d["a"] = "b"; d["b"] = "z";
How to get the length/size of the dictionary (which is 2) ?
There is no built-in method to get the size/lenght/count of an AS3 dictionary.
There are workarounds: for example, you can create a custom dictionary class which extends or wraps the flash.utils.Dictionary
class, adding the counter functionality. You can manage the count as entries are added/removed, or count on-demand using a simple For loop iteration:
public static function countKeys(myDictionary:flash.utils.Dictionary):int
{
var n:int = 0;
for (var key:* in myDictionary) {
n++;
}
return n;
}
