    In computer science, an iterator is an object that allows a programmer to traverse through all the elements of a collection, regardless of its specific implementation. An iterator is sometimes called a cursor, especially within the context of a database.
    \n–     From Wikipedia<\/a> –<\/p><\/blockquote>\n

    In this particular example you don’t need to use .iterator() as the Hash class is iterable, see http:\/\/haxe.org\/ref\/iterators<\/a> > ‘Iterable Objects’.<\/p>\n

    NOTE:<\/strong> Use myHash.iterator() (mind the parenthesis) and not myHash.iterator as I’m used to from coding AS3.<\/p>\n","protected":false},"excerpt":{"rendered":"
