Not exactly a real hascode though. In Java for example, two distinct yet identical (in composition) objects will result in the same hashcode. In Vegas, the hashes will be different because the number is generated incrementally.
Their map implementation is pretty strange as well and does not lend itself to a large number of entries. Access would be very slow after awhile. Better off to use object instances as maps. Since the example you show shows that you are mapping with String keys, it should be fine. Scott On 6/6/06, Bart Wttewaall <[EMAIL PROTECTED]> wrote:
The open-source Vegas framework at osflash.org makes use of a hashmap. Since every Object extends of CoreObject, a hashcode is added to every object. A nice solution, I think. static private var _initHashCode:Boolean = HashCode.initialize(CoreObject.prototype) ; 2006/6/7, Kevin Aebig <[EMAIL PROTECTED]>: > Well the code that your friend is suggesting is pretty straightforward and > you could port it over to AS2 if you wanted.
