mmm... Are you implying that ActionScript objects are not hashmaps? I thought they were *all* hashmaps (even Arrays are hashmaps). Every method call that you do involves at least one hash lookup.
B. 2006/5/10, Ron Wheeler <[EMAIL PROTECTED]>:
It appears that a HashMap is a Java class that uses a hash on the "key" to store its keys and values. http://java.sun.com/j2se/1.4.2/docs/api/java/util/HashMap.html This would speed up lookup if you have a large set of keys. If you do not need the speed or do not have a large collection of keys to store, an array object would seem to give the same functionality in ActionScript. This leaves the implementation of the array to Flash and it is likely a simple structure that has to be searched sequentially (by the Flash VM) to get the associated value. It you really need a hashing array that can handle large numbers of key/value pairs, you probably have to write one. This is an old concept and you can likely find a few design ideas and probably some code if you search for it. If you are converting code and want to create a HashMap class that has the same methods as HashMap in Java, you could fake the internal storage technology with a simple Array. it would be faster for a small set of values and would get a bit slower as the number of keys increased. You could start with a dumb HashMap class and then make it a true hashing data store later without having to rewrite your code. HashMap was only added to Java in Java 1.1 and they lived without it before then.
