thank you.

i see your posting..

and

i write my blog posting

this is great idea!

An Enum is a kind of variable that is not natively available in ActionScript 3.0, but can be found in other languages such as C++. An enum is a type with a restricted set of values.

This uses Scott’s Technique!

Here is a demo;

Then, as you’re transversing through the class structure in CStringUtils.InitEnumConstants, you instantiate the constants there, along with their names.

class EState
{
public var Text :String;
{CStringUtils.InitEnumConstants(EState);} // static ctor

public static const Initializing :EState;
public static const Connecting :EState;
public static const Loading :EState;
public static const Ready :EState;
}

class CStringUtils
{
public static function InitEnumConstants(inType :*) :void
{
var type :XML = flash.utils.describeType(inType);
for each (var constant :XML in type.constant)
{
inType[constant.@name] = new inType();
inType[constant.@name].Text = constant.@name;
}
}

That was about as much automation as I could push it, heh. I really wanted to get rid of the static constructor and find some way to let a base Enum class handle everything, but my current idea would involve calling super(), which would need to have the constructor. Writing out the constructors is a lot more work than writing a one-liner static constructor, so i think sticking with the static is the best thus far.

Nice work, btw. One of the most ingenious ideas I’ve ever seen.
