[ActionScript] What does Class() do?

[Xpol Wan]

I'm form Lua with middleclass.lua OO system. 

I don't understand the `Class()` in EntityStateMachine.as line 86 (https://github.com/richardlord/Ash/blob/master/src/ash/fsm/EntityStateMachine.as#L86).

The code:

var newState : EntityState = states[ name ];
//...
if ( currentState )
{
   toAdd = new Dictionary();
   for( t in newState.providers )
   {
     type = Class( t );
     toAdd[ type ] = newState.providers[ type ];
   }
 // ...
}

What does `type = Class( t );` do?

I think EntityState.providers already has class as key.

In lua as a class is a table, I would simpily:

for type, provider in pairs(newState.providers) do
   toAdd[type] = provider
end

Did I missed sth?

Oh, Is `Class(t)` just do a type cast on t?
