[flexcoders] Mapping Java Generics to an AS3 Vector through BlazeDS remoting?
ISTM the natural match between Java Generics and ActionScript is the Vector since it allows one to declare a type for the collection members. And apparently there are some performance gains to be had when using a Vector instead of an Array: http://help.adobe.com/en_US/as3/mobile/WS4bebcd66a74275c3a0f5f19124318fc87b-7fff.html Does anybody have any tips on getting a Vector of objects out of a BlazeDS remoting call? I know I can convert an ArrayCollection to a Vector manually, but that does not seem like a terrible attractive option to me. Jochem -- Jochem van Dieten http://jochem.vandieten.net/

You won't be able to get generic element type information during runtime so what's the point? The only likely approach I guess is generic serializer/deserializer. And still I'm not sure whether vector element type information is serialized/deserialized with vector or is it just a compile time information unreachable during runtime.

That is why Remoting can't distinguish between receiving a generified collection and a regular collection from the Java backend and has to fall back to casting to an arraycollection. But what if I just happen to know and want to force it? The only likely approach I guess is generic serializer/deserializer. That was my idea too. It helps that I am (for now) only looking at a way to do this from Java to ActionScript, but I am still not sure it is worth the effort. Which is why I am hoping somebody else has already tried this.
