json serializer/deserializer question...

[natami]

Does the json serializer/deserializer support Enums?

eg. Java enums

Yes, it does. You'll need to implement IJsonSerializable in your Enum; and if you want to use ObjectUtils to parse the JSON back into a typed object, add a static fromNative(Object):Object method .

I just fixed a bug with Enum.fromString, so either be sure you have the latest version or parse the enum from the value instead.

Hi, Malachi!

Great - just what i was looking for ;)

What about circular references support?
- In java / hibernate world we often use bi-directional mapping in our models, which I have not found any JsonDeserializer in AS3 able to handle.

Currently the workaround on the server side using Jackson (Json library) is to assign an id to each entity, see post:
http://stackoverflow.com/questions/16478476/jackson-circular-reference

Could something like that be implemented in your serializer?

• I’m currently coding a tool to generate model and service classes from Java to AS3 and supports JSONRPC 2.0 on both java and AS3 side, where your Serializer would come ind very handy.

Regards!

There is unfortunately no support for circular references atm, so you'll probably just get a stack overflow.

I would recommend handling it in your model class since that is outside the scope of the serializer. (ie - I could just set any circular references to null; but the data will be lost since there is no way in JSON to represent a circular data structure.)

If you want to do it that way, just add a [Transient] metadata tag to the properties which hold circular references and they won't be serialized.
