I think this is more meant to be used with non-native JsTypes. When you have a JsType implemented in Java and some JavaScript gives you JS through the Java object's public JS api. That way you can simply generate a delegate method that wraps the Js Array and provides the Java collection API on top of it. However if you use native JsTypes together with JSON.parse() for convert JSON back to JavaScriptObjects you are only dealing with a naming convention and nothing more. Basically JSON.parse() sees your server generated JSON and will construct JS objects natively. Given that JSON.parse() only understands JS Objects, JsArrays and primitives the native JsType you will cast the result of JSON.parse() into, can also only have these types in order to access the underlying data. So if your server REST implementation serializes a Map as two JSON arrays (one for keys, one for values) then your native JsType also needs two JsArray fields in order to access them. The only thing you can do is define a @JsOverlay method that returns a Map implementation that wraps the two JsArrays and then use that @JsOverlay method in your code to get a Map view. Given that you can only modify native JSON.parse() behavior to a limited extend I don't see any other way how a native JsType could transparently add an adapter around JsArrays in a configurable way (different REST server implementations might serialize maps in different ways) other then using @JsOverlay methods. -- J. -- You received this message because you are subscribed to the Google Groups "GWT Contributors" group.
