splitting the Json to Object into two pass

[GoogleCodeExporter]

To implement a json-rpc protocol, there are three steps.
First parse the json text to find the callee function and parameter types,
Second, based on type discoverd in first step, deseriallize sub-parts of 
json text into different object.
Third, convert result and other logging info into json.

gson only provided to object  to json  api, make it hard to do the first 
and third step.

This request to split the json to object into two pass.
1\ convert json text to json element tree.
2\ convert json element tree to object.

And split the object to json  into two pass.
1\ convert json element tree to object.
2\ convert json text to json element tree.

Is it possibel to add something like 
public JsonElement toJsonElement(Object src, Type typeOfSrc);
and
public JsonElement toJsonElement(string json);

Thanks.

I have a example.

We explored making a change similar to this in 
http://code.google.com/p/google-gson/issues/detail?id=57 

We plan to release Gson 1.4 beta soon and in that we will provide a 
toJsonTree() or some similarly named 
method that will address this issue.

Fixed in r420  by providing toJsonTree methods in Gson.
