JsonWriter.value( JsonElement ) ?

[Reuben]

Hello!

Any interest by the maintainers to add something like:

       public JsonWriter value( JsonElement value ) ...

to the JsonWriter ?

I'm working with some code where I have TypeAdapters for various classes

that I want to plug into a JsonStream ...

I'd be happy to throw together a patch if it would be considered.

What do you think ?

Cheers,

Reuben

Although I agree that your suggestion would be convenient, in the
meantime you can use:

com.google.gson.internal.Streams.write(JsonElement value, JsonWriter out)

Thanks for the tip! :)

Doh!

Actually - it looks like I would need something like this anyway to access my custom type adapters:

      JsonWriter value( JSonElement v, Type typeOfSrc,  Gson gsonTool )

bla.

Anyway - it looks like I can work around the problem by just calling JsonWriter.flush(),

then dropping down to the underlying java.io.Writer with

       gsonTool.toJson( v, MyClass.class, writer )

scala> val w = new java.io.StringWriter

w: java.io.StringWriter =

scala> val jw = new com.google.gson.stream.JsonWriter( w )

jw: com.google.gson.stream.JsonWriter = com.google.gson.stream.JsonWriter@1e32728a

scala> jw.beginObject.name( "foo" ).value( "fred" ).flush

scala> w.append( """ , "custom":"custom value" """ )

res18: java.io.StringWriter = {"foo":"fred" , "custom":"custom value"

scala> jw.name( "bla" ).value( "boogy" ).endObject.flush

scala> w

res20: java.io.StringWriter = {"foo":"fred" , "custom":"custom value" ,"bla":"boogy"}

Ugh!

Ignore the first part of that last post - I'm thinking of something like this:

     jwriter.name( "foo" ).value( gsonTool.toJsonTree( myObj, MyClass.class ) )

Anyway - I'm on my way - sorry for spamming the group!  ;-)

Cheers,

You might prefer this:

  TypeAdapter<JsonElement> elementAdapter = gson.getTypeAdapter(JsonElement.class);

Then you can use that to do your serialization.

APIs in the 'internal' package are private APIs and can change from release to release.
