refactor code to use a new static field

[sebastian-toepfer]

I have a project where I use Json-P massively. Now I have realized that I am using it in a very ineffective way. As described at jakartaee/jsonp-api#154. Now I would like to replace all static method calls of class Json with calls against a static field of type JsonProvider. I like refaster, so I ask is it possible to do it with refaster?

let speak the code
i have:

class MassiveJson {

  JsonValue createJson() {
    return Json.createObjectBuilder().add("test", Json.createValue("test")).build();
  }
}

should be replaced by:

class MassiveJson {

  private static final JsonProvider JSONP = JsonProvider.provider();

  JsonValue createJson() {
    return JSONP.createObjectBuilder().add("test", JSONP.createValue("test")).build();
  }
}

Unfortunately his isn't something refaster is currently able to do, it doesn't have a way to add a new field declaration.

thx for carification. should we add this function? or it is a edge case which you will never support?

I wouldn't say never, but I think it's unlikely for refaster to support this any time soon. Refaster's main use-case is rewriting code inside a single method, and I don't see a clear path to adding support for higher level changes that need to add new declarations.
