Vargs of different types

[dapper rivet]

Right now the interface looks like this:

        var meta = new BDict(
                new BString("announce"), new BString(announce),
                new BString("created by"), new BString(createdBy),
                new BString("comment"), new BString(comment),
                new BString("encoding"), new BString(encoding),
                new BString("info"), new BDict(
                        new BString("length"), new BInt(length)));

    public BDict(BValue<?>... kv) {

Is there any way I can take either String or Int in vargs and then dispatch correct constructor (either BInt or BString) so this looks something like:

new BDict("announce", announce, "length", 2137)

I looked at stdlib but they do this strange way

Not really, but you can do

new BDict("announce", BValue.of(announce), "length", BValue.of(length));

or

BDict.builder()
  .put("announce", announce)
  .put("length", length)
  .build()

i encountered a very similar problem with my json library

import dev.mccue.json.Json;
import dev.mccue.json.JsonObject;

public class Main {
   public static void main(String[] args) {
      JsonObject swedishChef = Json.objectBuilder()
              .put("name", "chef")
              .put("nationality", "swedish")
              .put("lines", 1)
              .build();

      System.out.println(swedishChef);
   }
}

where if you don't go through the builder you need

        JsonObject.of(Map.of(
                "announce", Json.of("..."),
                "length", Json.of(123)
        ));

now seperately

having BString.of instead of new BString can help you in the future with binary compatibility

also here is that json library: this file has a lot of the conversions, but you can dig through to see more
