Need a method to reconstruct the original schema string before referenced schemas were resolved and inlined by the Parser

public String toString(Collection<Schema> referencedSchemas, boolean pretty) {
  try {
    StringWriter writer = new StringWriter();
    JsonGenerator gen = FACTORY.createGenerator(writer);
    if (pretty) {
      gen.useDefaultPrettyPrinter();
    }
    Schema.Names names = new Schema.Names();
    if (referencedSchemas != null) {
      for (Schema s : referencedSchemas) {
        names.add(s);
      }
    }
    toJson(names, gen);
    gen.flush();
    return writer.toString();
  } catch (IOException e) {
    throw new AvroRuntimeException(e);
  }
}
