def convert
  unless should_convert?
    return { _existing_object_id: array.object_id }
  end

  dumped_ids << array.object_id

  result = array.map do |item|
    UniversalDumper.convert(item, dumped_ids)
  end

  {
    _old_object_id: array.object_id,
    _object_data: result
  }
end

#deconvert {|result| ... } ⇒ Array

Deconverts passed abstract_object back to the original state

Yields:

  • (result)

Returns:

  • (Array)
