JSON(object, *args) click to toggle source

If object is string-like, parse the string and return the parsed result as a Ruby data structure. Otherwise, generate a JSON text from the Ruby data structure object and return it.

The opts argument is passed through to generate/parse respectively. See generate and parse for their documentation.

    str = object.to_str
    if str.is_a?(String)
      return JSON.parse(object.to_str, args.first)
    end
  end

  JSON.generate(object, args.first)
