get_object_vars

  • There are no public object properties of objects in Ruby. Ruby instead uses public methods as properties. Listing the methods for an object in Ruby is discussed in get_class_methods.

    In Ruby we can use the Module#attr_reader method as a way of easily creating accessor methods for instance variables within a class. This is vaguely similar to having a public property.

    PHP

    class Car {
  public  $doors;
  private $isStarted;
}
$vars = get_object_vars(new Car);
var_export($vars);
// => array('doors' => NULL)

    Ruby

    class Car
  attr_reader :doors
 
  private
  def started?
    @started
  end
end
