Design Pattern: Facade and 1-Click Ordering

1-click.rb

class OneClickCheckout
  attr_reader :checkout_process, :default_address, :default_payment
  
  def initialize(order, default_address, default_payment)
    @checkout_process = CheckoutProcess.new(order)
    @default_address = default_address
    @default_payment = default_payment
  end
  
  def click
    @checkout_process.set_shipping_address(default_address)
    @checkout_process.set_payment_method(default_payment)
    @checkout_process.place_order
  end
end
