Overview

The Frontend class is the factory that is to be used to create the Command, NotificationHandler and CallbackHandler objects.

Example

configuration = { :merchant_id => '123456789', :merchant_key => '12345abcd' }

frontend = Google4R::Checkout::Frontend.new(configuration)

Tax Table Factory

You have to set the tax_table_factory attribute of every Frontend object before you can call #create_checkout_command or #create_notification_handler because the objects created by those methods require tax tables.

The Tax Table Factory must provide the method "effective_tax_tables_at" accept a Time object and provide a method that returns an Array of TaxTable object that describe the effective tax rules at the given point of time.

Effectively, this means you have to implement the Temporal Property pattern as described here: http://www.martinfowler.com/ap2/temporalProperty.html.

Example

class TaxTableFactory
def effective_tax_tables_at(time)
  if time < Time.parse("Wed Apr 09 08:56:03 CDT 2003") then
    table1, table2 = TaxTable.new, TaxTable.new
    # ... set rules
    [ table1, table 2]
  else
    table3, table4 = TaxTable.new, TaxTable.new
    # ... set rules
    [ table3, table 4]
  end
end
end

frontend = Google4R::Checkout::Frontend.new(configuration)
frontend.tax_table_factory = TaxTableFactory.new

checkout_command = frontend.create_checkout_command
# ...
handler = frontend.create_notification_handler
