// This is PEIP�s (basic) way of the famous starbucks example from
// Gregor Hohpe http://www.eaipatterns.com/ramblings/18_starbucks.html

// Note since this example works in a single threaded environment it
// processes the orders in a synchronous way - every order is placed,
// prepared and delivered one after the other.
// How to avoid this behavior will be shown in further examples.

$context = PEIP\Context\XMLContext::createFromFile(dirname(__FILE__).'/config/config.xml');
$cafe = $context->getGateway('CafeGateway');

The method PEIP\Context\XMLContext::getGateway() has been deprecated.

// this would be the same done by scripting.
