<?php

	 * Engine
	 * 
	 * @var \Model\Engine
	 */

	 * 
	 * @param \Model\Engine $engine
	 */

	{
		$this->engine = $engine;
	}
}

// Register Engine class and set parameter for constructor
$container = new ContainerBuilder();

// Register Tractor object and define param with Engine class for serEngine method
$container->register('my.tractor', '\\Model\\Tractor')
->addMethodCall('setEngine', array(new Reference('my.engine')));		

// Register param for Engine constructor
$container->register('my.engine', '\\Model\\Engine')
->addArgument(1800);

// IoC container will return object registered as my.tractor
$traktor = $container->get('my.tractor');
