An event handler might be a function, a method or even just an object.

// [Function, no data]
	$config['Hooks']['EventName'][] = 'someFunction';	
// result: 
	someFunction($param1, $param2);


// [Function with data]
	$config['Hooks']['EventName'][] = array('someFunction', $someData);	
// result:
	someFunction($someData, $param1, $param2);

	
// [Object only]	
	$config['Hooks']['EventName'][] = $object;
// result:
	$object->onEventName($param1, $param2);

	
// [Object with method]
	$config['Hooks']['EventName'][] = array($object, 'someMethod');	
// result:
	$object->someMethod($param1, $param2);

	
// [Object with method and data]
	$config['Hooks']['EventName'][] = array($object, 'someMethod', $someData);
// result:
	$object->someMethod($someData, $param1, $param2);
