[TYPO3-mvc] $query-Object style question

[Stefan Frömken]

Hello MVC-Team,

is there a possibility to get this to work?

return $this->createQuery()
	->matching($query->equals('pid', $type))
	->setLimit($amount)
	->setOrderings(array(
		'datetime' => Tx_Extbase_Persistence_QueryInterface::ORDER_DESCENDING,
	))
	->execute()
	->toArray();

The problem is $query->equals. But how to write it correctly.

Stefan
