Neos\Cache\Backend\BackendInterface::remove PHP Метод

Usually this only affects one entry but if - for what reason ever - old entries for the identifier still exist, they are removed as well.

public remove ( string $entryIdentifier ) : boolean
$entryIdentifier	string	Specifies the cache entry to remove
Результат	boolean	TRUE if (at least) an entry could be removed or FALSE if no entry was found

    public function remove($entryIdentifier);
