Neos\Cache\Backend\ApcBackend::remove PHP Method

remove() public method

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
$entryIdentifier string Specifies the cache entry to remove
return boolean TRUE if (at least) an entry could be removed or FALSE if no entry was found
    public function remove($entryIdentifier)
    {
        $this->removeIdentifierFromAllTags($entryIdentifier);
        return apc_delete($this->identifierPrefix . 'entry_' . $entryIdentifier);
    }
