filterFileList	(		$itemName,
			$itemIdentifier,
			$parentIdentifier,
		array	$additionalInformation,
		\TYPO3\CMS\Core\Resource\Driver\DriverInterface	$driver
	)

Entry method for use as filelist filter.

We have to use -1 as the „don't include“ return value, as call_user_func() will return FALSE if calling the method failed and thus we can't use that as a return value.

Parameters

string	$itemName
string	$itemIdentifier
string	$parentIdentifier
array	$additionalInformation	Additional information about the inspected item
\TYPO3\CMS\Core\Resource\Driver\DriverInterface	$driver

Returns

bool|int -1 if the file should not be included in a listing
