Parameters

array	$localInfo	Associative array for local repo's info

Find all instances of files with this key.

◆ findBySha1s()

RepoGroup::findBySha1s ( array $hashes )

Find all instances of files with this keys.

Parameters

array $hashes Base 36 SHA-1 hashes

Returns: File[][]

◆ findFile()

RepoGroup::findFile	(	$title,
		$options = `[]`
	)

Otherwise, such files will not be found. latest: If true, load from the latest available data into File objects

Returns: File|bool False if title is not found

◆ findFileFromKey()

RepoGroup::findFileFromKey	(	$hash,
		$options = `[]`
	)

Find an instance of the file with this key, created at the specified time Returns false if the file does not exist.

Parameters

array	$options	Option array, same as findFile()

Returns: File|bool File object or false if it is not found

◆ findFiles()

RepoGroup::findFiles	(	array	$inputItems,

Parameters

array $inputItems An array of titles, or an array of findFile() options with the "title" option giving the title. Example:

$findItem = [ 'title' => $title, 'private' => true ]; $findBatch = [ $findItem ]; $repo->findFiles( $findBatch );

No title should appear in $items twice, as the result use titles as keys

Parameters

int

$flags
