◆ build_tree()

static repository::build_tree	(		$fileinfo,
			$search,
			$dynamicmode,

◆ can_be_edited_by_user()

repository::can_be_edited_by_user ( )

◆ reference_file_selected()

repository::reference_file_selected	(	$reference,
		$context,
		$component,
		$filearea,
		$itemid )

inherited

reference_file_selected

This function is called when a controlled link file is selected in a file picker and the form is saved. The expected behaviour for repositories supporting controlled links is to

copy the file to the moodle system account
put it in a folder that reflects the context it is being used
make sure the sharing permissions are correct (read-only with the link)
return a new reference string pointing to the newly copied file.

Parameters

string	$reference	this reference is generated by repository\get_file_reference()
context	$context	the target context for this new file.
string	$component	the target component for this new file.
string	$filearea	the target filearea for this new file.
string	$itemid	the target itemid for this new file.

Return values

string updated reference (final one before it's saved to db).

Reimplemented in repository_nextcloud, and repository_onedrive.

◆ reset_caches()

repository::send_file	(		$storedfile,
			$lifetime = null,
			$filter = 0,
			$forcedownload = false,
		array	$options = null )

inherited

Repository method to serve the referenced file.

See also: send_stored_file

Parameters

stored_file	$storedfile	the file that contains the reference
int	$lifetime	Number of seconds before the file should expire from caches (null means $CFG->filelifetime)
int	$filter	0 (default)=no filtering, 1=all files, 2=html files only

◆ send_relative_file()

repository::send_relative_file	(	stored_file	$mainfile,
			$relativepath )

inherited

Used to allow relative file linking within a repository without creating file records for linked files

Repositories that overwrite this must be very careful - see filesystem repository for example.

Parameters

stored_file	$mainfile	The main file we are trying to access relative files for.
string	$relativepath	the relative path to the file we are trying to access.

Reimplemented in repository_filesystem.

Parameters

string	$plugin	repository plugin name
string	$function	function name

Return values

mixed

◆ supported_filetypes()

repository_flickr_public::supported_filetypes ( )

What kind of files will be in this repository?

Return values

array return '*' means this repository support any files, otherwise return mimetypes of files, it can be an array

Reimplemented from repository.

◆ supported_returntypes()

repository_flickr_public::supported_returntypes ( )

◆ supports_relative_file()

repository::supports_relative_file ( )

inherited

helper function to check if the repository supports send_relative_file.

Return values

true|false

Reimplemented in repository_filesystem.

◆ sync_external_file()

static repository::sync_external_file	(		$file,
			$resetsynchistory = false )

staticinherited

Function repository\sync_external_file() is deprecated.

Use repository\sync_reference instead

Deprecated: since Moodle 2.6 MDL-42016 - please do not use this function any more.

See also: repository\sync_reference()

◆ sync_reference()

repository::sync_reference ( stored_file $file )

inherited

Performs synchronisation of an external file if the previous one has expired.

This function must be implemented for external repositories supporting FILE_REFERENCE, it is called for existing aliases when their filesize, contenthash or timemodified are requested. It is not called for internal repositories (see repository::has_moodle_files()), references to internal files are updated immediately when source is modified.

Referenced files may optionally keep their content in Moodle filepool (for thumbnail generation or to be able to serve cached copy). In this case both contenthash and filesize need to be synchronized. Otherwise repositories should use contenthash of empty file and correct filesize in bytes.

Note that this function may be run for EACH file that needs to be synchronised at the moment. If anything is being downloaded or requested from external sources there should be a small timeout. The synchronisation is performed to update the size of the file and/or to update image and re-generated image preview. There is nothing fatal if syncronisation fails but it is fatal if syncronisation takes too long and hangs the script generating a page.

Note: If you wish to call $file->get_filesize(), $file->get_contenthash() or $file->get_timemodified() make sure that recursion does not happen.

Called from stored_file::sync_external_file()

@uses stored_file\set_missingsource() @uses stored_file\set_synchronized()

Parameters

stored_file $file

Return values

bool	false when file does not need synchronisation, true if it was synchronised

Reimplemented in repository_dropbox, repository_equella, repository_filesystem, and repository_nextcloud.

◆ type_config_form()

static repository_flickr_public::type_config_form	(		$mform,
			$classname = 'repository' )

static

Add Plugin settings input to Moodle form.

Parameters

object $mform

Reimplemented from repository.

◆ type_form_validation()

static repository::type_form_validation	(	$mform,
		$data,
		$errors )

staticinherited

Validate Admin Settings Moodle form.

Parameters

moodleform	$mform	Moodle form (passed by reference)
array	$data	array of ("fieldname"=>value) of submitted data
array	$errors	array of ("fieldname"=>errormessage) of errors

Return values

array array of errors

◆ update_draftfile()

static repository::update_draftfile	(	$draftid,
		$filepath,
		$filename,
		$updatedata )

staticinherited

Updates a file in draft filearea.

This function can only update fields filepath, filename, author, license. If anything (except filepath) is updated, timemodified is set to current time. If filename or filepath is updated the file unconnects from it's origin and therefore all references to it will be converted to copies when filearea is saved.

Parameters

int	$draftid
string	$filepath	path to the directory containing the file, or full path in case of directory
string	$filename	name of the file, or '.' in case of directory
array	$updatedata	array of fields to change (only filename, filepath, license and/or author can be updated)

Exceptions

moodle_exception if for any reason file can not be updated (file does not exist, target already exists, etc.)

◆ uses_post_requests()

repository::uses_post_requests ( )

inherited

Helper function to indicate if this repository uses post requests for uploading files.

Deprecated: since Moodle 3.2, 3.1.1, 3.0.5

Return values

bool

◆ wake_from_cache()

static repository::wake_from_cache ( $data )

staticinherited

Restores the repository from cache.

Implements method from cacheable_object interface.

Return values

array

Implements cacheable_object.
