Detailed Description

Implements some public methods and some protected utility functions which are required by multiple child classes.

Contains stub functionality for unimplemented public methods.

Stub functions which should be overridden are marked with STUB. Some more concrete functions are also typically overridden by child classes.

Note that only the repo object knows what its file class is called. You should never name a file class explictly outside of the repo class. Instead use the repo's factory functions to generate file objects, for example:

RepoGroup::singleton()->getLocalRepo()->newFile( $title );

The convenience functions wfLocalFile() and wfFindFile() should be sufficient in most cases.

Constructor & Destructor Documentation

◆ __construct()

File::__construct	(	$title,
		$repo
	)

Call this constructor from child classes.

Both $title and $repo are optional, though some functions may return false or throw exceptions if they are not set. Most subclasses will want to call assertRepoDefined() here.

Parameters

Title \| string \| bool	$title
FileRepo \| bool	$repo

◆ canAnimateThumbIfAppropriate()

File::canAnimateThumbIfAppropriate ( )

Will the thumbnail be animated if one would expect it to be.

File::createThumb	(	$width,
		$height = `-1`
	)

Create a thumbnail of the image having the specified width/height.

The thumbnail will not be created if the width is larger than the image's width. Let the browser do the scaling in this case. The thumbnail is stored on disk and is only computed if the thumbnail file does not exist OR if it is older than the image. Returns the URL.

Keeps aspect ratio of original image. If both width and height are specified, the generated image will be no bigger than width x height, and will also have correct aspect ratio.

Parameters

◆ $repo

FileRepo LocalRepo ForeignAPIRepo bool File::$repo

Some member variables can be lazy-initialised using __get().

The initialisation function for these variables is always a function named like getVar(), where Var is the variable name with upper-case first letter.

The following variables are initialised in this way in this base class: name, extension, handler, path, canRender, isSafeFile, transformScript, hashPath, pageCount, url

Code within this class should generally use the accessor function directly, since __get() isn't re-entrant and therefore causes bugs that depend on initialisation order. The following member variables are not lazy-initialised
