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.

Definition at line 50 of file File.php.

Constructor & Destructor Documentation

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

Reimplemented in LocalFile.

Definition at line 135 of file File.php.

Member Function Documentation

File::__get ( $ name )

File::_getIsSafeFile ( ) [protected]

Uncached accessor.

Returns:: bool

Definition at line 652 of file File.php.

File::allowInlineDisplay ( )

Alias for canRender()

Returns:: bool

Definition at line 614 of file File.php.

File::assertRepoDefined ( ) [protected]

Assert that $this->repo is set to a valid FileRepo instance.

Exceptions:

MWException

Definition at line 1814 of file File.php.

Referenced by ForeignAPIFile\__construct().

File::assertTitleDefined ( ) [protected]

Assert that $this->title is set to a Title.

Exceptions:

MWException

Definition at line 1824 of file File.php.

File::canAnimateThumbIfAppropriate ( )

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

Currently used to add a warning to the image description page

Returns:: bool false if the main image is both animated and the thumbnail is not. In all other cases must return true. If image is not renderable whatsoever, should return true.

Definition at line 473 of file File.php.

File::canRender ( )

Checks if the output of transform() for this file is likely to be valid.

If this is false, various user elements will display a placeholder instead.

Currently, this checks if the file is an image format that can be converted to a format supported by all browsers (namely GIF, PNG and JPEG), or if it is an SVG image and SVG conversion is enabled.

Returns:: bool

Definition at line 580 of file File.php.

Referenced by ForeignAPIFile\transform().

static File::checkExtensionCompatibility	(	File $	old,
		$	new
	)		`[static]`

Checks if file extensions are compatible.

Parameters:

$old	File Old file
$new	string New name

Returns:: bool|null

Definition at line 214 of file File.php.

Referenced by Title\validateFileMoveOperation().

static File::compare	(	File $	a,
		File $	b
	)		`[static]`

Callback for usort() to do file sorts by name.

Parameters:

$a	File
$b	File

Returns:: Integer: result of name comparison

Definition at line 252 of file File.php.

File::convertMetadataVersion	(	$	metadata,

Definition at line 513 of file File.php.

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:

$width	Integer: maximum width of the generated thumbnail
$height	Integer: maximum height of the image (optional)

Returns:: string

Definition at line 812 of file File.php.

FileRepo 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
