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

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:
$titleTitle|string|bool
$repoFileRepo|bool

Reimplemented in LocalFile.

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 474 of file File.php.

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

File::createThumb ( width,

Determines if this media file is in a format that is unlikely to contain viruses or malicious content.

It uses the global $wgTrustedMediaFormats list to determine if the file is safe.

This is used to show a warning on the description page of non-safe files. It may also be used to disallow direct [[media:...]] links to such files.

Note that this function will always return true if allowInlineDisplay() or isTrustedFile() is true for this file.

Returns:
bool

Definition at line 632 of file File.php.

Returns true if the file is flagged as trusted.

Files flagged that way can be linked to directly, even if that is not allowed for this type of file normally.

This is a dummy function right now and always returns false. It could be implemented to extract a flag from the database. The trusted flag could be set on upload, if the user has sufficient privileges, to bypass script- and html-filters. It may even be coupled with cryptographics signatures or such.

Returns:
bool

Return true if the file is vectorized.

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
