Member Function Documentation

ResourceLoaderModule::getDependencies ( )

Get a list of modules this module depends on.

Dependency information is taken into account when loading a module on the client side. When adding a module on the server side, dependency information is NOT taken into account and YOU are responsible for adding dependent modules as well. If you don't do this, the client side loader will send a second request back to the server to fetch the missing modules, which kind of defeats the purpose of the resource loader.

To add dependencies dynamically on the client side, use a custom loader script, see getLoaderScript()

Returns:: Array: List of module names as strings

Reimplemented in ResourceLoaderFileModule, and ResourceLoaderUserCSSPrefsModule.

Definition at line 272 of file ResourceLoaderModule.php.

ResourceLoaderModule::getFileDependencies ( $ skin )

Get the files this module depends on indirectly for a given skin.

Currently these are only image files referenced by the module's CSS.

Parameters:

$skin String: Skin name

Returns:: Array: List of files

ResourceLoaderModule::getLoaderScript ( )

Get the loader JS for this module, if set.

Returns:: Mixed: JavaScript loader code as a string or boolean false if no custom loader set

Reimplemented in ResourceLoaderFileModule.

Definition at line 252 of file ResourceLoaderModule.php.

ResourceLoaderModule::getMessages ( )

Get the messages needed for this module.

To get a JSON blob with messages, use MessageBlobStore::get()

Returns:: Array: List of message keys. Keys may occur more than once

Reimplemented in ResourceLoaderFileModule.

Definition at line 211 of file ResourceLoaderModule.php.

Referenced by MessageBlobStore\generateMessageBlob(), getMsgBlobMtime(), and MessageBlobStore\insertMessageBlob().

Here is the caller graph for this function:

ResourceLoaderModule::getModifiedTime ( ResourceLoaderContext $ context )

Get this module's last modification timestamp for a given combination of language, skin and debug mode flag.

This is typically the highest of each of the relevant components' modification timestamps. Whenever anything happens that changes the module's contents for these parameters, the mtime should increase.

NOTE: The mtime of the module's messages is NOT automatically included. If you want this to happen, you'll need to call getMsgBlobMtime() yourself and take its result into consideration.

Parameters:

$context ResourceLoaderContext: Context object

Returns:: Integer: UNIX timestamp

Reimplemented in ResourceLoaderFileModule, ResourceLoaderStartUpModule, ResourceLoaderWikiModule, ResourceLoaderUserCSSPrefsModule, and ResourceLoaderUserOptionsModule.

Definition at line 367 of file ResourceLoaderModule.php.

ResourceLoaderModule::getMsgBlobMtime ( $ lang )

Get the last modification timestamp of the message blob for this module in a given language.

Parameters:

$lang String: Language code

Returns:: Integer: UNIX timestamp, or 0 if the module doesn't have messages

Definition at line 320 of file ResourceLoaderModule.php.

Here is the caller graph for this function:

ResourceLoaderModule::getName ( )

Get this module's name.

This is set when the module is registered with ResourceLoader::register()

Returns:: Mixed: Name (string) or null if no name was set

Referenced by getFileDependencies(), getMsgBlobMtime(), getScriptURLsForDebug(), ResourceLoaderFileModule\getStyles(), and getStyleURLsForDebug().

Here is the caller graph for this function:

ResourceLoaderModule::getOrigin ( )

Get this module's origin.

This is set when the module is registered with ResourceLoader::register()

Returns:: Int ResourceLoaderModule class constant, the subclass default if not set manuall

Definition at line 94 of file ResourceLoaderModule.php.

Referenced by OutputPage\filterModules().

Here is the caller graph for this function:

ResourceLoaderModule::getPosition ( )

Where on the HTML page should this module's JS be loaded? 'top': in the <head> 'bottom': at the bottom of the <body>

Returns:: string

Reimplemented in ResourceLoaderFileModule.

Definition at line 243 of file ResourceLoaderModule.php.

ResourceLoaderModule::getScript ( ResourceLoaderContext $ context )

Get all JS for this module for a given language and skin.

Includes all relevant JS except loader scripts.

Parameters:

$context ResourceLoaderContext: Context object

Returns:: String: JavaScript code

Reimplemented in ResourceLoaderFileModule, ResourceLoaderStartUpModule, ResourceLoaderWikiModule, ResourceLoaderUserOptionsModule, and ResourceLoaderUserTokensModule.

Definition at line 125 of file ResourceLoaderModule.php.

ResourceLoaderModule::getScriptURLsForDebug ( ResourceLoaderContext $ context )

Get the URL or URLs to load for this module's JS in debug mode.

The default behavior is to return a load.php?only=scripts URL for the module, but file-based modules will want to override this to load the files directly.

This function is called only when 1) we're in debug mode, 2) there is no only= parameter and 3) supportsURLLoading() returns true. #2 is important to prevent an infinite loop, therefore this function MUST return either an only= URL or a non-load.php URL.

Parameters:

$context ResourceLoaderContext: Context object

Returns:: Array of URLs

Reimplemented in ResourceLoaderFileModule.

Definition at line 144 of file ResourceLoaderModule.php.

References $url, ResourceLoaderContext\getLanguage(), getName(), ResourceLoaderContext\getRequest(), ResourceLoaderContext\getSkin(), ResourceLoaderContext\getUser(), ResourceLoaderContext\getVersion(), and ResourceLoader\makeLoaderURL().

Here is the call graph for this function:

ResourceLoaderModule::getSource ( )

Get the origin of this module.

Should only be overridden for foreign modules.

Returns:: String: Origin name, 'local' for local modules

Definition at line 231 of file ResourceLoaderModule.php.

ResourceLoaderModule::getStyles ( ResourceLoaderContext $ context )

Get all CSS for this module for a given skin.

Parameters:

$context ResourceLoaderContext: Context object

Returns:: Array: List of CSS strings keyed by media type

Reimplemented in ResourceLoaderFileModule, ResourceLoaderWikiModule, and ResourceLoaderUserCSSPrefsModule.

Definition at line 175 of file ResourceLoaderModule.php.

ResourceLoaderModule::getStyleURLsForDebug ( ResourceLoaderContext $ context )

Get the URL or URLs to load for this module's CSS in debug mode.

The default behavior is to return a load.php?only=styles URL for the module, but file-based modules will want to override this to load the files directly. See also getScriptURLsForDebug()

Parameters:

$context ResourceLoaderContext: Context object

Returns:: Array: array( mediaType => array( URL1, URL2, ... ), ... )

Reimplemented in ResourceLoaderFileModule.

Definition at line 189 of file ResourceLoaderModule.php.

References $url, ResourceLoaderContext\getLanguage(), getName(), ResourceLoaderContext\getRequest(), ResourceLoaderContext\getSkin(), ResourceLoaderContext\getUser(), ResourceLoaderContext\getVersion(), and ResourceLoader\makeLoaderURL().

Here is the call graph for this function:

ResourceLoaderModule::isKnownEmpty ( ResourceLoaderContext $ context )

Check whether this module is known to be empty.

If a child class has an easy and cheap way to determine that this module is definitely going to be empty, it should override this method to return true in that case. Callers may optimize the request for this module away if this function returns true.

Parameters:

$context ResourceLoaderContext: Context object

Returns:: Boolean

Reimplemented in ResourceLoaderWikiModule.

Definition at line 381 of file ResourceLoaderModule.php.

static ResourceLoaderModule::javaScriptParser ( ) [static, protected]

Returns:: JSParser

Here is the caller graph for this function:

ResourceLoaderModule::setFileDependencies	(	$	skin,
		$	deps
	)

Set preloaded file dependency information.

Used so we can load this information for all modules at once.

Parameters:

$skin	String: Skin name
$deps	Array: Array of file names

Definition at line 310 of file ResourceLoaderModule.php.

ResourceLoaderModule::setMsgBlobMtime	(	$	lang,
		$	mtime
	)

Set a preloaded message blob last modification timestamp.

Used so we can load this information for all modules at once.

Parameters:

$lang	String: Language code
$mtime	Integer: UNIX timestamp or 0 if there is no such blob

Definition at line 347 of file ResourceLoaderModule.php.

ResourceLoaderModule::setName ( $ name )

Set this module's name.

This is called by ResourceLodaer::register() when registering the module. Other code should not call this.

Parameters:

$name String: Name

Definition at line 83 of file ResourceLoaderModule.php.

References $name.

ResourceLoaderModule::setOrigin ( $ origin )

Set this module's origin.

This is called by ResourceLodaer::register() when registering the module. Other code should not call this.

Parameters:

$origin Int origin

Definition at line 104 of file ResourceLoaderModule.php.

References $origin.

ResourceLoaderModule::supportsURLLoading ( )

Whether this module supports URL loading.

If this function returns false, getScript() will be used even in cases (debug mode, no only param) where getScriptURLsForDebug() would normally be used instead.
