Member Function Documentation

◆ getDefinitionMtime()

ResourceLoaderModule::getDefinitionMtime ( ResourceLoaderContext $context )

Helper method for calculating when this module's definition summary was last changed.

Returns: integer: UNIX timestamp or 0 if no definition summary was provided by getDefinitionSummary()

Definition at line 447 of file ResourceLoaderModule.php.

References $cache, $hash, $summary, $timestamp, CACHE_ANYTHING, getDefinitionSummary(), getName(), wfDebugLog(), wfGetCache(), wfMemcKey(), wfProfileIn(), and wfProfileOut().

Referenced by ResourceLoaderWikiModule\getModifiedTime(), and ResourceLoaderFileModule\getModifiedTime().

◆ getDefinitionSummary()

ResourceLoaderModule::getDefinitionSummary ( ResourceLoaderContext $context )

Get the definition summary for this module.

This is the method subclasses should implement if they want to make use of getDefinitionMTime() inside getModifiedTime().

Return an array containing values from all significant properties of this module's definition. Be sure to include things that are explicitly ordered, in their actaul order (bug 37812).

Avoid including things that are insiginificant (e.g. order of message keys is insignificant and should be sorted to avoid unnecessary cache invalidation).

Avoid including things already considered by other methods inside your getModifiedTime(), such as file mtime timestamps.

Serialisation is done using json_encode, which means object state is not taken into account when building the hash. This data structure must only contain arrays and scalars as values (avoid object instances) which means it requires abstraction.

Returns: Array|null

Reimplemented in ResourceLoaderFileModule, and ResourceLoaderWikiModule.

Definition at line 510 of file ResourceLoaderModule.php.

References array().

Referenced by getDefinitionMtime().

◆ getDependencies()

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.

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, ResourceLoaderLanguageDataModule, ResourceLoaderUserCSSPrefsModule, and ResourceLoaderTestModule.

Definition at line 283 of file ResourceLoaderModule.php.

References array().

◆ getFileDependencies()

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

string $skin Skin name

Returns: array: List of files

◆ getHashMtime()

ResourceLoaderModule::getHashMtime ( ResourceLoaderContext $context )

Helper method for calculating when the module's hash (if it has one) changed.

Parameters

ResourceLoaderContext $context

Returns: integer: UNIX timestamp or 0 if no hash was provided by getModifiedHash()

Definition at line 404 of file ResourceLoaderModule.php.

References $cache, $hash, $timestamp, array(), CACHE_ANYTHING, getModifiedHash(), getName(), wfGetCache(), wfMemcKey(), and wfTimestamp().

◆ getLoaderScript()

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 268 of file ResourceLoaderModule.php.

◆ getMessages()

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

References array().

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

◆ getModifiedHash()

ResourceLoaderModule::getModifiedHash ( ResourceLoaderContext $context )

Get the hash for whatever this module may contain.

This is the method subclasses should implement if they want to make use of getHashMTime() inside getModifiedTime().

Parameters

ResourceLoaderContext $context

Returns: string|null: Hash

Reimplemented in ResourceLoaderStartUpModule, and ResourceLoaderLanguageDataModule.

Definition at line 437 of file ResourceLoaderModule.php.

Referenced by getHashMtime().

◆ getModifiedTime()

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.

NOTE: The mtime of the module's hash is NOT automatically included. If your module provides a getModifiedHash() method, you'll need to call getHashMtime() yourself and take its result into consideration.

Parameters

ResourceLoaderContext $context Context object

Returns: integer UNIX timestamp

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

Definition at line 392 of file ResourceLoaderModule.php.

◆ getMsgBlobMtime()

ResourceLoaderModule::getMsgBlobMtime ( $lang )

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

Parameters

string $lang Language code

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

◆ getName()

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

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

Returns: int: ResourceLoaderModule class constant, the subclass default if not set manually

Definition at line 97 of file ResourceLoaderModule.php.

References $origin.

Referenced by OutputPage\filterModules().

◆ getPosition()

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 248 of file ResourceLoaderModule.php.

◆ getScript()

Parameters

ResourceLoaderContext $context

Returns: string: JavaScript code

◆ getScriptURLsForDebug()

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

ResourceLoaderContext $context

Returns: array: Array of URLs

Reimplemented in ResourceLoaderFileModule.

Definition at line 147 of file ResourceLoaderModule.php.

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