Constructor & Destructor Documentation

◆ __construct()

AbstractContent::__construct ( $modelId = null )

Stable to call.

Parameters

string | null $modelId

Since: 1.21

Reimplemented in WikitextContent.

Definition at line 57 of file AbstractContent.php.

Member Function Documentation

◆ addSectionHeader()

AbstractContent::addSectionHeader ( $header )

Stable to override.

Since: 1.21

Parameters

string $header

Returns: Content $this

See also: Content::addSectionHeader

Implements Content.

Reimplemented in WikitextContent.

Definition at line 451 of file AbstractContent.php.

◆ checkFormat()

AbstractContent::checkFormat ( $format )

protected

Since: 1.21

Parameters

string $format The serialization format to check.

Exceptions

MWException If the format is not supported by this content handler.

Definition at line 150 of file AbstractContent.php.

◆ checkModelID()

AbstractContent::checkModelID ( $modelId )

protected

Since: 1.21

Parameters

string $modelId The model to check

Exceptions

MWException If the provided ID is not the ID of the content model supported by this Content object.

Definition at line 79 of file AbstractContent.php.

Referenced by TextContent\diff().

◆ convert()

AbstractContent::convert	(		$toModel,
			$lossy = '' )

This base implementation calls the hook ConvertContent to enable custom conversions.

Subclasses may override this to implement conversion for "their" content model.

Stable to override

Parameters

string	$toModel
string	$lossy

Returns: Content|bool

See also: Content::convert()

Implements Content.

Reimplemented in TextContent, and UnknownContent.

Definition at line 537 of file AbstractContent.php.

◆ equals()

AbstractContent::equals ( Content $that = null )

Decides whether two Content objects are equal.

Two Content objects MUST not be considered equal if they do not share the same content model. Two Content objects that are equal SHOULD have the same serialization.

This default implementation relies on equalsInternal() to determin whether the Content objects are logically equivalent. Subclasses that need to implement a custom equality check should consider overriding equalsInternal(). Subclasses that override equals() itself MUST make sure that the implementation returns false for $that === null, and true for $that === this. It MUST also return false if $that does not have the same content model.

Stable to override

Since: 1.21

Parameters

Content | null $that

Returns: bool

See also: Content::equals

Implements Content.

Definition at line 220 of file AbstractContent.php.

Referenced by CssContent\getRedirectTarget(), and JavaScriptContent\getRedirectTarget().

◆ equalsInternal()

AbstractContent::equalsInternal ( Content $that )

protected

Checks whether $that is logically equal to this Content object.

This method can be overwritten by subclasses that need to implement custom equality checks.

This default implementation checks whether the serializations of $this and $that are the same: $this->serialize() === $that->serialize()

Implementors can assume that $that is an instance of the same class as the present Content object, as long as equalsInternal() is only called by the standard implementation of equals().

Note: Do not call this method directly, call equals() instead.

Stable to override

Parameters

Content $that

Returns: bool

Reimplemented in UnknownContent.

Definition at line 261 of file AbstractContent.php.

References Content\serialize(), and serialize().

◆ fillParserOutput()

AbstractContent::fillParserOutput	(	Title	$title,
			$revId,
		ParserOptions	$options,
			$generateHtml,
		ParserOutput &	$output )

protected

Fills the provided ParserOutput with information derived from the content.

Unless $generateHtml was false, this includes an HTML representation of the content.

This is called by getParserOutput() after consulting the ContentGetParserOutput hook. Subclasses are expected to override this method (or getParserOutput(), if need be). Subclasses of TextContent should generally override getHtml() instead.

This placeholder implementation always throws an exception.

Stable to override

Since: 1.24

Parameters

Title	$title	Context title for parsing
int \| null	$revId	ID of the revision being rendered. See Parser::parse() for the ramifications.
ParserOptions	$options
bool	$generateHtml	Whether or not to generate HTML
ParserOutput	&$output	The output object to fill (reference).

Exceptions

MWException

Reimplemented in JsonContent, TextContent, UnknownContent, and WikitextContent.

Definition at line 623 of file AbstractContent.php.

◆ getContentHandler()

AbstractContent::getContentHandler ( )

Since: 1.21

See also: Content::getContentHandler

Returns: ContentHandler

Implements Content.

Definition at line 95 of file AbstractContent.php.

References getContentHandlerFactory(), and getModel().

Referenced by CssContent\getRedirectTarget(), JavaScriptContent\getRedirectTarget(), CssContent\updateRedirect(), and JavaScriptContent\updateRedirect().

◆ getContentHandlerFactory()

AbstractContent::getContentHandlerFactory ( )

Returns: IContentHandlerFactory

Definition at line 102 of file AbstractContent.php.

Referenced by TextContent\convert(), and getContentHandler().

◆ getDefaultFormat()

AbstractContent::getDefaultFormat ( )

Since: 1.21

See also: Content::getDefaultFormat

Returns: string

Implements Content.

Definition at line 112 of file AbstractContent.php.

◆ getDeletionUpdates()

AbstractContent::getDeletionUpdates	(	WikiPage	$page,
		ParserOutput	$parserOutput = null )

Stable to override.

Since: 1.21

Parameters

WikiPage	$page
ParserOutput \| null	$parserOutput

Returns: DeferrableUpdate[]

See also: Content::getDeletionUpdates

Implements Content.

Definition at line 501 of file AbstractContent.php.

◆ getModel()

AbstractContent::getModel ( )

Since: 1.21

See also: Content::getModel

Returns: string

Implements Content.

Definition at line 67 of file AbstractContent.php.

References $model_id.

Referenced by TextContent\fillParserOutput(), UnknownContent\fillParserOutput(), getContentHandler(), TextContent\preSaveTransform(), and WikitextContent\replaceSection().

◆ getParserOutput()

AbstractContent::getParserOutput	(	Title	$title,
			$revId = null,
		ParserOptions	$options = null,
			$generateHtml = true )

Returns a ParserOutput object containing information derived from this content.

Most importantly, unless $generateHtml was false, the return value contains an HTML representation of the content.

Subclasses that want to control the parser output may override this, but it is preferred to override fillParserOutput() instead.

Subclasses that override getParserOutput() itself should take care to call the ContentGetParserOutput hook.

Stable to override

Since: 1.24

Parameters

Title	$title	Context title for parsing
int \| null	$revId	Revision ID being rendered
ParserOptions \| null	$options
bool	$generateHtml	Whether or not to generate HTML

Returns: ParserOutput Containing information derived from this content.

Implements Content.

◆ getSecondaryDataUpdates()

AbstractContent::getSecondaryDataUpdates	(	Title	$title,
		Content	$old = null,
			$recursive = true,
		ParserOutput	$parserOutput = null )

Returns a list of DataUpdate objects for recording information about this Content in some secondary data store.

This default implementation returns a LinksUpdate object and calls the SecondaryDataUpdates hook.

Subclasses may override this to determine the secondary data updates more efficiently, preferably without the need to generate a parser output object. They should however make sure to call SecondaryDataUpdates to give extensions a chance to inject additional updates.

Stable to override

Since: 1.21

Parameters

Title	$title
