Detailed Description

Base implementation for content objects.

Definition at line 34 of file AbstractContent.php.

Constructor & Destructor Documentation

◆ __construct()

AbstractContent::__construct ( $modelId = null )

Parameters

string $modelId

Since: 1.21

Reimplemented in RevisionTestModifyableContent, WikitextContent, GadgetDefinitionContent, DummyContentForTesting, and DummyNonTextContent.

Definition at line 50 of file AbstractContent.php.

Member Function Documentation

◆ addSectionHeader()

AbstractContent::addSectionHeader ( $header )

Since: 1.21

Parameters

string $header

Returns: Content $this

See also: Content::addSectionHeader

Implements Content.

Reimplemented in WikitextContent.

Definition at line 386 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 136 of file AbstractContent.php.

References getModel(), and isSupportedFormat().

◆ 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 72 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.

Parameters

string	$toModel
string	$lossy

Returns: Content|bool

See also: Content::convert()

Implements Content.

Reimplemented in TextContent.

Definition at line 466 of file AbstractContent.php.

References getModel(), and Hooks\run().

◆ equals()

AbstractContent::equals ( Content $that = null )

Since: 1.21

Parameters

Content $that

Returns: bool

See also: Content::equals

Implements Content.

Definition at line 191 of file AbstractContent.php.

References getModel(), and Content\getNativeData().

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

◆ 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.

Since: 1.24

Parameters

Title	$title	Context title for parsing
int \| null	$revId	Revision ID (for {{REVISIONID}})
ParserOptions	$options	Parser options
bool	$generateHtml	Whether or not to generate HTML
ParserOutput	&$output	The output object to fill (reference).

Exceptions

MWException

Reimplemented in WikitextContent, TextContent, DummyContentForTesting, DummyNonTextContent, JsonContent, and GadgetDefinitionContent.

◆ getContentHandler()

AbstractContent::getContentHandler ( )

Since: 1.21

See also: Content::getContentHandler

Returns: ContentHandler

Implements Content.

Definition at line 88 of file AbstractContent.php.

References ContentHandler\getForContent().

Referenced by GadgetDefinitionContent\getAssocArray(), getDefaultFormat(), getParserOutput(), CssContent\getRedirectTarget(), JavaScriptContent\getRedirectTarget(), getSupportedFormats(), isSupportedFormat(), serialize(), CssContent\updateRedirect(), and JavaScriptContent\updateRedirect().

◆ getDefaultFormat()

AbstractContent::getDefaultFormat ( )

Since: 1.21

See also: Content::getDefaultFormat

Returns: string

Implements Content.

Definition at line 98 of file AbstractContent.php.

References getContentHandler().

◆ getDeletionUpdates()

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

Since: 1.21

Parameters

WikiPage	$page
ParserOutput \| null	$parserOutput

Returns: LinksDeletionUpdate[]

See also: Content::getDeletionUpdates

Implements Content.

Reimplemented in GadgetDefinitionContent.

Definition at line 433 of file AbstractContent.php.

◆ getModel()

AbstractContent::getModel ( )

Since: 1.21

See also: Content::getModel

Returns: string

Implements Content.

Definition at line 60 of file AbstractContent.php.

References $model_id.

Referenced by checkFormat(), convert(), equals(), TextContent\fillParserOutput(), 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.

Since: 1.24

Parameters

Title	$title	Context title for parsing
int \| null	$revId	Revision ID (for {{REVISIONID}})
ParserOptions \| null	$options	Parser options
bool	$generateHtml	Whether or not to generate HTML

Returns: ParserOutput Containing information derived from this content.

Implements Content.

Reimplemented in MessageContent, DummyContentForTesting, and DummyNonTextContent.

◆ getRedirectChain()

AbstractContent::getRedirectChain ( )

Since: 1.21

Returns: Title[]|null

See also: Content::getRedirectChain

Implements Content.

◆ getRedirectTarget()

AbstractContent::getRedirectTarget ( )

Subclasses that implement redirects should override this.

Since: 1.21

Returns: Title|null

See also: Content::getRedirectTarget

Implements Content.

Reimplemented in WikitextContent, JavaScriptContent, and CssContent.

Definition at line 292 of file AbstractContent.php.

Referenced by getParserOutput(), getRedirectChain(), and isRedirect().

◆ 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.
