Detailed Description

Base implementation for content objects.

Stability: stable: to extend

Definition at line 45 of file AbstractContent.php.

Constructor & Destructor Documentation

◆ __construct()

AbstractContent::__construct ( $modelId = null )

Stability: stable: to call

Parameters

string | null $modelId

Since: 1.21

Reimplemented in WikitextContent.

Definition at line 63 of file AbstractContent.php.

Member Function Documentation

◆ addSectionHeader()

AbstractContent::addSectionHeader ( $header )

Stability: stable: to override

Since: 1.21

Parameters

string $header

Returns: Content $this

See also: Content::addSectionHeader

Implements Content.

Reimplemented in WikitextContent.

Definition at line 432 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 156 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 85 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.

Stability: stable: to override

Parameters

string	$toModel
string	$lossy

Returns: Content|false

See also: Content::convert()

Implements Content.

Reimplemented in FallbackContent, and TextContent.

Definition at line 525 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 determine 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.

Stability: stable: to override

Since: 1.21

Parameters

Content | null $that

Returns: bool

See also: Content::equals

Implements Content.

Definition at line 247 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.

Stability: stable: to override

Parameters

Content $that

Returns: bool

Reimplemented in FallbackContent.

Definition at line 288 of file AbstractContent.php.

References Content\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.

Since: 1.24

Deprecated: since 1.38. Hard-deprecated since 1.38. Use ContentHandler::fillParserOutput instead.

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

Since: 1.21

See also: Content::getDefaultFormat

Returns: string

Implements Content.

Definition at line 118 of file AbstractContent.php.

◆ getModel()

AbstractContent::getModel ( )

Since: 1.21

See also: Content::getModel

Returns: string

Implements Content.

Definition at line 73 of file AbstractContent.php.

References $model_id.

Referenced by getContentHandler(), and WikitextContent\replaceSection().

◆ getNativeData()

AbstractContent::getNativeData ( )

Returns native representation of the data.

Interpretation depends on the data model used, as given by getDataModel().

Stability: stable: to override

Since: 1.21

Deprecated: since 1.33 use getText() for TextContent instances. For other content models, use specialized getters.

Returns: mixed The native representation of the content. Could be a string, a nested array structure, an object, a binary blob... anything, really.

Exceptions

LogicException

Note: Caller must be aware of content model!

Implements Content.

Reimplemented in FallbackContent, MessageContent, and TextContent.

Definition at line 196 of file AbstractContent.php.

◆ 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

Deprecated: since 1.38. Hard-deprecated since 1.38. Use ContentRenderer::getParserOutput instead. Extensions defining a content model should override ContentHandler::fillParserOutput.

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.
