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 452 of file AbstractContent.php.

◆ checkFormat()

AbstractContent::checkFormat (   $format)
protected
Since
1.21
Parameters
string$formatThe serialization format to check.
Exceptions
MWExceptionIf the format is not supported by this content handler.

Definition at line 150 of file AbstractContent.php.

References getModel(), and isSupportedFormat().

◆ checkModelID()

AbstractContent::checkModelID (   $modelId)
protected
Since
1.21
Parameters
string$modelIdThe model to check
Exceptions
MWExceptionIf the provided ID is not the ID of the content model supported by this Content object.

◆ 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 FallbackContent.

Definition at line 538 of file AbstractContent.php.

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

◆ 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.

References equalsInternal().

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 FallbackContent.

◆ 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$titleContext title for parsing
int | null$revIdID of the revision being rendered. See Parser::parse() for the ramifications.
ParserOptions$options
bool$generateHtmlWhether or not to generate HTML
ParserOutput&$outputThe output object to fill (reference).
Exceptions
MWException

Reimplemented in WikitextContent, TextContent, JsonContent, and FallbackContent.

◆ getContentHandlerFactory()

AbstractContent::getContentHandlerFactory ( )

Returns

See also
Content::getDefaultFormat
Returns
string

Implements Content.

◆ 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 502 of file AbstractContent.php.

◆ getModel()

AbstractContent::getModel ( )

◆ 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$titleContext title for parsing
int | null$revIdRevision ID being rendered
ParserOptions | null$options
bool$generateHtmlWhether or not to generate HTML
Returns
ParserOutput Containing information derived from this content.

◆ getRedirectTarget()

AbstractContent::getRedirectTarget ( )

Subclasses that implement redirects should override this.

Stable to override

Returns
Title|null

Content::getRedirectTarget

◆ 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$title
Content | null$old
bool$recursive
ParserOutput | null$parserOutput
