Constructor & Destructor Documentation

◆ __construct()

AbstractContent::__construct (   $modelId = null)
Parameters
string$modelId
Since
1.21

Reimplemented in RevisionTestModifyableContent, WikitextContent, DummyNonTextContent, and DummyContentForTesting.

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

Definition at line 136 of file AbstractContent.php.

References getModel(), and isSupportedFormat().

◆ checkModelID()

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

Definition at line 72 of file AbstractContent.php.

◆ 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.

◆ 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$titleContext title for parsing
int | null$revIdRevision ID (for {{REVISIONID}})
ParserOptions$options
bool$generateHtmlWhether or not to generate HTML
ParserOutput&$outputThe output object to fill (reference).
Exceptions
MWException

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

◆ getContentHandler()

◆ getDefaultFormat()

AbstractContent::getDefaultFormat ( )
Since
1.21
See also
Content::getDefaultFormat
Returns
string

Implements Content.

◆ getDeletionUpdates()

AbstractContent::getDeletionUpdates ( WikiPage  $page,
ParserOutput  $parserOutput = null 
)
Since
1.21
Parameters
WikiPage$page
ParserOutput | null$parserOutput
Returns
DeferrableUpdate[]
See also
Content::getDeletionUpdates

Implements Content.

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.

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

Implements Content.

Reimplemented in DummyNonTextContent, DummyContentForTesting, and MessageContent.

◆ getRedirectChain()

AbstractContent::getRedirectChain ( )

◆ 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.

◆ 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.

Since
1.21
Parameters
Title$title
Content$old
bool$recursive
ParserOutput$parserOutput
Returns
DataUpdate[]
