Detailed Description

Base content handler implementation for flat text contents.

Definition at line 44 of file TextContentHandler.php.

Constructor & Destructor Documentation

◆ __construct()

MediaWiki\Content\TextContentHandler::__construct	(		$modelId = CONTENT_MODEL_TEXT,
			$formats = [ CONTENT_FORMAT_TEXT ] )

Constructor, initializing the ContentHandler instance with its model ID and a list of supported formats.

Values for the parameters are typically provided as literals by subclass's constructors.

Stability: stable: to call

Parameters

string	$modelId	(use CONTENT_MODEL_XXX constants).
string[]	$formats	List for supported serialization formats (typically as MIME types)

Reimplemented from MediaWiki\Content\ContentHandler.

Definition at line 46 of file TextContentHandler.php.

Member Function Documentation

◆ fillParserOutput()

MediaWiki\Content\TextContentHandler::fillParserOutput	(	Content	$content,
		ContentParseParams	$cpoParams,
		ParserOutput &	$output )

protected

Fills the provided ParserOutput object with information derived from the content.

Unless $generateHtml was false, this includes an HTML representation of the content provided by getHtml().

For content models listed in $wgTextModelsToParse, this method will call the MediaWiki wikitext parser on the text to extract any (wikitext) links, magic words, etc., but note that the Table of Contents will not be generated (feature added by T307691, but should be refactored: T313455).

Subclasses may override this to provide custom content processing. For custom HTML generation alone, it is sufficient to override getHtml().

Stability: stable: to override

Since: 1.38

Parameters

Content	$content
ContentParseParams	$cpoParams
ParserOutput	&$output	The output object to fill (reference).

◆ getContentClass()

MediaWiki\Content\TextContentHandler::getContentClass ( )

protected

Returns the name of the associated Content class, to be used when creating new objects.

Override expected by subclasses.

Since: 1.24

Returns: class-string<TextContent>

◆ merge3()

MediaWiki\Content\TextContentHandler::merge3	(	Content	$oldContent,
		Content	$myContent,
		Content	$yourContent )

Attempts to merge differences between three versions.

Returns a new Content object for a clean merge and false for failure or a conflict.

All three Content objects passed as parameters must have the same content model.

This text-based implementation uses wfMerge().

Parameters

Content	$oldContent	The page's previous content.
Content	$myContent	One of the page's conflicting contents.
Content	$yourContent	One of the page's conflicting contents.
