Constructor & Destructor Documentation

◆ __construct()

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.

Parameters

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

Reimplemented from ContentHandler.

Definition at line 34 of file TextContentHandler.php.

Member Function Documentation

◆ getContentClass()

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: string

Reimplemented in CodeContentHandler, JavaScriptContentHandler, CssContentHandler, JsonContentHandler, WikitextContentHandler, and GadgetDefinitionContentHandler.

Definition at line 103 of file TextContentHandler.php.

References class.

Referenced by makeEmptyContent(), and unserializeContent().

◆ getDataForSearchIndex()

TextContentHandler::getDataForSearchIndex	(	WikiPage	$page,
		ParserOutput	$output,
		SearchEngine	$engine
	)

Return fields to be indexed by search engine as representation of this document.

Overriding class should call parent function or take care of calling the SearchDataForIndex hook.

Parameters

SearchEngine	$engine	Search engine for which we are indexing

Returns: array Map of name=>value for fields

◆ getFieldsForSearchIndex()

TextContentHandler::getFieldsForSearchIndex ( SearchEngine $engine )

Get fields definition for search index.

Todo:: Expose title, redirect, namespace, text, source_text, text_bytes field mappings here. (see T142670 and T143409)

Parameters

◆ merge3()

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.

Returns: Content|bool

TextContentHandler::serializeContent	(	Content	$content,
			$format = `null`
	)

Returns the content's text as-is.

Parameters

Content	$content
string	$format	The serialization format to check

Returns: mixed
