Constructor & Destructor Documentation

__construct()

Preprocessor::__construct	(	Parser	$parser,
		WANObjectCache	$wanCache = null,
		array	$options = [] )

Parameters

Parser	$parser
WANObjectCache | null	$wanCache
array	$options	Map of additional options, including: disableLangConversion: disable language variant conversion. [Default: false]

Reimplemented in Preprocessor_Hash.

Member Function Documentation

newCustomFrame()

Preprocessor::newCustomFrame ( $args )

abstract

Create a new custom frame for programmatic use of parameter replacement.

This is useful for certain types of extensions

Parameters

array

$args

Returns

PPFrame

Reimplemented in Preprocessor_Hash.

newFrame()

Preprocessor::newFrame ( )

abstract

Create a new top-level frame for expansion of a page.

Returns

PPFrame

Reimplemented in Preprocessor_Hash.

newPartNodeArray()

Preprocessor::newPartNodeArray ( $values )

abstract

Create a new custom node for programmatic use of parameter replacement.

This is useful for certain types of extensions

Parameters

array

$values

Reimplemented in Preprocessor_Hash.

preprocessToObj()

Preprocessor::preprocessToObj ( $text, $flags = 0 )

abstract

Get the document object model for the given wikitext.

Any flag added to the $flags parameter here, or any other parameter liable to cause a change in the DOM tree for the given wikitext, must be passed through the section identifier in the section edit link and thus back to extractSections().

Parameters

string	$text	Wikitext
int	$flags	Bit field of Preprocessor::DOM_* flags: Preprocessor::DOM_FOR_INCLUSION: treat the wikitext as transcluded content from a page rather than direct content of a page or message. By default, the text is assumed to be undergoing processing for use by direct page views. The use of this flag causes text within <noinclude> tags to be ignored, text within <includeonly> to be included, and text outside of <onlyinclude> to be ignored. Preprocessor::DOM_NO_LANG_CONV: do not parse "-{ ... }-" constructs, which are involved in language variant conversion. (deprecated since 1.36) Preprocessor::DOM_UNCACHED: disable use of the preprocessor cache.

Returns

PPNode

Reimplemented in Preprocessor_Hash.

resetParser()

Preprocessor::resetParser

(

?Parser

$parser

)

Allows resetting the internal Parser reference after Preprocessor is cloned.

Do not use this function in new code, since this method will be moved once Parser cloning goes away (T250448)

Parameters

?Parser

$parser

Access: internal

Definition at line 95 of file Preprocessor.php.

References $parser.
