Detailed Description

Represents a page (or page fragment) title within MediaWiki.

Note: In contrast to Title, this is designed to be a plain value object. That is, it is immutable, does not use global state, and causes no side effects.

Stability: newable

See also: https://www.mediawiki.org/wiki/Requests_for_comment/TitleValue

Since: 1.23

Definition at line 40 of file TitleValue.php.

Constructor & Destructor Documentation

◆ __construct()

TitleValue::__construct	(	$namespace,
		$title,
		$fragment = '',
		$interwiki = '' )

Construct a TitleValue.

Note: TitleValue expects a valid namespace and name; typically, a TitleValue is constructed either from a database entry, or by a TitleParser. For constructing a TitleValue from user input or external sources, use a TitleParser.

Stability: stable: to call

Parameters

int	$namespace	The namespace ID. This is not validated.
string	$title	The page title in either DBkey or text form. No normalization is applied beyond underscore/space conversion.
string	$fragment	The fragment title. Use '' to represent the whole page. No validation or normalization is applied.
string	$interwiki	The interwiki component. No validation or normalization is applied.

Exceptions

InvalidArgumentException

Member Function Documentation

◆ __toString()

TitleValue::__toString ( )

Returns a string representation of the title, for logging.

This is purely informative and must not be used programmatically. Use the appropriate TitleFormatter to generate the correct string representation for a given use.

Since: 1.23

Returns: string

Implements MediaWiki\Linker\LinkTarget.

Definition at line 243 of file TitleValue.php.

◆ assertValidSpec()

static TitleValue::assertValidSpec	(	$namespace,
		$title,
		$fragment = '',
		$interwiki = '' )

static

Assert that the given parameters could be used to construct a TitleValue object.

Performs basic syntax and consistency checks. Does not perform full validation, use TitleParser::makeTitleValueSafe() for that.

Parameters

int	$namespace
string	$title
string	$fragment
string	$interwiki

Exceptions

InvalidArgumentException if the combination of parameters is not valid for constructing a TitleValue.

Definition at line 165 of file TitleValue.php.

References $title, and NS_MAIN.

◆ castPageToLinkTarget()

static TitleValue::castPageToLinkTarget ( ?PageReference $page )

static

Casts a PageReference to a LinkTarget.

If $page is null, null is returned. If $page is also an instance of LinkTarget, $page is returned unchanged.

See also: newFromPage()

Since: 1.37

Parameters

PageReference | null $page

Returns: LinkTarget|null

Definition at line 118 of file TitleValue.php.

◆ createFragmentTarget()

TitleValue::createFragmentTarget ( string $fragment )

Create a new LinkTarget with a different fragment on the same page.

It is expected that the same type of object will be returned, but the only requirement is that it is a LinkTarget.

Since: 1.27

Parameters

string $fragment The fragment override, or "" to remove it.

Returns: LinkTarget

Implements MediaWiki\Linker\LinkTarget.

Definition at line 218 of file TitleValue.php.

◆ getDBkey()

TitleValue::getDBkey ( )

Get the main part of the link target, in canonical database form.

The main part is the link target without namespace prefix or hash fragment. The database form means that spaces become underscores, this is also used for URLs.

Since: 1.27

Returns: string

Implements MediaWiki\Linker\LinkTarget.

Definition at line 210 of file TitleValue.php.

Referenced by newFromPage().

◆ getFragment()

TitleValue::getFragment ( )

Get the link fragment in text form (i.e.

the bit after the hash #).

Since: 1.27

Returns: string link fragment

Implements MediaWiki\Linker\LinkTarget.

Definition at line 202 of file TitleValue.php.

◆ getInterwiki()

TitleValue::getInterwiki ( )

The interwiki component of this LinkTarget.

Since: 1.27

Returns: string

Implements MediaWiki\Linker\LinkTarget.

Definition at line 231 of file TitleValue.php.

◆ getNamespace()

TitleValue::getNamespace ( )

Get the namespace index.

Since: 1.27

Returns: int Namespace index

Implements MediaWiki\Linker\LinkTarget.

Definition at line 194 of file TitleValue.php.

Referenced by newFromPage().

◆ getText()

TitleValue::getText ( )

Get the main part of the link target, in text form.

The main part is the link target without namespace prefix or hash fragment. The text form is used for display purposes.

This is computed from the DB key by replacing any underscores with spaces.

Note: To get a title string that includes the namespace and/or fragment, use a TitleFormatter.

Since: 1.27

Returns: string

Implements MediaWiki\Linker\LinkTarget.

Definition at line 214 of file TitleValue.php.

◆ hasFragment()

TitleValue::hasFragment ( )

Whether the link target has a fragment.

Since: 1.27

Returns: bool

Implements MediaWiki\Linker\LinkTarget.

Definition at line 206 of file TitleValue.php.

◆ inNamespace()

TitleValue::inNamespace ( int $ns )

Convenience function to check if the target is in a given namespace.

Since: 1.27

Parameters

int $ns

Returns: bool

Implements MediaWiki\Linker\LinkTarget.

Definition at line 198 of file TitleValue.php.

◆ isExternal()

TitleValue::isExternal ( )

Whether this LinkTarget has an interwiki component.

Since: 1.27

Returns: bool

Implements MediaWiki\Linker\LinkTarget.

Definition at line 227 of file TitleValue.php.

◆ isSameLinkAs()

TitleValue::isSameLinkAs ( LinkTarget $other )

Check whether the given LinkTarget refers to the same target as this LinkTarget.

Two link targets are considered the same if they have the same interwiki prefix, are in the same namespace, have the same main part, and the same fragment.

Since: 1.36

Parameters

LinkTarget $other

Returns: bool

Implements MediaWiki\Linker\LinkTarget.

Definition at line 257 of file TitleValue.php.

◆ newFromPage()

static TitleValue::newFromPage ( PageReference $page )

static

Create a TitleValue from a local PageReference.

Note: The PageReference may belong to another wiki. In that case, the resulting TitleValue is also logically bound to that other wiki. No attempt is made to map the PageReference wiki ID to an interwiki prefix for the TitleValue.

Since: 1.36

Parameters

PageReference $page

Returns: TitleValue

Definition at line 103 of file TitleValue.php.

References getDBkey(), and getNamespace().

◆ tryNew()

static TitleValue::tryNew	(	$namespace,
		$title,
		$fragment = '',
		$interwiki = '' )

static

Constructs a TitleValue, or returns null if the parameters are not valid.

Note: This does not perform any normalization, and only basic validation. For full normalization and validation, use TitleParser::makeTitleValueSafe().

Parameters

int	$namespace	The namespace ID. This is not validated.
string	$title	The page title in either DBkey or text form. No normalization is applied beyond underscore/space conversion.
string	$fragment	The fragment title. Use '' to represent the whole page. No validation or normalization is applied.

Returns: TitleValue|null
