	__construct (int $namespace, string $dbKey, $wikiId)

	__toString ()
	Returns a string representation of the title, for logging.

	getDBkey ()
	Get the page title in DB key form. Note This may return a string starting with a hash, if the PageReference represents the target of a block or unblock operation. This is due to the way the block target is represented in the logging table. This is intended to change in the future. This may return an empty string, if this PageReference is a Title that represents a relative section link. This is intended to change in the future. Returns string

	getNamespace ()
	Returns the page's namespace number.The value returned by this method should represent a valid namespace, but this cannot be guaranteed in all cases. Returns int

	getWikiId ()
	Get the ID of the wiki provided to the constructor.

Detailed Description

Immutable value object representing a page identity.

Instances of this class are expected to always represent proper pages, that is, pages that can at least potentially exist as editable pages on the wiki. This class cannot represent Special pages, interwiki links, section links, etc.

Code that deserializes instances of PageIdentityValue must ensure that the original meaning of the "local" Wiki ID is preserved: When an instance of PageIdentityValue is created with self::LOCAL as the Wiki ID on one wiki, gets serialized, stored, and later read and unserialized on another wiki, the value of the Wiki ID must be adjusted to refer to the original wiki.

Since: 1.36

Constructor & Destructor Documentation

◆ __construct()

MediaWiki\Page\PageIdentityValue::__construct	(	int	$pageId,
		int	$namespace,
		string	$dbKey,
			$wikiId )

Parameters

int	$pageId	The ID of this page, or 0 if the page does not exist.
int	$namespace	A valid namespace ID. Validation is the caller's responsibility!
string	$dbKey	A valid DB key. Validation is the caller's responsibility!
string \| false	$wikiId	The Id of the wiki this page belongs to, or self::LOCAL for the local wiki.

Member Function Documentation

◆ canExist()

MediaWiki\Page\PageIdentityValue::canExist ( )

Returns: bool always true

Implements MediaWiki\Page\ProperPageIdentity.

Definition at line 129 of file PageIdentityValue.php.

◆ exists()

MediaWiki\Page\PageIdentityValue::exists ( )

Returns whether the page currently exists.

Returns true if getId() returns a value greater than zero.

Returns: bool

Implements MediaWiki\Page\PageIdentity.

Definition at line 122 of file PageIdentityValue.php.

◆ getId()

MediaWiki\Page\PageIdentityValue::getId ( $wikiId = self::LOCAL )

The numerical page ID provided to the constructor.

Parameters

string | false $wikiId The wiki ID expected by the caller. Omit if expecting the local wiki.

Returns: int

Implements MediaWiki\Page\ProperPageIdentity.

Definition at line 112 of file PageIdentityValue.php.

◆ localIdentity()

static MediaWiki\Page\PageIdentityValue::localIdentity	(	int	$pageId,
		int	$namespace,
		string	$dbKey )

static

Create PageIdentity for a local page.

Parameters

int	$pageId
int	$namespace
string	$dbKey

Returns: PageIdentityValue

Definition at line 100 of file PageIdentityValue.php.

◆ tryNew()

static MediaWiki\Page\PageIdentityValue::tryNew	(	int	$pageId,
		int	$namespace,
		string	$dbKey,
			$wikiId )

static

Constructs a PageIdentityValue, 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() together with PageLookup::getPageForLink().

Parameters

int	$pageId	The ID of this page, or 0 if the page does not exist.
int	$namespace	A valid namespace ID. Validation is the caller's responsibility!
string	$dbKey	A valid DB key. Validation is the caller's responsibility!
string \| false	$wikiId	The Id of the wiki this page belongs to, or self::LOCAL for the local wiki.

Returns: PageIdentityValue|null
