Member Function Documentation

◆ centralIdFromLocalUser()

CentralIdLookup::centralIdFromLocalUser	(	User	$user,
			$audience = `self::AUDIENCE_PUBLIC`,
			$flags = `self::READ_NORMAL`
	)

Given a local User object, return the central ID Stable to override.

Note: Unlike centralIdFromName(), this does guarantee that the local user is attached to the central account.

Parameters

User	$user	Local user
int \| User	$audience	One of the audience constants, or a specific user
int	$flags	IDBAccessObject read flags

Returns: int User ID; 0 if the local user does not correspond to a central user, $audience lacks the rights needed to see it, or the central user isn't locally attached.

Definition at line 289 of file CentralIdLookup.php.

References User\getName().

◆ centralIdFromName()

CentralIdLookup::centralIdFromName	(	$name,
		$audience = `self::AUDIENCE_PUBLIC`,
		$flags = `self::READ_NORMAL`
	)

Given a (local) user name, return the central ID.

Note: There's no requirement that the user name actually exists locally, or if it does that it's actually attached to the central account.

Parameters

string	$name	Canonicalized user name
int \| User	$audience	One of the audience constants, or a specific user
int	$flags	IDBAccessObject read flags

Returns: int User ID; 0 if the name does not correspond to a user or $audience lacks the rights needed to see it.

Definition at line 224 of file CentralIdLookup.php.

◆ centralIdsFromNames()

CentralIdLookup::centralIdsFromNames	(	array	$names,
			$audience = `self::AUDIENCE_PUBLIC`,
			$flags = `self::READ_NORMAL`
	)

Given an array of (local) user names, return the central IDs.

Parameters

string[]	$names	Canonicalized user names
int \| User	$audience	One of the audience constants, or a specific user
int	$flags	IDBAccessObject read flags

Returns: int[] User IDs

Since: 1.30

Definition at line 239 of file CentralIdLookup.php.

◆ checkAudience()

CentralIdLookup::checkAudience ( $audience )

protected

Check that the "audience" parameter is valid.

Parameters

int | User $audience One of the audience constants, or a specific user

Returns: User|null User to check against, or null if no checks are needed

Exceptions

InvalidArgumentException

◆ factory()

static CentralIdLookup::factory ( $providerId = null )

static

Fetch a CentralIdLookup.

Parameters

string | null $providerId Provider ID from $wgCentralIdLookupProviders

Returns: CentralIdLookup|null

Definition at line 47 of file CentralIdLookup.php.

◆ factoryNonLocal()

static CentralIdLookup::factoryNonLocal ( )

static

Returns a CentralIdLookup that is guaranteed to be non-local.

If no such guarantee can be made, returns null.

If this function returns a non-null CentralIdLookup, that lookup is expected to provide IDs that are shared with some set of other wikis. However, you should still be cautious when using those IDs, as they will not necessarily work with all other wikis, and it can be hard to tell if another wiki is in the same set as this one or not.

Since: 1.35

Returns: CentralIdLookup|null

Definition at line 83 of file CentralIdLookup.php.

References factory().

◆ getProviderId()

CentralIdLookup::getProviderId ( )

final

Definition at line 110 of file CentralIdLookup.php.

◆ isAttached()

CentralIdLookup::isAttached	(	User	$user,
			$wikiId = `null`
	)

abstract

Check that a User is attached on the specified wiki.

If unattached local accounts don't exist in your extension, this comes down to a check whether the central account exists at all and that $wikiId is using the same central database.

Parameters

User	$user
string \| null	$wikiId	Wiki to check attachment status. If null, check the current wiki.

Returns: bool

Reimplemented in LocalIdLookup.

◆ localUserFromCentralId()

CentralIdLookup::localUserFromCentralId	(	$id,
		$audience = `self::AUDIENCE_PUBLIC`,
		$flags = `self::READ_NORMAL`
	)

Given a central user ID, return a local User object.

Note: Unlike nameFromCentralId(), this does guarantee that the local user exists and is attached to the central account. Stable to override

Parameters

int	$id	Central user ID
int \| User	$audience	One of the audience constants, or a specific user
int	$flags	IDBAccessObject read flags

Returns: User|null Local user, or null if: $id doesn't correspond to a user, $audience lacks the rights needed to see the user, the user doesn't exist locally, or the user isn't locally attached.

◆ lookupCentralIds()

CentralIdLookup::lookupCentralIds	(	array	$idToName,
			$audience = `self::AUDIENCE_PUBLIC`,
			$flags = `self::READ_NORMAL`
	)

abstract

Given central user IDs, return the (local) user names.

Note: There's no requirement that the user names actually exist locally, or if they do that they're actually attached to the central account.

Parameters

array	$idToName	Array with keys being central user IDs
int \| User	$audience	One of the audience constants, or a specific user
int	$flags	IDBAccessObject read flags

Returns: array Copy of $idToName with values set to user names (or empty-string if the user exists but $audience lacks the rights needed to see it). IDs not corresponding to a user are unchanged.

Reimplemented in LocalIdLookup.

◆ lookupUserNames()

CentralIdLookup::lookupUserNames	(	array	$nameToId,
			$audience = `self::AUDIENCE_PUBLIC`,
			$flags = `self::READ_NORMAL`
	)

abstract

Given (local) user names, return the central IDs.

Note: There's no requirement that the user names actually exist locally, or if they do that they're actually attached to the central account.

Parameters

array	$nameToId	Array with keys being canonicalized user names
int \| User	$audience	One of the audience constants, or a specific user
int	$flags	IDBAccessObject read flags

Returns: array Copy of $nameToId with values set to central IDs. Names not corresponding to a user (or $audience lacks the rights needed to see it) are unchanged.
