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

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

Unlike centralIdFromName(), this does guarantee that the local user is attached to the central account.
Parameters
User$userLocal user
int | User$audienceOne of the audience constants, or a specific user
int$flagsIDBAccessObject 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.

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.

◆ factory()

◆ 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

◆ 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$user
string | null$wikiIdWiki to check attachment status. If null, check the current wiki.
Returns
bool

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$idCentral user ID
int | User$audienceOne of the audience constants, or a specific user
int$flagsIDBAccessObject 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.

abstract

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

Note
