__construct (User $user, WebRequest $request, IContextSource $uiContext, PermissionManager $permissionManager, RateLimiter $rateLimiter, BlockErrorFormatter $blockErrorFormatter)

authorizeAction (string $action, PermissionStatus $status=null)

Authorize an action.This should be used immediately before performing the action.Calling this method may have non-trivial side-effects, such as incrementing a rate limit counter.

Since: 1.41

See also: isDefinitelyAllowed; authorizeRead; authorizeWrite

Parameters

string	$action
PermissionStatus \| null	$status	aggregator for failures

Returns: bool

authorizeRead (string $action, PageIdentity $target, PermissionStatus $status=null)

Authorize read access.This should be used immediately before performing read access on restricted information.Calling this method may have non-trivial side-effects, such as incrementing a rate limit counter.

Parameters

string	$action
PageIdentity	$target
PermissionStatus \| null	$status	aggregator for failures

Returns: bool If the user can perform the action

See also: authorizeAction; authorizeWrite; definitelyCan

authorizeWrite (string $action, PageIdentity $target, PermissionStatus $status=null)

Authorize write access.This should be used immediately before updating persisted information.Calling this method may have non-trivial side-effects, such as incrementing a rate limit counter.

Parameters

string	$action
PageIdentity	$target
PermissionStatus \| null	$status	aggregator for failures

Returns: bool If the user can perform the action

See also: authorizeAction; authorizeRead; definitelyCan

definitelyCan (string $action, PageIdentity $target, PermissionStatus $status=null)

Checks whether this authority can perform the given action on the given target page.This method performs a thorough check, but does not protect against race conditions. It is intended to be used when a user is intending to perform an action, but has not yet committed to it. For example, when a user goes to the edit page of an article, this method may be used to determine whether the user should be presented with a warning and a read-only view instead.This method may apply rate limit checks and evaluate user blocks.

See also: probablyCan; isDefinitelyAllowed

Parameters

string	$action
PageIdentity	$target
PermissionStatus \| null	$status	aggregator for failures

Returns: bool

getBlock (int $freshness=IDBAccessObject::READ_NORMAL)

Returns any user block affecting the Authority.

Parameters

int $freshness Indicates whether slightly stale data is acceptable in, exchange for a fast response.

Returns: ?Block

Since: 1.37

getUser ()

Returns the performer of the actions associated with this authority.Actions performed under this authority should generally be attributed to the user identity returned by this method.

Returns: UserIdentity

isAllowed (string $permission, PermissionStatus $status=null)

Checks whether this authority has the given permission in general.For some permissions, exceptions may exist, both positive and negative, on a per-target basis. This method offers a fast, lightweight check, but may produce false positives. It is intended for determining which UI elements should be offered to the user.This method will not apply rate limit checks or evaluate user blocks.

Parameters

string	$permission
PermissionStatus \| null	$status

Returns: bool

See also: isDefinitelyAllowed; probablyCan

isAllowedAll (... $permissions)

Checks whether this authority has any of the given permissions in general.Implementations must ensure that this method returns false if isAllowed would return false for any of the given permissions. Calling isAllowedAll() with one parameter must be equivalent to calling isAllowed(). Calling isAllowedAny() with no parameter is not allowed.

See also: isAllowed

Parameters

string ...$permissions Permissions to test. At least one must be given.

Returns: bool True if the user is allowed to perform all of the given actions

isAllowedAny (... $permissions)

Checks whether this authority has any of the given permissions in general.Implementations must ensure that this method returns true if isAllowed would return true for any of the given permissions. Calling isAllowedAny() with one parameter must be equivalent to calling isAllowed(). Calling isAllowedAny() with no parameter is not allowed.

See also: isAllowed

Parameters

string ...$permissions Permissions to test. At least one must be given.

Returns: bool True if user is allowed to perform any of the given actions

isDefinitelyAllowed (string $action, PermissionStatus $status=null)

Checks whether this authority is allowed to perform the given action.This method performs a thorough check, but does not protect against race conditions. It is intended to be used when a user is intending to perform an action, but has not yet committed to it. For example, when a user visits their preferences page, this method may be used to determine whether the user should have the option to change their email address.This method may apply rate limit checks and evaluate user blocks.

Since: 1.41

See also: isAllowed; definitelyCan

Parameters

string	$action
PermissionStatus \| null	$status	aggregator for failures

Returns: bool

isNamed ()

Is the user a normal non-temporary registered user?

isRegistered ()

Get whether the user is registered.

isTemp ()

Is the user an autocreated temporary user?

limit (string $action, int $incrBy, ?PermissionStatus $status)

Check whether a rate limit has been exceeded for the given action.

probablyCan (string $action, PageIdentity $target, PermissionStatus $status=null)

Checks whether this authority can probably perform the given action on the given target page.This method offers a fast, lightweight check, but may produce false positives. It is intended for determining which UI elements should be offered to the user. This method will not apply rate limit checks or evaluate user blocks.

See also: definitelyCan; isAllowed

Parameters

string	$action
PageIdentity	$target
PermissionStatus \| null	$status	aggregator for failures

Returns: bool

setUseLimitCache (bool $useLimitCache)

Detailed Description

Represents the authority of a given User.

For anonymous visitors, this will typically allow only basic permissions. For logged in users, permissions are generally based on group membership, but may be adjusted based on things like IP range blocks, OAuth grants, or rate limits.

Note: This is intended as an intermediate step towards an implementation of Authority that contains much of the logic currently in PermissionManager, and is based directly on WebRequest and Session, rather than a User object. However, for now, code that needs an Authority that reflects the current user and web request should use a User object directly.

Stability: unstable
