Detailed Description

A registry service for SlotRoleHandlers, used to define which slot roles are available on which page.

Extensions may use the SlotRoleRegistry to register the slots they define.

In the context of the SlotRoleRegistry, it is useful to distinguish between "defined" and "known" slot roles: A slot role is "defined" if defineRole() or defineRoleWithModel() was called for that role. A slot role is "known" if the NameTableStore provided to the constructor as the $roleNamesStore parameter has an ID associated with that role, which essentially means that the role at some point has been used on the wiki. Roles that are not "defined" but are "known" typically belong to extensions that used to be installed on the wiki, but no longer are. Such slots should be considered ok for display and administrative operations, but only "defined" slots should be supported for editing.

Since: 1.33

Constructor & Destructor Documentation

◆ __construct()

MediaWiki\Revision\SlotRoleRegistry::__construct ( NameTableStore $roleNamesStore )

Parameters

NameTableStore $roleNamesStore

Member Function Documentation

◆ defineRole()

MediaWiki\Revision\SlotRoleRegistry::defineRole	(		$role,
		callable	$instantiator )

Defines a slot role.

For use by extensions that wish to define roles beyond the main slot role.

See also: defineRoleWithModel()

Parameters

string	$role	The role name of the slot to define. This should follow the same convention as message keys:
callable	$instantiator	called with $role as a parameter; Signature: function ( string $role ): SlotRoleHandler

◆ defineRoleWithModel()

MediaWiki\Revision\SlotRoleRegistry::defineRoleWithModel	(		$role,
			$model,
			$layout = [],
		bool	$derived = false )

Defines a slot role that allows only the given content model, and has no special behavior.

For use by extensions that wish to define roles beyond the main slot role, but have no need to implement any special behavior for that slot.

See also: defineRole()

Parameters

string	$role	The role name of the slot to define, see defineRole() for more information.
string	$model	A content model name, see ContentHandler
array	$layout	See SlotRoleHandler getOutputLayoutHints
bool	$derived	see SlotRoleHandler constructor

Since: 1.36 optional $derived parameter added

◆ getAllowedRoles()

MediaWiki\Revision\SlotRoleRegistry::getAllowedRoles ( PageIdentity $page )

Returns the list of roles allowed when creating a new revision on the given page.

The choice should not depend on external state, such as the page content. Note that existing revisions of that page are not guaranteed to comply with this list.

All implementations of this method are required to return at least all "required" roles.

Parameters

PageIdentity $page

Returns: string[]

Definition at line 171 of file SlotRoleRegistry.php.

◆ getDefinedRoles()

MediaWiki\Revision\SlotRoleRegistry::getDefinedRoles ( )

Returns the list of roles defined by calling defineRole().

This list should be used when enumerating slot roles that can be used for editing.

Returns: string[]

◆ getKnownRoles()

MediaWiki\Revision\SlotRoleRegistry::getKnownRoles ( )

Returns the list of known roles, including the ones returned by getDefinedRoles(), and roles that exist according to the NameTableStore provided to the constructor.

This list should be used when enumerating slot roles that can be used in queries or for display.

Returns: string[]

◆ getRequiredRoles()

MediaWiki\Revision\SlotRoleRegistry::getRequiredRoles ( PageIdentity $page )

Returns the list of roles required when creating a new revision on the given page.

The should not depend on external state, such as the page content. Note that existing revisions of that page are not guaranteed to comply with this list.

All required roles are implicitly considered "allowed", so any roles returned by this method will also be returned by getAllowedRoles().

Parameters

PageIdentity $page

Returns: string[]

◆ getRoleHandler()

MediaWiki\Revision\SlotRoleRegistry::getRoleHandler ( $role )

Gets the SlotRoleHandler that should be used when processing content of the given role.

Parameters

string $role

Exceptions

InvalidArgumentException If $role is not a known slot role.

Returns: SlotRoleHandler The handler to be used for $role. This may be a FallbackSlotRoleHandler if the slot is "known" but not "defined".

◆ isDefinedRole()

MediaWiki\Revision\SlotRoleRegistry::isDefinedRole ( $role )

Whether the given role is defined, that is, it was defined by calling defineRole().

Parameters

string $role

Returns: bool

Whether the given role is known, that is, it's either defined or exist according to the NameTableStore provided to the constructor.

Parameters

string $role

Returns: bool
