Member Function Documentation

◆ assignFreshId()

Wikibase\Lib\Store\EntityStore::assignFreshId ( EntityDocument $entity )

Assigns a fresh ID to the given entity.

Note: The new ID is "consumed" after this method returns, and will not be assigned to another other entity. The next available ID for each kind of entity is considered part of the persistent state of the Wikibase installation.; calling this method on an Entity that already has an ID, and specifically calling this method twice on the same entity, shall result in an exception.

Parameters

EntityDocument $entity

Exceptions

StorageException

Implemented in Wikibase\Lib\Store\TypeDispatchingEntityStore, Wikibase\Repo\EditEntity\StatsdSaveTimeRecordingEntityStore, and Wikibase\Repo\Store\Sql\WikiPageEntityStore.

◆ canCreateWithCustomId()

Wikibase\Lib\Store\EntityStore::canCreateWithCustomId ( EntityId $id )

Whether an entity with the given custom ID can exist.

Implementations are not required to check if an entity with the given ID already exists. If this method returns true, this means that an entity with the given ID could be created (or already existed) at the time the method was called. There is no guarantee that this continues to be true after the method call returned. Callers must be careful to handle race conditions.

See also: EntityHandler::canCreateWithCustomId

Parameters

EntityId $id

Returns: bool

Implemented in Wikibase\Lib\Store\TypeDispatchingEntityStore, Wikibase\Repo\EditEntity\StatsdSaveTimeRecordingEntityStore, and Wikibase\Repo\Store\Sql\WikiPageEntityStore.

◆ deleteEntity()

Wikibase\Lib\Store\EntityStore::deleteEntity	(	EntityId	$entityId,
			$reason,
		User	$user
	)

Deletes the given entity in some underlying storage mechanism.

Parameters

EntityId	$entityId
string	$reason	the reason for deletion
User	$user

Exceptions

StorageException
PermissionsError

Implemented in Wikibase\Lib\Store\TypeDispatchingEntityStore, Wikibase\Repo\EditEntity\StatsdSaveTimeRecordingEntityStore, and Wikibase\Repo\Store\Sql\WikiPageEntityStore.

◆ isWatching()

Wikibase\Lib\Store\EntityStore::isWatching	(	User	$user,
		EntityId	$id
	)

Determines whether the given user is watching the given item.

Todo:: move this to a separate service

Parameters

User	$user
EntityId	$id	the entity to watch

Returns: bool

Implemented in Wikibase\Lib\Store\TypeDispatchingEntityStore, Wikibase\Repo\EditEntity\StatsdSaveTimeRecordingEntityStore, and Wikibase\Repo\Store\Sql\WikiPageEntityStore.

◆ saveEntity()

Wikibase\Lib\Store\EntityStore::saveEntity	(	EntityDocument	$entity,
			$summary,
		User	$user,
			$flags = `0`,
			$baseRevId = `false`,
		array	$tags = `[]`
	)

Saves the given Entity to some underlying storage mechanism.

Note: If the item does not have an ID yet (i.e. it was not yet created in the database), saveEntity() will fail with a edit-gone-missing message unless the EDIT_NEW bit is set in $flags. If EDIT_NEW is set and the Entity does not yet have an ID, a new ID is assigned using assignFreshId().; if the save is triggered by any kind of user interaction, consider using EditEntity::attemptSave(), which automatically handles edit conflicts, permission checks, etc.

Parameters

EntityDocument	$entity	the entity to save.
string	$summary	the edit summary for the new revision.
User	$user	the user to whom to attribute the edit
int	$flags	EDIT_XXX flags, as defined for WikiPage::doEditContent. Additionally, the EntityContent::EDIT_XXX constants can be used.
int \| bool	$baseRevId	the revision ID $entity is based on. Saving should fail if $baseRevId is no longer the current revision.
string[]	$tags	Change tags to add to the edit. Callers are responsible for permission checks (typically using `ChangeTags::canAddTagsAccompanyingChange`).

See also: WikiPage::doEditContent

Returns: EntityRevision

Exceptions

StorageException
PermissionsError

Implemented in Wikibase\Lib\Store\TypeDispatchingEntityStore, Wikibase\Repo\EditEntity\StatsdSaveTimeRecordingEntityStore, and Wikibase\Repo\Store\Sql\WikiPageEntityStore.

◆ saveRedirect()

Wikibase\Lib\Store\EntityStore::saveRedirect	(	EntityRedirect	$redirect,
			$summary,
		User	$user,
			$flags = `0`,
			$baseRevId = `false`
	)

Saves the given EntityRedirect to some underlying storage mechanism.

Parameters

EntityRedirect	$redirect	the redirect to save.
string	$summary	the edit summary for the new revision.
User	$user	the user to whom to attribute the edit
int	$flags	EDIT_XXX flags, as defined for WikiPage::doEditContent.
int \| bool	$baseRevId	the revision ID $entity is based on. Saving should fail if $baseRevId is no longer the current revision.

See also: WikiPage::doEditContent

Returns: int The new revision ID

Exceptions

StorageException
PermissionsError

Implemented in Wikibase\Lib\Store\TypeDispatchingEntityStore, Wikibase\Repo\EditEntity\StatsdSaveTimeRecordingEntityStore, and Wikibase\Repo\Store\Sql\WikiPageEntityStore.

◆ updateWatchlist()

Wikibase\Lib\Store\EntityStore::updateWatchlist	(	User	$user,
		EntityId	$id,
			$watch
	)

Watches or unwatches the entity.

Todo:: move this to a separate service

Parameters

User	$user
EntityId	$id	the entity to watch
bool	$watch	whether to watch or unwatch the page.

Exceptions

MWException

◆ userWasLastToEdit()

Wikibase\Lib\Store\EntityStore::userWasLastToEdit	(	User	$user,
		EntityId	$id,
			$lastRevId
	)

Check if no edits were made by other users since the given revision.

This makes the assumption that revision ids are monotonically increasing.

See also: EditPage::userWasLastToEdit()

Parameters

User	$user
EntityId	$id	the entity to check
int	$lastRevId	the revision to check from

Returns: bool

Implemented in Wikibase\Lib\Store\TypeDispatchingEntityStore, Wikibase\Repo\EditEntity\StatsdSaveTimeRecordingEntityStore, and Wikibase\Repo\Store\Sql\WikiPageEntityStore.
