Constructor & Destructor Documentation

__construct()

Wikibase\Repo\Api\EntitySavingHelper::__construct	(	bool	$isWriteMode,
			$needsToken,
		RevisionLookup	$revisionLookup,
		TitleFactory	$titleFactory,
		EntityIdParser	$idParser,
		EntityRevisionLookup	$entityRevisionLookup,
		EntityTitleStoreLookup	$entityTitleStoreLookup,
		ApiErrorReporter	$errorReporter,
		SummaryFormatter	$summaryFormatter,
		MediaWikiEditEntityFactory	$editEntityFactory,
		PermissionManager	$permissionManager )

Member Function Documentation

attemptSaveEntity()

Wikibase\Repo\Api\EntitySavingHelper::attemptSaveEntity	(	EntityDocument	$entity,
			$summary,
		array	$requestParams,
		IContextSource	$context,
		int	$flags = 0 )

Attempts to save the new entity content, while first checking for permissions, edit conflicts, etc.

Saving is done via EditEntityHandler::attemptSave().

This method automatically takes into account several parameters:

• 'bot' for setting the bot flag
• 'baserevid' for determining the edit's base revision for conflict resolution
• 'token' for the edit token
• 'tags' for change tags, assuming they were already permission checked by ApiBase (i.e. PARAM_TYPE => 'tags')

If an error occurs, it is automatically reported and execution of the API module is terminated using the ApiErrorReporter (via handleStatus()). If there were any warnings, they will automatically be included in the API call's output (again, via handleStatus()).

Parameters

EntityDocument	$entity	The entity to save
string | FormatableSummary	$summary	The edit summary
array	$requestParams
IContextSource	$context
int	$flags	The edit flags (see WikiPage::doEditContent)

Exceptions

LogicException

if not in write mode

Returns

Status the status of the save operation, as returned by EditEntityHandler::attemptSave()

See also

EditEntityHandler::attemptSave()

createEntity()

Wikibase\Repo\Api\EntitySavingHelper::createEntity ( ?string $entityType, ?EntityId $customId, string $assignFreshId )

private

Create an empty entity.

Parameters

string | null	$entityType	The type of entity to create. Optional if an ID is given.
EntityId | null	$customId	Optionally assigns a specific ID instead of generating a new one.
string	$assignFreshId	Either of the ASSIGN_FRESH_ID/NO_FRESH_ID constants NOTE: We usually need to assign an ID early, for things like the ClaimIdGenerator.

Exceptions

InvalidArgumentException	when entity type and ID are given but do not match.
ApiUsageException
LogicException

Returns

EntityDocument

evaluateTokenParam()

Wikibase\Repo\Api\EntitySavingHelper::evaluateTokenParam ( array $params )

private

Parameters

array

$params

Returns

string|bool|null Token string, or false if not needed, or null if not set.

handleSaveStatus()

Wikibase\Repo\Api\EntitySavingHelper::handleSaveStatus ( EditEntityStatus $status )

private

Signal errors and warnings from a save operation to the API call's output.

This is much like handleStatus(), but specialized for Status objects returned by EditEntityHandler::attemptSave(). In particular, the 'errorFlags' field from the status value is used to determine the error code to return to the caller.

Note

this function may or may not return normally, depending on whether the status is fatal or not.

See also

handleStatus().

Parameters

EditEntityStatus

$status

The status to report

handleStatus()

Wikibase\Repo\Api\EntitySavingHelper::handleStatus ( Status $status, $errorCode )

private

Include messages from a Status object in the API call's output.

An ApiErrorHandler is used to report the status, if necessary. If $status->isOK() is false, this method will terminate with an ApiUsageException.

Parameters

Status	$status	The status to report
string | null	$errorCode	The API error code to use in case $status->isOK() returns false

Exceptions

ApiUsageException

If $status->isOK() returns false.

isEntityCreationSupported()

Wikibase\Repo\Api\EntitySavingHelper::isEntityCreationSupported ( )

private

loadEntity()

Wikibase\Repo\Api\EntitySavingHelper::loadEntity	(	array	$requestParams,
		?EntityId	$entityId = null,
			$assignFreshId = self::ASSIGN_FRESH_ID )

Parameters

array	$requestParams
EntityId | null	$entityId	ID of the entity to load. If not given, the ID is taken from the request parameters. If $entityId is given, the 'baserevid' parameter must belong to it.
string	$assignFreshId	Whether to allow assigning entity ids to new entities. Either of the ASSIGN_FRESH_ID/NO_FRESH_ID constants. NOTE: We usually need to assign an ID early, for things like the ClaimIdGenerator.

Exceptions

ApiUsageException

Returns

EntityDocument
