Detailed Description

EntityHolder implementing deferred copying.

Copyright: GPL-2.0-or-later

Author: Daniel Kinzler

Constructor & Destructor Documentation

◆ __construct()

Wikibase\Repo\Content\DeferredCopyEntityHolder::__construct ( EntityHolder $entityHolder )

Member Function Documentation

◆ getEntity()

Wikibase\Repo\Content\DeferredCopyEntityHolder::getEntity ( $expectedClass = EntityDocument::class )

See also: EntityHolder::getEntityId

This implements lazy initialization of the entity: when called for the first time, this method will call getEntity() on the EntityHolder passed to the constructor, and then deep clone the entity returned. The resulting copy is returned. Subsequent calls will return the same entity.

Parameters

string $expectedClass The class with which the result is expected to be compatible. Defaults to EntityDocument.

Exceptions

RuntimeException If the entity held by this EntityHolder is not compatible with $expectedClass.
