protected function ContentEntityConflictHandler::needsMerge in Conflict 8.2

Performs a check if a merge is required.

Note that if the entity doesn't implement the EntityChangedInterface and no extended check ($extended_check = FALSE) is performed, then the method will return TRUE as there is no short way of checking for changes, in which case the extended check should be performed afterwards.

Parameters

\Drupal\Core\Entity\ContentEntityInterface $entity_local_edited: The locally edited entity.

\Drupal\Core\Entity\ContentEntityInterface $entity_local_original: The original not edited entity used to build the form.

\Drupal\Core\Entity\ContentEntityInterface $entity_server: The unchanged entity loaded from the storage.

bool $extended_check: Specifies whether an extended check should be performed.

Return value

bool TRUE if a merge is needed, FALSE otherwise.
