public function ConflictResolverManager::resolveConflicts in Conflict 8.2

Resolves the conflicts between two entities based on their common parent.

Parameters

\Drupal\Core\Entity\EntityInterface $local: The local part of the comparision - for example the entity built of the user input on an entity form submission. This is basically the active entity object.

\Drupal\Core\Entity\EntityInterface $remote: The remote part of the comparision - for example the current version of the entity from the storage or from a remote branch.

\Drupal\Core\Entity\EntityInterface $base: The initial entity version in concurrent editing or the lowest common ancestor in a revision tree scenario.

\Drupal\Core\Entity\EntityInterface $result: (optional) The result entity, on which to apply the result. Usually this will be the active entity object - the local entity. If none given, then the conflict resolutions will be applied on the local entity.

\Symfony\Component\HttpFoundation\ParameterBag $context: (optional) The context parameter bag.

array $conflicts: (optional) The conflicts as returned by ::getConflicts() or a sub-set of them in order to limit the conflict resolution only to certain conflicts. If none conflicts are provided then a conflict detection will be performed.

Return value

array An associative array keyed by the conflicting properties, having as values the corresponding conflict type.
