def find_children_of(destroyed_id:)

end

#reindex_extent ⇒ Object

The following methods allow an option to reindex an object only if the nesting indexer fields are not already in the object’s solr document. Added to prevent unnecessary indexing of all ancestors of a parent when one child gets added to the parent. By default, we do the full graph indexing.

#use_nested_reindexing? ⇒ Boolean

Only models which include Hyrax::CollectionNesting will respond to this method. Used to determine whether a model gets reindexed via Samvera::NestingIndexer during full repository reindexing,

Returns:
