module Hyrax

module NestedCollectionPersistenceService
# @api public
#
# Responsible for persisting the relationship between the parent and the child.
# @see Hyrax::Collections::NestedCollectionQueryService
#
# @param parent [Collection]
# @param child [Collection]
# @note There is odd permission arrangement based on the NestedCollectionQueryService:
# You can nest the child within a parent if you can edit the parent and read the child.
# See https://wiki.duraspace.org/display/samvera/Samvera+Tech+Call+2017-08-23 for tech discussion.
# @note Adding the member_of_collections method doesn't trigger reindexing of the child so we have to do it manually.
# However it save and reindexes the parent unnecessarily!!

# @note Removing the member_of_collections method doesn't trigger reindexing of the child so we have to do it manually.
# However it doesn't save and reindex the parent, as it does when a parent is added!!
