def changed?
  super || ordered_self.changed?
end

#clear_changed_attributes ⇒ Object

Overriding so that we don’t track previously_changed, which was rather expensive.

Returns:

  • (Array<ListNode>)

def ordered_self
  @ordered_self ||= ordered_list_factory.new(resource, head_subject, tail_subject)
end

#ordered_self=(new_ordered_self) ⇒ Object

Allow this to be set so that -=, += will work.

Parameters:

  super
end

#serializable_hash(options = nil) ⇒ Object

Note:

This method is used by ActiveFedora::Base upstream for indexing, at github.com/projecthydra/active_fedora/blob/master/lib/active_fedora/profile_indexing_service.rb.

Serializing head/tail/nodes slows things down CONSIDERABLY, and is not useful.
