I haven't seen too much discussion on this, so I'm hoping for some
clarification/insight as to this topic. If I've missed something, I
apologize and would appreciate any pointers to any articles I missed.
Let's say I have a Survey entity, and within it are a series of
SurveyQuestion entities in a 1-to-many relationship. Now let's say that
within the Survey entity I want to use @Query on a property to grab an
ordered list of related SurveyQuestion objects.
Now, I'm fairly certain that SDN has no way of remembering my insertion
order into the graph (nor should it, really), so I have a property on the
Survey entity that denotes the order. So, I can use a Cypher query from
within @Query to get an ordered list of SurveyQuestion entities and return
them as an Iterable or List, for example.
E.g. MATCH (s:Survey)-[:SURVEY_QUESTION]->(q:SurveyQuestion) WHERE id(s) =
{self} RETURN q ORDER BY q.position
If I do that, though, I'm noticing that the objects that are returned are
NOT hydrated, i.e. I have to "fetch" each one as I use them. Is there an
easy way to hydrate them all at once? (I can't simply call fetch() on the
property.)
Or, better yet, is there a best practice or preferred way of accomplishing
what I'm after without breaking the bank in terms of overhead?
If I'm way off on anything here, I'd love to know as I get deeper still
into SDN.
Thanks!
