Hi there,
EOEntity has a restrictingQualifier that's applied to every fetch
for the relevant entity.
Is there any similar mechanism for installing a default ordering
for fetched objects of each entity (e.g., when following a toMany
relationship)? Or any delegate methods somewhere?
No. And don't override the EOF methods to do this or you risk
messing with EOF. And we all know how that ends up. :-) The reason
for the lack of sorting, as I understand it, is that EOF would then
need to keep the list sorted each time something was added to it.
And what if you wanted alternate sorts? The standard approach is to
have a cover method that sorts the contents of the relationship and
returns it.
