| Hello, This is really hard to put down succinctly, so I'll try to do it a couple different ways: Is there an easy way to base the sort order of an array entities returned on an attribute of an entity related to each of the returned entities?
IOW:
startEntity to-many returnedEntity sorted by returnedEntity to-one subEntity.sortKey.
Note that the returnedEntity owns, and propogates its primary key to, the subEntity.
e.g. This was basically my first try (I'm using wonder), but since I was applying a subEntity sort key on a returnedEntity array, it of course choked.
EOSortOrdering[] sortBy = { new EOSortOrdering(subEntity.SORT_KEY, EOSortOrdering.CompareDescending)}; NSArray<EOSortOrdering> sortByArray = new NSArray<EOSortOrdering>( sortBy); // Sort
NSArray<Entry> entities = this.returnedEntity(null, sortByArray, false); Thanks! Jeff |
