Hi folks,
Here is a an optimisation-related question.
My app has a user-configurable search page, which displays results
in a WODisplayGroup (10 results at a time). Depending on the search,
up to 500 complex objects can be fetched, thus the page is rather
slow to load, so I'd like to use RawRows to speed things up.
Configuring the fetch to use RawRows is a picnic, but how to convert
those raw rows 10 at a time, just before they are displayed by the
display group ?
In other words, i'd like to see the following patern:
- load 500 objects as raw rows
- convert the first 10 objects to EntrepriseObjects using
EOEditingContext faultForRawRow()
- when the user moves to the next batch of the display group, convert
the 10 next raw rows to EntrepriseObject
... and so on
Any pointers ?
Regards,
François
