Maybe it's not as hard as it sounds? Keep in mind that right now
when you say "Load the list of EO's into memory to be processed as
raw-rows with the PK in the raw rows." I have NO idea what you're
talking about.
When you set the flag on the fetch spec to fetch raw rows the pk keys
are included in the results. e.g., if your primary key is called 'id'
then:
rawResultRow.objectForKey("id") will get your pk value.
You can use the editing context (and EOUtilities) to turn the raw row
back into a regular eo.
Now .. you might also want to have a look at Wonder's
ERXFetchSpecificationBatchIterator.
e.g.,
ERXFetchSpecificationBatchIterator iter = new
ERXFetchSpecificationBatchIterator(someRegularFetchSpec, ec,
yourBatchSize);
while (iter.hasNext()) {
NSArray stuff = iter.nextBatch();
// do stuff
ec.saveChanges();
iter.setEditingContext(ERXEC.newEditingContext());
}
with regards,
