[Wonder-disc] EOQualifier filtering in memory

[Giles P. <li...@ce...>]

Hi

I have a relationship as follows...

transaction->>lines->>items-->account

If I construct a qualifier like...

qualifier  = ERXQ.equals("lines.items.account",anAccount)

and then use it with a fetchSpec as...

EOFetchSpecification fetchSpec = new EOFetchSpecification(_Transaction.ENTITY_NAME, qualifier, null);
fetchSpec.setUsesDistinct(true);
NSArray<Transaction> transactions = editingContext().objectsWithFetchSpecification(fetchSpec);

All works as expected and any transactions whose relationships ultimately point to "anAccount" get returned.

My problem is when I use the same qualifier to filter an existing array of transactions in memory...

qualifier  = ERXQ.equals("lines.items.account",anAccount)

NSArray<Transaction> transactions = EOQualifier.filteredArrayWithQualifier(someTransactions, qualifier);

In this case the qualifier does not seem to filter the transaction in "someTransactions" to match "anAccount".

I was expecting this to work just the same as it would when used with a fetchSpec but it doesn't.  What have I misunderstood?  Can we filter in memory like this?

Thanks

Giles
