Or, if you do have a lot of objects that you look up often from your
cache, upon loading:
NSMutableDictionary personBySSN = new NSMutableDictionary();
In loop:
personBySSN.setObjectForKey(person, person.ssn());
Then to lookup:
person = (Person) personBySSN.objectForKey(ssn);
Of course, you should only do this with keys that you know are always
there, and always unique...

or if you use Wonder:
NSArray<Something> results = ERXQ.filtered(array, qualifier);

I'm thinking this is a newbie question, but I can't seem to find an
answer in the docs (likely I'm reading them incorrectly).
Situation:
I'm pulling objects into an NSArray to reduce multiple lookups later.
So, I have these objects and I want to do a lookup of one object in
the NSArray. But all I have is the value of one element of the
object in the array.
Example:
NSArray anArray = EOUtilities...; // gets about 1,000 person
objects from the database
Now I'd like to find a single object in anArray based on SSN.
It seems that anArray.indexOfObject( object ); is intended to do
this but I don't have the object, I only have an identifier for the
object.
I'm sure this is handled, but am out of channels to research.
Thanks
