The getter looks good. Yes, it will generate a warning. You can set the SuppressAllWarnings annotation to hide them - I can't remember the exact syntax.
The setter should take an NSArray, which will also allow an NSMutableArray to be passed since it is a subclass.

Hi All,
Just wondering how people are writing their accessor methods inside their EOs now that NSArray and NSMutableArray have been parameterized (did I say that right? :-) ). For example consider the following accessors for a to-many relationship called "records". Is this the right way to do it because line #7 is still generating a warning in eclipse. And what is the correct type for the setRecords() method? Should it take an NSMutableArray<Record> or an NSArray<Record> argument?
1: public void setRecords(NSMutableArray<Record> value) {
2: takeStoredValueForKey(value, "records");
3: }
4:
5:
6: public NSArray<Record> records() {
7: return ((NSArray<Record>)storedValueForKey("records"));
8: }
9:
10:
11: public void addToRecords(Record value) {
12: includeObjectIntoPropertyWithKey(value, "records");
13: }
14:
15:
16: public void removeFromRecords(Record value) {
17: excludeObjectFromPropertyWithKey(value, "records");
18: }
