| 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: }
