Actually, there is no difference between a property and a pair of getter/setter methods. Here you have defined a write-only property, and since you have this method, you could write:
o.maximumOperations=42;
as well as:
[o setMaximumOperations:42]
The same code is generated in both cases.
If you added a method -(NSInteger)maximumOperations then you'd have a read-write property.
You can call it a derived property, since it is not implemented directly as a slot of your instances.
