LimitOperator ()

Detailed Description

Define an NSArray.Operator for the key limit, which is similar to subarrayWithRange except it is always from 0 to the limit value. If the limit specified is larger than the size of the array, the entire array will be returned.

This allows for key value paths like:

myArray.valueForKeyPath("@limit.10.someOtherPath");

Which in this case would return the first 10 objects in myArray before continuing to process someOtherPath.
