Object compute (NSArray<?> array, String keypath)

SubarrayWithRangeOperator ()

Detailed Description

Define an NSArray.Operator for the key subarrayWithRange.

This allows for key value paths like:

myArray.valueForKeyPath("@subarrayWithRange.20-3.someOtherPath");

Which in this case would return the three objects from myArray, starting at the index of 20, before continuing to process someOtherPath.

Note that the syntax for the range argument is not startIndex-endIndex. The API matches that of NSRange. You must provide a start index and an array length.
