Class Summary

ERXArrayUtilities	Collection of NSArray utilities.
ERXArrayUtilities.AvgNonNullOperator	Define an NSArray.Operator for the key avgNonNull. This allows for key value paths like: myArray.valueForKey("@avgNonNull.revenue"); which will sum up all values and divide by the number of nun-null entries.
ERXArrayUtilities.FetchSpecOperator	Define an NSArray.Operator for the key fetchSpec. This allows for key value paths like: myArray.valueForKey("@fetchSpec.fetchUsers"); Which in this case would return myArray filtered and sorted by the EOFetchSpecification named "fetchUsers" which must be a model-based fetchspec in the first object's entity.
ERXArrayUtilities.FlattenOperator	Define an NSArray.Operator for the key flatten. This allows for key value paths like: myArray.valueForKey("@flatten"); Which in this case would return myArray flattened if myArray is an NSArray of NSArrays (of NSArrays etc).
ERXArrayUtilities.IsEmptyOperator	Define an NSArray.Operator for the key isEmpty. This allows for key value paths like: myArray.valueForKey("@isEmpty");
ERXArrayUtilities.LimitOperator	Define an NSArray.Operator for the key limit, which is similar to subarrayWithRange except that it is always from 0 to the limit value.
ERXArrayUtilities.MedianOperator	Define an NSArray.Operator for the key median. This allows for key value paths like: myArray.valueForKey("@median.someMorePath"); which return the median of the array elements at the given key path.
ERXArrayUtilities.ObjectAtIndexOperator	Define an NSArray.Operator for the key objectAtIndex. This allows for key value paths like: myArray.valueForKey("@objectAtIndex.3.firstName");
ERXArrayUtilities.RemoveNullValuesOperator	Define an NSArray.Operator for the key removeNullValues. This allows for key value paths like: myArray.valueForKeyPath("@removeNullValues.someOtherPath"); Which in this case would return myArray without the occurrences of NSKeyValueCoding.Null.
ERXArrayUtilities.ReverseOperator	Define an NSArray.Operator for the key reverse. This allows for key value paths like: myArray.valueForKey("@reverse.someMorePath"); which return a reversed result as to you would normally get.
ERXArrayUtilities.SortOperator	Define an NSArray.Operator for the key sort. This allows for key value paths like: myArray.valueForKey("@sort.firstName"); myArray.valueForKey("@sort.lastName,firstName"); Which in the first case would return myArray sorted ascending by first name and the second case by lastName and then by firstName.
ERXArrayUtilities.SubarrayWithRangeOperator	Define an NSArray.Operator for the key subarrayWithRange. This allows for key value paths like: myArray.valueForKeyPath("@subarrayWithRange.20-3.name"); Note that the syntax is slightly misleading, implying that you provide a start and end index.
ERXArrayUtilities.UniqueOperator	Define an NSArray.Operator for the key unique. This allows for key value paths like: myArray.valueForKeyPath("@unique.someOtherPath"); Which in this case would return only those objects which are unique in myArray.
