(informal protocol)
Declared in:
- EOControl/EOSortOrdering.h
The EOSortOrderingComparison informal protocol defines methods for comparing values. These methods are used for sorting value objects.
| Note: This interface doesn't exist in the Yellow Box package, com.apple.yellow.eocontrol |
Though declared for NSObject, most of these methods work properly only with value classes: NSString, NSDate, NSNumber, NSDecimalNumber, and EONull.
NSOrderedAscending if anObject is
naturally ordered after the receiver, NSOrderedDescending if it's
naturally ordered before the receiver, and NSOrderedSame if
they're equivalent for ordering purposes. NSObject's implementation
of this method simply invokes compare:.NSOrderedAscending if anObject is
naturally ordered-ignoring case-after the receiver, NSOrderedDescending if
it's naturally ordered before the receiver, and NSOrderedSame if
they're equivalent for ordering purposes. NSObject's implementation
of this method invokes compare:, while NSString's
invokes caseInsensitiveCompare:.NSOrderedAscending if anObject is
naturally ordered-ignoring case-before the
receiver, NSOrderedDescending if
it's naturally ordered after the
receiver, and NSOrderedSame if
they're equivalent for ordering purposes. NSObject's implementation
of this method invokes compare: and inverts
the result, while NSString's invokes caseInsensitiveCompare: and
inverts the result.NSOrderedAscending if anObject is
