isLessThan(_:)

Returns a Boolean value that indicates whether the receiver is less than another given object.

The object with which to compare the receiver.

Return Value

YES if the receiver is less than object, otherwise NO.

Discussion

During the evaluation of an NSWhoseSpecifier object that contains a test whose operator is NSLessThanComparison, an isLessThan(_:) message may be sent to each potentially specified object, if the potentially specified object does not implement a scriptingIsLessThan(_:) method and the object being tested against does not implement a scriptingIsGreaterThanOrEqual(to:) method.

The default implementation for this method provided by NSObject method returns YES if a compare: message sent to the same object would return NSOrderedAscending.
