Discussion 解説

During the evaluation of an NSWhoseSpecifier object that contains a test whose operator is NSLessThanOrEqualToComparison, an isLessThanOrEqualTo: message may be sent to each potentially specified object, if the potentially specified object does not implement a scriptingIsLessThanOrEqualTo: method and the object being tested against does not implement a scriptingIsGreaterThan: 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 or NSOrderedSame.
