ISCIComparable Protocol Reference


                        
                        
                        -compareTo:

Returns an NSComparisonResult value that indicates whether the number object’s value is greater than, equal to, or less than a given ISCIComparable.

Declaration

Objective-C

- (NSComparisonResult)compareTo:(nonnull NSObject *)obj;

Swift

func compare(to obj: NSObject) -> ComparisonResult

Return Value

NSOrderedAscending if the value of aNumber is greater than the number object’s, NSOrderedSame if they’re equal, and NSOrderedDescending if the value of obj is less than the number object’s.


                        
                        
                        -toDouble

Converts this comparable iinstalce to primitive double value.

Declaration

Objective-C

- (double)toDouble;

Swift

func toDouble() -> Double

Return Value

Unboxed primitive value of the this ISCIComparable instance.


                        
                        
                        -toDate

Converts this comparable instance to NSDate

Declaration

Objective-C

- (nonnull NSDate *)toDate;

Swift

func toDate() -> Date

Return Value

The converted NSDate instance.


                        
                        
                        -toComparable

Needed to be able to cast implementors to ISCIComparable on Xamarin.iOS side, since it’s impossible there.

Declaration

Objective-C

- (nonnull id<ISCIComparable>)toComparable;

Swift

func to() -> ISCIComparable


                        
                        
                        isDefined

Checks whether this ISCIComparable instance is defined.

Declaration

Objective-C

@property (nonatomic, readonly) BOOL isDefined;

Swift

var isDefined: Bool { get }
