  • Train image index.

    Declaration

    Objective-C

    @property int imgIdx;

    Swift

    var imgIdx: Int32 { get set }

  • Distance

    Declaration

    Objective-C

    @property float distance;

    Swift

    var distance: Float { get set }

  • Declaration

  • Compare for equality

    Declaration

    Objective-C

    - (BOOL)isEqual:(nullable id)other;

    Swift

    func isEqual(_ other: Any?) -> Bool

    Parameters

    other

    Object to compare

  • Calculate hash for this object

    Declaration

    Objective-C

    - (NSUInteger)hash;

    Swift

    func hash() -> UInt

  • Returns a string that describes the contents of the object
