ORKTrailmakingTap Class Reference

Inherits from NSObject
Conforms to NSCopying
Declared in ORKTrailmakingResult.h

The ORKTrailmakingTap class represents a single tap in a trail making test.

The Trailmaking tap move object records the indexes of tap, if it was in error or not and the time at which the event occurred. A trailmakingTap instance is included in an ORKTrailmakingResult object and is recorded by the step view controller for the corresponding task when a tap is made.

A trail making tap is typically generated by the framework as the task proceeds. When the task completes, it may be appropriate to serialize the move for transmission to a server, or to immediately perform analysis on it.


A relative timestamp indicating the time of the tap event.

@property (nonatomic, assign) NSTimeInterval timestamp


The timestamp is relative to the value of startDate in the ORKResult object that includes this move. The start date of that object represents the time at which the first move was made.
