TaskHandler

class TaskKit.TaskHandler.TaskHandler(scheduler, start, period, task, name)

While the Task class only knows what task to perform with the run()-method, the TaskHandler has all the knowledge about the periodicity of the task. Instances of this class are managed by the Scheduler in the scheduled, running and onDemand dictionaries.
