Class TimeChecker

java.lang.Object
  jas.statistics.TimeChecker

public class TimeChecker
extends java.lang.Object

The time checker is used by all the classes implementing the IUpdatableSource interface to avoid repetitive updates.
Every time the updateSource method of the user class is invoked, it asks to TimeChecker if the update has been done yet at the current simulation time.
If the time checker is disabled it force the users to always update themselves.
