active

Arguments: timer

A boolean value indicating whether a timer is currently running. An active timer fires each time its interval passes, while an inactive timer does nothing. This property of a timer will be true if start-timer has been called on the timer more recently than stop-timer has. If the active property is explicitly modified by an application from nil to true, then start-timer is called internally, and if the active property is explicitly modified from true to nil, then stop-timer is called internally. Therefore, in order to wrap all starting and stopping of timers, it is sufficient to add start-timer and stop-timer methods.

active is a property of the timer class.

See cg-timers.htm for more information on timers.
