Method Detail

initialize

public static final Timer initialize(TimerManager mgr,
                                     Date startTime,
                                     long repeatIntervalMinutes)
                              throws Exception

Initializes this timer listener. Use this method to create the timer instance of the announcement poller. You should hold on to the reference of the timer for future use (i.e. so that you can cancel it).

Parameters

mgr - The timer manager to use to create the timer listener.

startTime - The date/time of the first timerExpired callback. ** Required **

repeatIntervalMinutes - The interval (in minutes) in which the callback is invoked after startTime. Valid values are 0 <= repeatIntervalMinutes <= 1440(24 hours). A value of 0 will cause the timer to execute once, at startTime. ** Required **

Returns

The timer instance. The reference to this should be retained until such time as the timer should be cancelled.
