Constructor Details

PeriodicTimer

public PeriodicTimer(ScheduledExecutorService executorService)

Initializes a new instance of the PeriodicTimer class.

Parameters:

executorService - The ScheduledExecutorService used to schedule the timer's events.

Throws:

IllegalArgumentException - The executorService is a null reference or initialDelay is smaller than zero or period is smaller than or equal to zero.

Method Details

setListener

public void setListener(TimerListener listener)

Sets the TimerListener observation used to observe this Timer implementation

Specified by:

setListener in interface Timer

Parameters:

listener - The TimerListener instance used to observe this Timer or a null reference.

scheduleOneShot

public void scheduleOneShot(org.joda.time.Duration delay)

Schedules an one-time event to be trigger after time interval specified by passed Duration. Any events scheduled by previous calls to either Timer.scheduleOneShot(org.joda.time.Duration) or Timer.schedule(org.joda.time.Duration, org.joda.time.Duration) are un-scheduled by this call.

Specified by:

scheduleOneShot in interface Timer

Parameters:

delay - Specifies the time interval after which the one shot event will be triggered.

Throws:

IllegalArgumentException - The delay is a null reference.

schedule

public void schedule(org.joda.time.Duration initialDelay,
 org.joda.time.Duration period)

Schedules a periodic event with specified initialDelay and period. Any events scheduled by previous calls to either Timer.scheduleOneShot(org.joda.time.Duration) or Timer.schedule(org.joda.time.Duration, org.joda.time.Duration) are un-scheduled by this call.

Specified by:

schedule in interface Timer

Parameters:

initialDelay - Specifies the time interval after which the one shot event will be triggered.

period - Specifies the timer period.

Throws:

IllegalArgumentException - The initialDelay is a null reference or period is a null reference.

stop

public void stop()

Un-schedules any events previously registered with calls to Timer.scheduleOneShot(org.joda.time.Duration) or Timer.schedule(org.joda.time.Duration, org.joda.time.Duration). If no events were scheduled it does nothing.

Specified by:

stop in interface Timer
