Constructor Detail

PeriodicTimerThread

public PeriodicTimerThread(java.lang.String name,
                           int basePriority,
                           RelativeTime interval,
                           AsyncEvent event)

Constructor

Parameters:

name - The name of this thread

basePriority - The base priority of this thread

interval - the delay between cycles of this thread

event - the event to fire on each cycle

Method Detail

body

public void body()
          throws java.lang.InterruptedException

Where all the application work gets done. Analogous to Thread.run(), but that method is used as a wrapper RealTimeThread to initialize, passivate and clean up this RealTimeThread.

Specified by:

body in class RealtimeThread

Throws:

InterruptedException - thrown if a wait() is interrupted

java.lang.InterruptedException - thrown if a wait() is interrupted
