TimerThread
public class TimerThread extends Thread (Code)
Simple timer class used to implement login and query timeouts.

This thread runs as a Daemon thread to ensure that the java VM will exit correctly when normal execution is complete.

It provides both a singleton implementation and a default constructor for the case when more than one timer thread is desired.

     Construct a new TimerThread instance.

Method Summary
public  booleancancelTimer(Object handle)
     Remove a redundant timer before it expires.
public static synchronized  TimerThreadgetInstance()
     Singleton getter.
public  booleanhasExpired(Object handle)
     Check whether a timer has expired.

Constructor Detail
TimerThread
public TimerThread()(Code)
Construct a new TimerThread instance.




Method Detail
cancelTimer
public boolean cancelTimer(Object handle)(Code)
Remove a redundant timer before it expires.
Parameters:
  handle - handle to the request to be removed from the queue (aTimerRequest instance) true if timer had not expired



getInstance
public static synchronized TimerThread getInstance()(Code)
Singleton getter.



hasExpired
public boolean hasExpired(Object handle)(Code)
Check whether a timer has expired.
Parameters:
  handle - handle to the request to be checked for expiry (aTimerRequest instance) true if timer has expired



run
public void run()(Code)
Execute the TimerThread main loop.



setTimer
public Object setTimer(int timeout, TimerListener l)(Code)
Add a timer request to the queue.

The queue is ordered by time so that the head of the list is always the first timer to expire.
Parameters:
  timeout - the interval in milliseconds after which the timer willexpire
Parameters:
  l - TimerListener to be notified on timeout a handle to the timer request, that can later be used withcancelTimer
