Class ThreadTimerTask

java.lang.Object
  java.util.TimerTask
      net.sf.basedb.util.timer.ThreadTimerTask

All Implemented Interfaces:

Runnable

public class ThreadTimerTask
extends TimerTask

Class for forcing the execution of a TimerTask in a new thread. Instead of adding the original TimerTask to a Timer an instance of this class is added, which creates a new Thread where the original TimerTask:s run method is executed.

Note that for repeating tasks the use of this class may lead to that the same task is executed again before the previous execution has finished. This may lead to complications if the task is not thread-safe.
