| 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.
