Class MTimer

java.lang.Object
  moss.kernel.MTimer

public class MTimer
extends java.lang.Object

this class is used to provide process timeouts in MOSS. The implementation is somewhat grim, but without a mechanism for absolute time in milli-seconds, the one-thread implementation would suffer incremental-error problems (Java's timeout is "more or less" ...)

Constructor Summary

MTimer()

static void	add_to_timer_queue(MProcess p, long millis) called to add a process to the timer queue
static boolean	del_from_timer_queue(MProcess p) called to remove a process from the timer queue
