Sometimes it is useful to execute some code with a time limit for completion.
public static boolean runTimeLimitedThread(Thread thread, long msecsTimeLimit)
{
long endTimeMsecs = System.currentTimeMillis() + msecsTimeLimit;
if (msecsTimeLimit == 0L || thread == null) return false; // nothing to do
thread.start();
boolean currentThreadNeedsInterrupt = false;
while (System.currentTimeMillis() < endTimeMsecs)
{
if (thread.isAlive())
{
try
{
Thread.sleep(250);
}
catch (InterruptedException e)
{
currentThreadNeedsInterrupt = true;
break;
}
}
else
{
break;
}
}
boolean interrupted = false;
if (thread.isAlive())
{
thread.interrupt();
interrupted = true;
}
if (currentThreadNeedsInterrupt)
{
Thread.currentThread().interrupt();
}
return interrupted;
}
