If one doesn't use Threads or Timers , they wouldn't need synch, as all input/output is handled by a single thread. However, if one introduces TimerTasks, synchronization would be mandatory.
There are two ways to synch the code in J2ME:
Display.callSerially(Runnable r)
so that all external events would be synched with the Event Thread. The question is: which way is better or, at least, more widely used? And secondly: if the second way is the preferred one, is the following implementation, reasonable?
class MyTimerTask extends TimerTask {
Display display;
RunnableObject r {
public void run() {
...
}
}
...
public void run() {
display.callSerially(r);
}
}
Thanks!
I prefer the second one, it is more clear to me. I can't see anything wrong with your implementation, I think you can use it safely.
