Using seTimer

• We timed the two previous versions of the counting code using the following:

seTimer timer;

timer.start();

countLSRXForm(transm.getRoot());

printf("Count = %d LSR XForm = %d\n", _count, _lsrxform);

printf(" Time = %s\n", timer.toStr());

_count = _lsrxform = 0;

timer.start();

recurse(transm.getRoot());

printf("Count = %d LSR XForm = %d\n", _count, _lsrxform);

printf(" Time = %s\n", timer.toStr());

• No need to stop timer after printing. To reuse just call start() again.

• You can store elapsed times at several places by calling elapsed().

• Note the timer returns wall time currently. CPU (application) time is not implemented.
