◆ getCounters()

Integer Arcane::LinuxPerfPerformanceCounterService::getCounters	(	Int64ArrayView	counters,
		bool	do_substract )

inlineoverridevirtual

Retrieves the current values of the counters.

This method must only be called if isStarted() is true.

If do_substract is false, fills counters with the current values of the counters. If do_substract is true, fills counters with the difference between the current values and those in counters during the call.

Int64ArrayView counters = ...;
IPerformanceCounterService* p = ...;
p->getCounters(counters,false);
... // Operation.
p->getCounters(counters,true);
info() << "Nb cycle=" << counters[0].
