Initialize this scoped guard to record an elapsed time to the metric identified by the specified category and name.
Declared in <balm_stopwatchscopedguard.h>
StopwatchScopedGuard(
char const* category,
char const* name,
MetricsManager* manager = 0);Optionally specify a metrics manager and the timeUnits in which to report elapsed time. If timeUnits is not provided, the elapsed time will be reported in seconds. If manager is 0, use the DefaultMetricsManager instance. If no manager is supplied, and the default instance has not been created, this object will be inactive (i.e., it will not record any values); similarly, if the identified category is disabled, then this object will be inactive. The behavior is undefined unless category and name are null-terminated. Note that timeUnits indicates the scale of the double value reported by this guard, but does not affect the precision of the elapsed time measurement.
| Name | Description |
|---|---|
| category | null-terminated metric category name |

| manager | metrics manager used to provide the collector (optional) |
