const std::string &  statName,
const std::string &  statSubId = "" 
)
inline

Registers a statistic.

In either case, the returned value should be used for all future Statistic calls. The type of Statistic and the Collection Rate is set by Python runtime parameters. If no type is defined, then an Accumulator Statistic will be provided by default. If rate set to 0 or not provided, then the statistic will output results only at end of sim (if output is enabled).

Parameters
statNamePrimary name of the statistic. This name must match the defined ElementInfoStatistic in the component, and must also be enabled in the Python input file.
statSubIdAn additional sub name for the statistic
Returns
Either a created statistic of desired type or a NullStatistic depending upon runtime settings.
TimeConverter * SST::BaseComponent::registerTimeBase ( std::string  base,
bool  regAll = true
