If Statistic is allowed to run (controlled by Python runtime parameters), then a statistic will be created and returned. If not allowed to run, then a NullStatistic will be returned. 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

statName	Primary name of the statistic. This name must match the defined ElementInfoStatistic in the component, and must also be enabled in the Python input file.
statSubId	An additional sub name for the statistic

Returns: Either a created statistic of desired type or a NullStatistic depending upon runtime settings.

base	Frequency for the clock in SI units
regAll	Should this clock perioud be used as the default time base for all of the links connected to this component

◆ reregisterClock()

Reactivates an existing Clock and Handler.

Returns: time of next time clock handler will fire

◆ setup()

virtual void SST::BaseComponent::setup ( )
