template<typename T >
Statistic<T>* SST::BaseComponent::registerStatistic ( std::string  statName,
std::string  statSubId = "" 
)
inline

Registers a statistic.

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
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 
)

Registers a default time base for the component and optionally sets the the component's links to that timebase.

Useful for components which do not have a clock, but would like a default timebase.

Parameters
baseFrequency for the clock in SI units
regAllShould this clock period be used as the default time base for all of the links connected to this component

Cycle_t SST::BaseComponent::reregisterClock ( TimeConverter freq,
Clock::HandlerBase handler 
)

Reactivates an existing Clock and Handler.

Returns
time of next time clock handler will fire

virtual void SST::BaseComponent::setup ( )
inlinevirtual

Called after all components have been constructed and initialization has completed, but before simulation time has begun.
