Statistics::Statistic<T>* SST::BaseComponent::registerStatistic ( SST::Params params,
const std::string &  statName,
const std::string &  statSubId = "",
bool  inserting = false 
)
inlineprotected

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 ( const std::string &  base,

protected

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

void SST::BaseComponent::requireLibrary ( const std::string &  name)
protected

Signifies that a library is required for this simulation.

Causes the Factory to verify that the required library is loaded.

NOTE: This function should rarely be required, as most dependencies are automatically detected in the simulator core. However, if the component uses an event from another library that is not wholly defined in a header file, this call may be required to ensure that all the code from the event is loaded. Similarly, if you use a class from another library that does not have ELI information, this call may also be required to make sure all dependencies are loaded.

Parameters
nameName of library this BaseComponent depends on

Convenience function for testing for and reporting fatal conditions.
