Detailed Description

template<typename NumberBase>
class SST::Statistics::AccumulatorStatistic< NumberBase >

Allows the online gathering of statistical information about a single quantity.

The basic statistics are captured online removing the need to keep a copy of the values of interest.

Template Parameters
NumberBaseA template for the basic numerical type of values
