Class Summary

Class	Description
BufferedStatLog	Note - if no filter is defined in stat.logFilters at startup, this class will not be instantiated - see StatManager.
Frequency	Manage the calculation of a moving average event frequency over a certain period.
FrequencyStat	coordinate an event frequency over various periods
PersistenceHelper	Output rate data.
Rate	Simple rate calculator for periodically sampled data points - determining an average value over a period, the number of events in that period, the maximum number of events (using the interval between events), and lifetime data.
RateAverages	Storage space for computations of various averages.
RateStat	coordinate a moving rate over various periods
StatManager	Coordinate the management of various frequencies and rates within I2P components, both allowing central update and retrieval, as well as distributed creation and use.
