Description

Interface Summary
RateSummaryListener: Receive the state of the rate when its coallesced
StatLog: Component to be notified when a particular event occurs

Class Summary
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.
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.
