Method Detail

add

public void add(double totalValue,
                long eventCount,
                double totalEventTime,
                long period)
Specified by:
add in interface RateSummaryListener
Parameters:
totalValue - sum of all event values in the most recent period
eventCount - how many events occurred
totalEventTime - how long the events were running for
period - how long this period is

createName

static String createName(I2PAppContext ctx,
