TemporalCounter¶

Overview¶

Used by EngagementMetrics to keep track of the seconds in which activity occurs. For example, with a binSize of 1000, calling onEvent with three values within the range of 1000 will result in a single "count" because they were all in a bin. See unit tests for more examples.
