    • getActivities

      Iterator<A> getActivities(Layer layer, Instant startTime, Instant endTime, TemporalUnit temporalUnit, ZoneId zoneId)
      Returns an iterator for iterating over all activities found for the given layer and time interval. This method has to return very fast as it gets called many times during rendering of the chart. A slow implementation will have a direct impact on scrolling / rendering performance.
      Parameter:
      layer - the layer for which to return the activities
      startTime - the start time of the time interval for which to return the activities
      endTime - the end time of the time interval for which to return the activities
      temporalUnit - the temporal unit currently displayed in the dateline
      zoneId - the timezone currently displayed in the dateline
      Gibt zurück:
      the activities on the given layer and in the given time interval
