  public <T extends PointData, U extends ExemplarData> Aggregator<T,U> createAggregator(InstrumentDescriptor instrumentDescriptor, ExemplarFilter exemplarFilter, MemoryMode memoryMode)
  
  Description copied from interface: AggregatorFactory
  
  Returns a new Aggregator.
  
  Specified by:
  
  createAggregator in interface AggregatorFactory
  
  Parameters:
  
  instrumentDescriptor - the descriptor of the Instrument that will record measurements.
  
  exemplarFilter - the filter on which measurements should turn into exemplars
  
  memoryMode - The MemoryMode the aggregator will use
