createAggregator
public <T extends PointData,U extends ExemplarData> Aggregator<T,U> createAggregator(InstrumentDescriptor instrumentDescriptor, ExemplarFilter exemplarFilter, MemoryMode memoryMode)
Description copied from interface:AggregatorFactory
Returns a newAggregator
.- Specified by:
createAggregator
in interfaceAggregatorFactory
- Parameters:
instrumentDescriptor
