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 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

Returns:

a new Aggregator. Aggregator.drop() indicates no measurements should be recorded.

isCompatibleWithInstrument

public boolean isCompatibleWithInstrument(InstrumentDescriptor instrumentDescriptor)

Description copied from interface: AggregatorFactory

Determine if the Aggregator produced by AggregatorFactory.createAggregator(InstrumentDescriptor, ExemplarFilter, MemoryMode) is compatible with the instrumentDescriptor.

Specified by:

isCompatibleWithInstrument in interface AggregatorFactory

toString

public String toString()

Overrides:
