Interface SynchronousMetricStorage

All Superinterfaces:

MetricStorage, WriteableMetricStorage

All Known Implementing Classes:

DefaultSynchronousMetricStorage, EmptyMetricStorage

public interface SynchronousMetricStorage
extends MetricStorage, WriteableMetricStorage

Stores aggregated MetricData for synchronous instruments.

This class is internal and is hence not for public use. Its APIs are unstable and can change at any time.

Method Details

empty

static SynchronousMetricStorage empty()

Returns metric storage which doesn't store or generate any metrics.

create

static <T extends PointData,
U extends ExemplarData>
SynchronousMetricStorage create(RegisteredReader registeredReader,
 RegisteredView registeredView,
 InstrumentDescriptor instrumentDescriptor,
 ExemplarFilter exemplarFilter)

Constructs metric storage for a given synchronous instrument and view.
