Classes in io.opentelemetry.sdk.metrics.internal.exemplar that implement ExemplarReservoir

Modifier and Type	Class	Description
(package private) class	FilteredExemplarReservoir<T extends ExemplarData>	A reservoir that has a pre-filter on measurements.
(package private) class	FixedSizeExemplarReservoir<T extends ExemplarData>	Base for fixed-size reservoir sampling of Exemplars.
(package private) class	HistogramExemplarReservoir	A reservoir that records the latest measurement for each histogram bucket.
