Class AsyncMetricResolvers

java.lang.Object

com.linkedin.venice.stats.metrics.AsyncMetricResolvers

public final class AsyncMetricResolvers
extends Object

Holder for the four named functional interfaces that wire the two-callback (liveness + value) contract used by AsyncMetricEntityStateOneEnum and AsyncMetricEntityStateTwoEnums. Co-located in a single file because they are only meaningful together.
