Class GuavaToAsyncSpanStoreAdapter

java.lang.Object

com.google.common.collect.ForwardingObject

zipkin.spanstore.guava.GuavaToAsyncSpanStoreAdapter

All Implemented Interfaces:

AsyncSpanConsumer, AsyncSpanStore

public abstract class GuavaToAsyncSpanStoreAdapter
extends com.google.common.collect.ForwardingObject
implements AsyncSpanStore, AsyncSpanConsumer

A AsyncSpanStore derived from an GuavaSpanStore. Used to adapt to other composition libraries.

In implementation, this adds the zipkin callback to the future's listeners.
