java.lang.Object
java.util.concurrent.CountDownLatch
brave.test.util.AssertableCallback<V>
- All Implemented Interfaces:
BiConsumer<V,Throwable>
public final class AssertableCallback<V> extends CountDownLatch implements BiConsumer<V,Throwable>
A callback of a single result or error that supports assertions.
This is a bridge to async libraries such as CompletableFuture complete, completeExceptionally.
Implementations will call either onSuccess(V)
or onError(java.lang.Throwable)
, but not both.
