Class MappingSubscriber<T,U>

java.lang.Object

software.amazon.awssdk.utils.internal.MappingSubscriber<T,U>

All Implemented Interfaces:

org.reactivestreams.Subscriber<T>

public class MappingSubscriber<T,U>
extends Object
implements org.reactivestreams.Subscriber<T>

Maps a subscriber of one type to another type. If an exception is thrown by the mapping function itself, the error will be propagated to the downstream subscriber as if it had come from the publisher and then the subscription will be implicitly cancelled and no further events from the publisher will be passed along.

Implementation notes: this class should've been outside internal package, but we can't fix it due to backwards compatibility reasons.
