Type Parameters:

V - Value type.

All Superinterfaces:

CompletionStage<V>, Future<V>

All Known Implementing Classes:

AsyncCommand, PipelinedRedisFuture, TransactionalCommand

public interface RedisFuture<V>
extends CompletionStage<V>, Future<V>

A RedisFuture represents the result of an asynchronous computation, extending CompletionStage. The execution of the notification happens either on finish of the future execution or, if the future is completed already, immediately.
