Method Detail

toUni

public static <T> io.smallrye.mutiny.Uni<T> toUni(Consumer<io.vertx.core.Handler<io.vertx.core.AsyncResult<T>>> handler)

Returns a Uni that, when subscribed, uses the provided handler to adapt a callback-based asynchronous method.

For example:

 {
     @code
     io.vertx.core.Vertx vertx = Vertx.vertx();
     Uni blockingMethodResult = UniHelper
             .toMaybe(handler -> vertx. executeBlocking(fut -> fut.complete(invokeBlocking()), handler));
 }
 

This is useful when using Mutiny without the Vert.x Mutiny API or your own asynchronous methods.

Parameters:

handler - the code executed when the returned Uni is subscribed.

Returns:

the uni

toSubscriber

public static <T> io.smallrye.mutiny.subscription.UniSubscriber<T> toSubscriber(io.vertx.core.Handler<io.vertx.core.AsyncResult<T>> handler)

Adapts an Vert.x Handler<AsyncResult<T>> to an UniSubscriber.

The returned observer can be subscribed to an Uni.subscribe().

Parameters:

handler - the handler to adapt

Returns:

the observer
