Class UniOnItemDelay<T>

  • Type Parameters:
    T - the type of item
    public class UniOnItemDelay<T>
extends java.lang.Object
    Configures the delay applied to the item emission. It allows delaying the item emitted by the previous Uni to its downstream.

        public UniOnItemDelay​(Uni<T> upstream,
                      java.util.concurrent.ScheduledExecutorService executor)
        Creates a new UniOnItemDelay instance.
        Parameters:
        upstream - the upstream uni
        executor - the executor, can be null, if null used the default worker executor.

    • Method Detail

      • onExecutor

        @CheckReturnValue
public UniOnItemDelay<T> onExecutor​(java.util.concurrent.ScheduledExecutorService executor)
        Configures the executor which is used to wait for the delay duration.
        Parameters:
        executor - the executor, must not be null
        Returns:
        this UniOnItemDelay.

      • by

        @CheckReturnValue
public Uni<T> by​(java.time.Duration duration)
        Delays the item emission by a specific duration.
        Parameters:
        duration - the duration of the delay, must not be null, must be strictly positive.
        Returns:
        the produced Uni

      • until

        @CheckReturnValue
public Uni<T> until​(java.util.function.Function<? super T,​Uni<?>> function)
        Delays the item emission until the Uni produced by the given Function emits an item (potentially null)

        When the upstream emits its item, the passed function is called. The returned Uni is subscribed using the configured executor. Once this Uni emits its item, the item emitted by upstream is propagated downstream. If the Uni fails, the failure is propagated instead.

        Parameters:
        function - the function, must not be null
        Returns:
        the produced Uni.
