Class UniZip

java.lang.Object
io.smallrye.mutiny.groups.UniZip

public class UniZip extends Object
Combines several Uni into a new Uni that will fire an item event when all Uni are resolved successfully aggregating their results (emitted item) into a Tuple, or using a combinator function.

The produced Uni fire a failure if one of Unis produces a failure. This will cause the other Uni to be cancelled, expect if collectFailures() is invoked, which delay firing the failure until all Unis have completed or failed.

      @CheckReturnValue public <T1, T2> UniAndGroup2<T1,T2> unis(Uni<? extends T1> u1, Uni<? extends T2> u2)
      Combines two unis together. Once both Uni have completed successfully, the item can be retrieved as a Tuple2 or computed using a BiFunction.

      The produced Uni fires a failure event if one of the Unis fires a failure. This will cause the other Uni to be cancelled, expect if UniAndGroup2.collectFailures() is invoked which delay the failure event until all Unis have fires an item or failure event. If several unis fire a failure, the propagated failure is a CompositeException wrapping all the collected failures.

      Type Parameters:
      T1 - the type of the item for the first uni
      T2 - the type of the item for the second uni
      Parameters:
      u1 - the first uni, must not be null
      u2 - the second uni, must not be null
      Returns:
      an UniAndGroup2 to configure the combination

      @CheckReturnValue public <T1, T2, T3> UniAndGroup3<T1,T2,T3> unis(Uni<? extends T1> u1, Uni<? extends T2> u2, Uni<? extends T3> u3)
      Combines the three unis together. Once all Uni have completed successfully, the item can be retrieved as a Tuple3 or computed using a Functions.Function3.

      The produced Uni fires a failure event if one of the Unis fires a failure. This will cause the other Uni to be cancelled, expect if UniAndGroup3.collectFailures() is invoked which delay the failure event until all Unis have fires an item or failure event. If several unis fire a failure, the propagated failure is a CompositeException wrapping all the collected failures.

      Type Parameters:
      T1 - the type of the item for the first uni
      T2 - the type of the item for the second uni
      T3 - the type of the item for the third uni
      Parameters:
      u1 - the first uni to be combined, must not be null
      u2 - the second uni to be combined, must not be null
      u3 - the third uni to be combined, must not be null
      Returns:

      Combines four unis together. Once all Uni have completed successfully, the item can be retrieved as a Tuple4 or computed using a Functions.Function4.

      The produced Uni fires a failure event if one of the Unis fires a failure. This will cause the other Uni to be cancelled, expect if UniAndGroup4.collectFailures() is invoked which delay the failure event until all Unis have fires an item or failure event.

      Type Parameters:
      T1 - the type of the item for the first uni
      T2 - the type of the item for the second uni
      T3 - the type of the item for the third uni
