    • fromPublisher

      @NonNull static <K> @NonNull ReactiveExecutionFlow<K> fromPublisher(@NonNull @NonNull org.reactivestreams.Publisher<K> publisher)
      Creates a new reactive flow from a publisher.
      Type Parameters:
      K - THe flow value type
      Parameters:
      publisher - The publisher
      Returns:
      a new flow

    • fromPublisherEager

      @NonNull static <K> @NonNull io.micronaut.core.execution.ExecutionFlow<K> fromPublisherEager(@NonNull @NonNull org.reactivestreams.Publisher<K> publisher, @NonNull @NonNull io.micronaut.core.propagation.PropagatedContext propagatedContext)
      Creates a new reactive flow from a publisher. This method eagerly subscribes to the publisher, and may return an immediate ExecutionFlow if possible.
      Type Parameters:
      K - The flow value type
      Parameters:
      publisher - The publisher
      propagatedContext - A context to propagate in the reactor context and as a thread-local in the subscribe operation.
      Returns:
      a new flow
      Since:
      4.8.0
