Method Detail

sequenceFuture

public static <R> io.vertx.core.Future<List<R>> sequenceFuture(List<io.vertx.core.Future<R>> futures)

Sequence with a list of futures. Transforms a `List[Future[R]]` into a `Future[List[R]]`.

When all futures succeed, the result future completes with the list of each result of elements in futures.

The returned future fails as soon as one of the futures in futures fails. When the list is empty, the returned future will be already completed. Useful for reducing many futures into a single @{link Future}.

Parameters:

futures - a list of futures

Returns:

the transformed future

supply

public <T> io.vertx.core.Future<T> supply(Supplier<T> event)

Supply.

Type Parameters:

T - the generic type

Parameters:

event - the event

Returns:

the future
