Method Detail

publish

io.smallrye.mutiny.Uni<Void> publish(String channel,
                                     V message)

Publishes a message to a given channel

Parameters:

channel - the channel

message - the message

Returns:

a Uni producing a null item once the message is sent, a failure otherwise.
