Method Detail

publish

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

Description copied from interface: ReactivePubSubCommands

Publishes a message to a given channel

Specified by:

publish in interface ReactivePubSubCommands<V>

Parameters:

channel - the channel

message - the message

Returns:

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

subscribe

public io.smallrye.mutiny.Uni<ReactivePubSubCommands.ReactiveRedisSubscriber> subscribe(String channel,
                                                                                        Consumer<V> onMessage)

Description copied from interface: ReactivePubSubCommands

Subscribes to a given channel.

Specified by:

subscribe in interface ReactivePubSubCommands<V>

Parameters:

channel - the channel

onMessage - the message consumer. Be aware that this callback is invoked for each message sent to the given channel, and is invoked on the I/O thread. So, you must not block. Offload to a separate thread if needed.

Returns:

the subscriber object that lets you unsubscribe

subscribeToPattern

public io.smallrye.mutiny.Uni<ReactivePubSubCommands.ReactiveRedisSubscriber> subscribeToPattern(String pattern,
                                                                                                 Consumer<V> onMessage)

Description copied from interface: ReactivePubSubCommands

Subscribes to a given pattern like chan*l.

Specified by:

subscribeToPattern in interface ReactivePubSubCommands<V>

Parameters:

pattern - the pattern

onMessage - the message consumer. Be aware that this callback is invoked for each message sent to the channels matching the pattern, and is invoked on the I/O thread. So, you must not block. Offload to a separate thread if needed.

Returns:

the subscriber object that lets you unsubscribe

subscribeToPatterns

public io.smallrye.mutiny.Uni<ReactivePubSubCommands.ReactiveRedisSubscriber> subscribeToPatterns(List<String> patterns,
                                                                                                  Consumer<V> onMessage)

Description copied from interface: ReactivePubSubCommands

Subscribes to the given patterns like chan*l.

Specified by:

subscribeToPatterns in interface ReactivePubSubCommands<V>

Parameters:

patterns - the patterns

onMessage - the message consumer. Be aware that this callback is invoked for each message sent to the channels matching the pattern, and is invoked on the I/O thread. So, you must not block. Offload to a separate thread if needed.

Returns:

the subscriber object that lets you unsubscribe

subscribe

public io.smallrye.mutiny.Uni<ReactivePubSubCommands.ReactiveRedisSubscriber> subscribe(List<String> channels,
                                                                                        Consumer<V> onMessage)

Specified by:

subscribe in interface ReactivePubSubCommands<V>

Parameters:

channels - the channels

Returns:

the stream of message

subscribeToPatterns

public io.smallrye.mutiny.Multi<V> subscribeToPatterns(String... patterns)

Description copied from interface: ReactivePubSubCommands

Subscribes to the given patterns. This method returns a Multi emitting an item of type V for each received message. This emission happens on the I/O thread, so you must not block. Use emitOn to offload the processing to another thread.
