public interface Processor
extends ReactiveProcessor

Processes Event's. Implementations that do not mutate the Event or pass it on to another MessageProcessor should return the MuleEvent they receive. From 4.0 this interface also extends ReactiveProcessor and implementations of this interface can be used in Event stream processing via the default implementation of apply(Publisher) that performs a map function on the stream using the result of the invocation of the blocking process(Event) method. Using this approach simple processor implementations that don't block or perform blocking IO can continue to implement Processor and require no changes.

Since:

3.0

Method Detail

process

Event process(Event event)
       throws org.mule.runtime.api.exception.MuleException

Invokes the MessageProcessor.

Parameters:

event - MuleEvent to be processed

Returns:

optional response MuleEvent

Throws:

org.mule.runtime.api.exception.MuleException

apply

default org.reactivestreams.Publisher<Event> apply(org.reactivestreams.Publisher<Event> publisher)

Applies a Publisher function transforming a stream of Event's.

The default implementation delegates to process(Event) and will:

1. propagate any exception thrown
2. drop events if invocation of process(Event) returns null.

Specified by:

apply in interface Function<org.reactivestreams.Publisher<Event>,org.reactivestreams.Publisher<Event>>

Parameters:

publisher - the event stream to transform

Returns:

the transformed event stream
