All Implemented Interfaces:
AutoCloseable, Runnable, org.apache.camel.Consumer, org.apache.camel.EndpointAware, org.apache.camel.health.HealthCheckAware, org.apache.camel.RouteAware, org.apache.camel.Service, org.apache.camel.ShutdownableService, org.apache.camel.spi.RouteIdAware, org.apache.camel.spi.ShutdownAware, org.apache.camel.spi.ShutdownPrepared, org.apache.camel.StatefulService, org.apache.camel.Suspendable, org.apache.camel.SuspendableService
public class SedaConsumer extends org.apache.camel.support.DefaultConsumer implements Runnable, org.apache.camel.spi.ShutdownAware, org.apache.camel.Suspendable
A Consumer for the SEDA component.

In this implementation there is a little slack period when you suspend/stop the consumer, by which the consumer may pickup a newly arrived messages and process it. That period is up till 1 second.

      protected org.apache.camel.Exchange prepareExchange(org.apache.camel.Exchange exchange)
      Strategy to prepare exchange for being processed by this consumer
      Parameters:
      exchange - the exchange
      Returns:

    • sendToConsumers

      protected void sendToConsumers(org.apache.camel.Exchange exchange) throws Exception
