All Implemented Interfaces:

AutoCloseable, Runnable, org.apache.camel.Consumer, org.apache.camel.EndpointAware, 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.

Constructor Detail

SedaConsumer

public SedaConsumer(SedaEndpoint endpoint,
                    org.apache.camel.Processor processor)

Method Detail

getEndpoint

public SedaEndpoint getEndpoint()

Specified by:

getEndpoint in interface org.apache.camel.EndpointAware

Overrides:

getEndpoint in class org.apache.camel.support.DefaultConsumer

deferShutdown

public boolean deferShutdown(org.apache.camel.ShutdownRunningTask shutdownRunningTask)

Specified by:

deferShutdown in interface org.apache.camel.spi.ShutdownAware

getPendingExchangesSize

public int getPendingExchangesSize()

Specified by:

getPendingExchangesSize in interface org.apache.camel.spi.ShutdownAware

prepareShutdown

public void prepareShutdown(boolean suspendOnly,
                            boolean forced)

Specified by:

prepareShutdown in interface org.apache.camel.spi.ShutdownPrepared

isRunAllowed

public boolean isRunAllowed()

Specified by:

isRunAllowed in interface org.apache.camel.StatefulService

Overrides:

isRunAllowed in class org.apache.camel.support.service.BaseService

run

public void run()

Specified by:

run in interface Runnable

doRun

protected void doRun()

prepareExchange

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:

the exchange to process by this consumer.

sendToConsumers

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

Send the given Exchange to the consumer(s).

If multiple consumers then they will each receive a copy of the Exchange. A multicast processor will send the exchange in parallel to the multiple consumers.

If there is only a single consumer then its dispatched directly to it using same thread.

Parameters:

exchange - the exchange

Throws:

Exception - can be thrown if processing of the exchange failed
