Class DirectVmBlockingProducer

java.lang.Object

org.apache.camel.support.ServiceSupport

org.apache.camel.impl.DefaultProducer

org.apache.camel.impl.DefaultAsyncProducer

org.apache.camel.component.directvm.DirectVmBlockingProducer

All Implemented Interfaces:

AsyncProcessor, EndpointAware, IsSingleton, Processor, Producer, Service, ShutdownableService, StatefulService, SuspendableService

public class DirectVmBlockingProducer
extends DefaultAsyncProducer

The direct producer.

If blocking is enabled (DirectEndpoint#isBlock) then the DirectEndpoint will create an instance of this class instead of DirectProducer. This producers process method will block for the configured duration (DirectEndpoint#getTimeout, default to 30 seconds). After which if a consumer is still unavailable a DirectConsumerNotAvailableException will be thrown.

Implementation note: Concurrent Producers will block for the duration it takes to determine if a consumer is available, but actual consumer execution will happen concurrently.

Method Detail

process

public void process(Exchange exchange)
             throws Exception

Description copied from interface: Processor

Processes the message exchange

Specified by:

process in interface Processor

Overrides:

process in class DefaultAsyncProducer

Parameters:

exchange - the message exchange

Throws:

Exception - if an internal processing error has occurred.

process

public boolean process(Exchange exchange,
                       AsyncCallback callback)

Description copied from interface: AsyncProcessor

Processes the message exchange. Similar to Processor.process(org.apache.camel.Exchange), but the caller supports having the exchange asynchronously processed.

If there was a failure processing then the caused Exception would be set on the Exchange.

Parameters:

exchange - the message exchange

callback - the AsyncCallback will be invoked when the processing of the exchange is completed. If the exchange is completed synchronously, then the callback is also invoked synchronously. The callback should therefore be careful of starting recursive loop.

Returns:

(doneSync) true to continue execute synchronously, false to continue being executed asynchronously

getConsumer

protected DirectVmConsumer getConsumer(Exchange exchange)
                                throws Exception

Throws:

Exception
