public abstract class AbstractPipeline
extends AbstractFlowConstruct
implements Pipeline

Abstract implementation of AbstractFlowConstruct that allows a list of AbstractPipeline.ProcessIfPipelineStartedMessageProcessors that will be used to process messages to be configured. These MessageProcessors are chained together using the DefaultMessageProcessorChainBuilder.

If no message processors are configured then the source message is simply returned.

Method Detail

createPipeline

protected MessageProcessor createPipeline()
                                   throws MuleException

Creates a AbstractPipeline.ProcessIfPipelineStartedMessageProcessor that will process messages from the configured MessageSource .

The default implementation of this methods uses a DefaultMessageProcessorChainBuilder and allows a chain of AbstractPipeline.ProcessIfPipelineStartedMessageProcessors to be configured using the configureMessageProcessors(org.mule.api.processor.MessageProcessorChainBuilder) method but if you wish to use another MessageProcessorBuilder or just a single AbstractPipeline.ProcessIfPipelineStartedMessageProcessor then this method can be overridden and return a single AbstractPipeline.ProcessIfPipelineStartedMessageProcessor instead.
