Example 1 with DefaultMessageProcessorChainBuilder

use of org.mule.runtime.core.privileged.processor.chain.DefaultMessageProcessorChainBuilder in project mule by mulesoft.

the class AbstractPipeline method createPipeline.

/**
 * Creates a {@link Processor} that will process messages from the configured {@link MessageSource} .
 * <p>
 * The default implementation of this methods uses a {@link DefaultMessageProcessorChainBuilder} and allows a chain of
 * {@link Processor}s to be configured using the {@link #configureMessageProcessors(MessageProcessorChainBuilder)} method but if
 * you wish to use another {@link MessageProcessorBuilder} or just a single {@link Processor} then this method can be overridden
 * and return a single {@link Processor} instead.
