All Implemented Interfaces:

AutoCloseable, org.apache.camel.AsyncProcessor, org.apache.camel.DelegateProcessor, org.apache.camel.Navigate<org.apache.camel.Processor>, org.apache.camel.Processor, org.apache.camel.Service, org.apache.camel.ShutdownableService, org.apache.camel.spi.ShutdownAware, org.apache.camel.spi.ShutdownPrepared, org.apache.camel.StatefulService, org.apache.camel.SuspendableService

Direct Known Subclasses:

Delayer

public abstract class DelayProcessorSupport
extends org.apache.camel.support.processor.DelegateAsyncProcessor
implements org.apache.camel.spi.ShutdownAware

A useful base class for any processor which provides some kind of throttling or delayed processing.

This implementation will block while waiting.
