All Implemented Interfaces:

AutoCloseable, org.apache.camel.AsyncProcessor, org.apache.camel.Channel, 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.StatefulService, org.apache.camel.SuspendableService

public class DefaultChannel
extends CamelInternalProcessor
implements org.apache.camel.Channel

DefaultChannel is the default Channel.

The current implementation is just a composite containing the interceptors and error handler that beforehand was added to the route graph directly.
With this Channel we can in the future implement better strategies for routing the Exchange in the route graph, as we have a Channel between each and every node in the graph.

Specified by:

getRoute in interface org.apache.camel.Channel

doStart

protected void doStart()
                throws Exception

Overrides:

doStart in class org.apache.camel.support.processor.DelegateAsyncProcessor

Throws:

Exception

doStop

protected void doStop()
               throws Exception

Overrides:

doStop in class org.apache.camel.support.processor.DelegateAsyncProcessor

Throws:

Exception

doShutdown

protected void doShutdown()
                   throws Exception

Overrides:

Throws:

Exception

initChannel

public void initChannel(org.apache.camel.Route route,
                        org.apache.camel.NamedNode definition,
                        org.apache.camel.NamedNode childDefinition,
                        List<org.apache.camel.spi.InterceptStrategy> interceptors,
                        org.apache.camel.Processor nextProcessor,

                        boolean first)
                 throws Exception

Initializes the channel. If the initialized output definition contained outputs (children) then the childDefinition will be set so we can leverage fine grained tracing

Parameters:

route - the route context

definition - the route definition the Channel represents

childDefinition - the child definition

Throws:

Exception - is thrown if some error occurred

postInitChannel

public void postInitChannel()
                     throws Exception

Post initializes the channel.

Throws:

Exception - is thrown if some error occurred

toString

public String toString()

Overrides:

toString in class CamelInternalProcessor
