public class DefaultChannel
extends CamelInternalProcessor
implements ModelChannel

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.
