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.

initChannel

public void initChannel(org.apache.camel.spi.RouteContext routeContext,
                        org.apache.camel.NamedNode definition,
                        org.apache.camel.NamedNode childDefinition,
                        List<org.apache.camel.spi.InterceptStrategy> interceptors,

                        boolean routeScoped)
                 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:

routeContext - 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
