getTransportChannel()
public TransportChannel getTransportChannel()Provides a Transport, which could either be a new instance for every call, or the same instance, depending on the implementation.
If #needsExecutor() is true, then #withExecutor(Executor) needs to be called first to provide an executor.
If #needsHeaders() is true, then #withHeaders(Map) needs to be called first to provide headers.
if #needsEndpoint() is true, then #withEndpoint(String) needs to be called first to provide an endpoint.
