Used for inclusive filtering of routes from directories. Typical used for specifying to accept routes in XML or YAML files, such as *.yaml,*.xml. Multiple patterns can be specified separated by comma.

setRemoveAllRoutes

public void setRemoveAllRoutes(boolean removeAllRoutes)

When reloading routes should all existing routes be stopped and removed. By default, Camel will stop and remove all existing routes before reloading routes.
