Overlays

ONOS applications can hook into the ONOS CLI and GUI. When generating your application, you can use overlays to generate the classes needed to give your application access to these services.

CLI Overlay

To allow your application access to the ONOS CLI, overlay the CLI interface like this:

onos-create-app cli org.foo.app foo-app 1.0.0

Now, as before, we need to build and install our application.  Since we installed it once already, we will use the reinstall command to deploy it:

mvn clean install
onos-app localhost reinstall target/foo-app-1.0-SNAPSHOT.oar

Using the ONOS command line, restart the application:

onos> app activate org.foo.app

Using the ONOS command line, we now have access to the 'sample' command, which was defined by our overlay:

onos> sample
Hello World

Happy coding 

Finally your application is loaded and running withing ONOS. Also, the generation process has generated an entire project which can be loaded into your favourite JAVA editor.
