Issue in importing package org.onosproject.p4runtime.api

[drobinkent]

Whenever I try to use "org.onosproject.p4runtime.api" in my onos-app, the api is not found. I have looked into the onos api documentation.
The api is not listed there. But basic onos-pipelines uses those apis.

My question is, is there any way I can use those apis in my application?
Is there any reason behind not exposing those apis to onos applications?
