From 812ed39f9da336310e815c361ab5a9f118657d94 Mon Sep 17 00:00:00 2001 From: Neale Ranns Date: Mon, 16 Oct 2017 04:20:13 -0700 Subject: VPP Object Model (VOM) The VOM is a C++ library for use by clients/agents of VPP for programming state. It uses the binary APIs to do so. Various other common client side functions are also provided. Please see om.hpp for a more detailed description.
