From d1660e980031882627fc1aa42b650c219831dad4 Mon Sep 17 00:00:00 2001 From: Marek Gradzki Date: Wed, 24 Jan 2018 16:35:11 +0100 Subject: jvpp: map VPP API enums to primitive types Adding enum support (VPP-1153) requires JVPP generator refactoring (see: VPP-1154, VPP-1155, VPP-480) As a workaround we just update all the mappings used for VPP API definitions to JAVA and C/JNI translation.
