From 7286b2518ec8e4398b512ce95def9166a7af2e4a Mon Sep 17 00:00:00 2001 From: Deepak S Date: Thu, 13 Jul 2017 21:26:50 -0700 Subject: Adding PROX(Packet pROcessing eXecution engine) VNF to sampleVNF JIRA: SAMPLEVNF-55 PROX is a DPDK-based application implementing Telco use-cases such as a simplified BRAS/BNG, light-weight AFTR... It also allows configuring finer grained network functions like QoS, Routing, load-balancing... (We are moving PROX version v039 to sampleVNF https://01.org/intel-data-plane-performance-demonstrators/prox-overview) Change-Id: Ia3cb02cf0e49ac5596e922c197ff7e010293d033 Signed-off-by: Deepak S --- .../DPPD-PROX/tools/flow_extract/csvfilereader.cpp | 67 ++++++++++++++++++++++ 1 file changed, 67 insertions(+) create mode 100644 VNFs/DPPD-PROX/tools/flow_extract/csvfilereader.cpp (limited to 'VNFs/DPPD-PROX/tools/flow_extract/csvfilereader.cpp') diff --git a/VNFs/DPPD-PROX/tools/flow_extract/csvfilereader.cpp b/VNFs/DPPD-PROX/tools/flow_extract/csvfilereader.cpp new file mode 100644 index 00000000..909fc94d --- /dev/null +++ b/VNFs/DPPD-PROX/tools/flow_extract/csvfilereader.cpp @@ -0,0 +1,67 @@ +/* +// Copyright (c) 2010-2017 Intel Corporation +// +// Licensed under the Apache License, Version 2.0 (the "License"); +// you may not use this file except in compliance with the License. +// You may obtain a copy of the License at +// +// http://www.apache.org/licenses/LICENSE-2.0 +// +// Unless required by applicable law or agreed to in writing, software +// distributed under the License is distributed on an "AS IS" BASIS, +// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +// See the License for the specific language governing permissions and +// limitations under the License. +*/ + +#include +#include +#include +#include + +#include "csvfilereader.hpp" + +int CsvFileReader::open(const string& str) +{ + char *resolved_path = new char[1024]; + + memset(resolved_path, 0, 1024); + realpath(str.c_str(), resolved_path); + file.open(resolved_path); + + delete []resolved_path; + return file.is_open(); +} + +vector CsvFileReader::read() +{ + vector ret; + size_t prev = 0, cur = 0; + string line; + + if (file.eof()) + return vector(); + + std::getline(file, line); + if (line.empty()) + return vector(); + + while (true) { + cur = line.find_first_of(',', prev); + + if (cur != SIZE_MAX) { + ret.push_back(line.substr(prev, cur - prev)); + prev = cur + 1; + } + else { + ret.push_back(line.substr(prev, line.size() - prev)); + break; + } + } + return ret; +} + +void CsvFileReader::close() +{ + file.close(); +} -- cgit 1.2.3-korg
