From 93b372e4d8d51a3db161a95a8b1884ce6af117fd Mon Sep 17 00:00:00 2001 From: Gordon Sim Date: Fri, 24 Oct 2008 11:33:40 +0000 Subject: Fix for bug in encoding/decoding of floats and doubles. Added test to verify double/float headers set by c++ are correctly read by python [TODO: add wider range of header types, add bidirectional tests, add tests against other languages] [Also fixed one or two SSL related files missing from distribution list] git-svn-id: https://svn.apache.org/repos/asf/incubator/qpid/trunk/qpid@707604 13f79535-47bb-0310-9956-ffa450edef68 --- cpp/src/qpid/framing/Endian.cpp | 52 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 52 insertions(+) create mode 100644 cpp/src/qpid/framing/Endian.cpp (limited to 'cpp/src/qpid/framing/Endian.cpp') diff --git a/cpp/src/qpid/framing/Endian.cpp b/cpp/src/qpid/framing/Endian.cpp new file mode 100644 index 0000000000..a2d4566e5e --- /dev/null +++ b/cpp/src/qpid/framing/Endian.cpp @@ -0,0 +1,52 @@ +/* + * + * Licensed to the Apache Software Foundation (ASF) under one + * or more contributor license agreements.
