From bb5aca8a17448025852c02bd8df690024e966498 Mon Sep 17 00:00:00 2001 From: aramis_acg Date: Fri, 2 Apr 2010 00:17:58 +0000 Subject: [PATCH] Add TinyFormatter, a convenience wrapper around std::stringstream's, intended to replace boost.format. Fix non-standard friend declaration in noboost/shared_ptr. Deprecate boost.format workaround. git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@632 67173fc5-114c-0410-ac8e-9d2fd5bffc1f --- code/BoostWorkaround/boost/format.hpp | 6 + code/BoostWorkaround/boost/shared_ptr.hpp | 4 +- code/TinyFormatter.h | 127 ++++++++++++++++++++++ 3 files changed, 135 insertions(+), 2 deletions(-) create mode 100644 code/TinyFormatter.h diff --git a/code/BoostWorkaround/boost/format.hpp b/code/BoostWorkaround/boost/format.hpp index 6e65d8fc3..5d02899ab 100644 --- a/code/BoostWorkaround/boost/format.hpp +++ b/code/BoostWorkaround/boost/format.hpp @@ -1,5 +1,11 @@ + +/* DEPRECATED placebo workaround, use code/TinyFormatter.h instead. + * + * + * */ + #ifndef AI_BOOST_FORMAT_DUMMY_INCLUDED #define AI_BOOST_FORMAT_DUMMY_INCLUDED diff --git a/code/BoostWorkaround/boost/shared_ptr.hpp b/code/BoostWorkaround/boost/shared_ptr.hpp index 081980739..456c0ef05 100644 --- a/code/BoostWorkaround/boost/shared_ptr.hpp +++ b/code/BoostWorkaround/boost/shared_ptr.hpp @@ -54,7 +54,7 @@ namespace boost { static yes foo(DEST*); static no foo(...); - enum {result = sizeof foo((SRC*)0) == sizeof yes}; + enum {result = (sizeof(foo((SRC*)0)) == sizeof(yes) ? 1 : 0)}; }; template struct enable_if {}; @@ -74,7 +74,7 @@ namespace boost { template class shared_ptr { - friend class shared_ptr; + template friend class shared_ptr; public: // provide a default construtctor diff --git a/code/TinyFormatter.h b/code/TinyFormatter.h new file mode 100644 index 000000000..a79cfbe3b --- /dev/null +++ b/code/TinyFormatter.h @@ -0,0 +1,127 @@ +/* +Open Asset Import Library (ASSIMP) +---------------------------------------------------------------------- + +Copyright (c) 2006-2008, ASSIMP Development Team +All rights reserved. + +Redistribution and use of this software in source and binary forms, +with or without modification, are permitted provided that the +following conditions are met: + +* Redistributions of source code must retain the above + copyright notice, this list of conditions and the + following disclaimer. + +* Redistributions in binary form must reproduce the above + copyright notice, this list of conditions and the + following disclaimer in the documentation and/or other + materials provided with the distribution. + +* Neither the name of the ASSIMP team, nor the names of its + contributors may be used to endorse or promote products + derived from this software without specific prior + written permission of the ASSIMP Development Team. + +THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +"AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +A PARTICULAR PURPOSE ARE DISCLAIMED.
