From f761dc72f426444d56dbe9ed12b2823b08a68aa9 Mon Sep 17 00:00:00 2001 From: Krishty Date: Fri, 16 Apr 2021 23:43:56 +0200 Subject: [PATCH 01/12] style fix - initializing and assigning empty std::string properly MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit std::string s(""); s = ""; calls the copy constructor, which in turn calls strlen(), … assigning a default-constructed string generates fewer instructions and is therefore preferred. With C++11 uniform initialization, you’d simply write s = { } instead. --- code/AssetLib/3DS/3DSConverter.cpp | 2 +- code/AssetLib/3DS/3DSLoader.cpp | 2 +- code/AssetLib/3MF/D3MFOpcPackage.cpp | 2 +- code/AssetLib/AC/ACLoader.h | 4 ++-- code/AssetLib/ASE/ASEParser.cpp | 2 +- code/AssetLib/Collada/ColladaLoader.cpp | 2 +- code/AssetLib/FBX/FBXMeshGeometry.cpp | 2 +- code/AssetLib/FBX/FBXParser.cpp | 8 ++++---- code/AssetLib/FBX/FBXProperties.cpp | 2 +- code/AssetLib/IFC/IFCLoader.cpp | 4 ++-- code/AssetLib/Irr/IRRLoader.cpp | 2 +- code/AssetLib/Irr/IRRMeshLoader.cpp | 2 +- code/AssetLib/LWO/LWOFileData.h | 2 +- code/AssetLib/LWS/LWSLoader.h | 2 +- .../MDL/HalfLife/UniqueNameGenerator.cpp | 2 +- code/AssetLib/MMD/MMDImporter.cpp | 2 +- code/AssetLib/MMD/MMDPmxParser.cpp | 2 +- code/AssetLib/OpenGEX/OpenGEXImporter.cpp | 2 +- code/AssetLib/OpenGEX/OpenGEXImporter.h | 2 +- code/AssetLib/Q3BSP/Q3BSPFileData.h | 2 +- code/AssetLib/Q3BSP/Q3BSPFileImporter.cpp | 16 ++++++++-------- code/AssetLib/X/XFileHelper.h | 2 +- code/AssetLib/XGL/XGLLoader.cpp | 2 +- code/AssetLib/glTF/glTFAsset.h | 2 +- code/AssetLib/glTF2/glTF2Asset.h | 2 +- code/Common/BaseImporter.cpp | 2 +- code/Common/FileSystemFilter.h | 2 +- code/Common/Importer.cpp | 6 +++--- code/Common/scene.cpp | 2 +- code/PostProcessing/RemoveRedundantMaterials.h | 2 +- include/assimp/DefaultIOStream.h | 2 +- include/assimp/IOSystem.hpp | 2 +- include/assimp/Importer.hpp | 2 +- include/assimp/XmlParser.h | 2 +- 34 files changed, 48 insertions(+), 48 deletions(-) diff --git a/code/AssetLib/3DS/3DSConverter.cpp b/code/AssetLib/3DS/3DSConverter.cpp index 12ac7e69e..c977867c0 100644 --- a/code/AssetLib/3DS/3DSConverter.cpp +++ b/code/AssetLib/3DS/3DSConverter.cpp @@ -212,7 +212,7 @@ void Discreet3DSImporter::ConvertMaterial(D3DS::Material &oldMat, mat.AddProperty(&tex, AI_MATKEY_GLOBAL_BACKGROUND_IMAGE); // Be sure this is only done for the first material - mBackgroundImage = std::string(""); + mBackgroundImage = std::string(); } // At first add the base ambient color of the scene to the material diff --git a/code/AssetLib/3DS/3DSLoader.cpp b/code/AssetLib/3DS/3DSLoader.cpp index 0a64f6870..10aa10786 100644 --- a/code/AssetLib/3DS/3DSLoader.cpp +++ b/code/AssetLib/3DS/3DSLoader.cpp @@ -164,7 +164,7 @@ void Discreet3DSImporter::InternReadFile(const std::string &pFile, mRootNode->mHierarchyIndex = -1; mRootNode->mParent = nullptr; mMasterScale = 1.0f; - mBackgroundImage = ""; + mBackgroundImage = std::string(); bHasBG = false; bIsPrj = false; diff --git a/code/AssetLib/3MF/D3MFOpcPackage.cpp b/code/AssetLib/3MF/D3MFOpcPackage.cpp index 514e3c2f3..ec0861fc1 100644 --- a/code/AssetLib/3MF/D3MFOpcPackage.cpp +++ b/code/AssetLib/3MF/D3MFOpcPackage.cpp @@ -188,7 +188,7 @@ bool D3MFOpcPackage::validate() { std::string D3MFOpcPackage::ReadPackageRootRelationship(IOStream *stream) { XmlParser xmlParser; if (!xmlParser.parse(stream)) { - return ""; + return std::string(); } OpcPackageRelationshipReader reader(xmlParser); diff --git a/code/AssetLib/AC/ACLoader.h b/code/AssetLib/AC/ACLoader.h index 77de16b8b..5ae2e80bb 100644 --- a/code/AssetLib/AC/ACLoader.h +++ b/code/AssetLib/AC/ACLoader.h @@ -123,9 +123,9 @@ public: struct Object { Object() : type(World), - name(""), + name(), children(), - texture(""), + texture(), texRepeat(1.f, 1.f), texOffset(0.0f, 0.0f), rotation(), diff --git a/code/AssetLib/ASE/ASEParser.cpp b/code/AssetLib/ASE/ASEParser.cpp index 21ec26593..530766730 100644 --- a/code/AssetLib/ASE/ASEParser.cpp +++ b/code/AssetLib/ASE/ASEParser.cpp @@ -685,7 +685,7 @@ void Parser::ParseLV3MapBlock(Texture &map) { // Files with 'None' as map name are produced by // an Maja to ASE exporter which name I forgot ..
