To allow deep copying from an existing GenericValue, an
explicit "copy constructor" (with required Allocator param)
and an "CopyFrom" assignment function are added.
Document d; Document::AllocatorType& a = d.GetAllocator();
Value v1("foo");
// Value v2(v1); // not allowed
Value v2(v1,a); // make a copy
RAPIDJSON_ASSERT(v1.IsString()); // v1 untouched
d.SetArray().PushBack(v1,a).PushBack(v2,a);
RAPIDJSON_ASSERT(v1.Empty() && v2.Empty());
v2.CopyFrom(d,a); // copy whole document
RAPIDJSON_ASSERT(d.IsArray() && d.Size()); // d untouched
v1.SetObject().AddMember( "array", v2, a );
d.PushBack(v1,a);
Additionally, the Handler implementation in GenericDocument is made
private again, restricting access to GenericReader and GenericValue.
Rapidjson v0.1 Copyright (c) 2011 Milo Yip (miloyip@gmail.com) http://code.google.com/p/rapidjson/ 19 Nov 2011 1. Introduction Rapidjson is a JSON parser and generator for C++. It was inspired by rapidxml http://rapidxml.sourceforge.net/ Rapidjson is small but complete. It supports both SAX and DOM style API. The SAX parser is only a half thousand lines of code. Rapidjson is fast. Its performance can be comparable to strlen(). It also optionally supports SSE2/SSE4.1 for acceleration. Rapidjson is self-contained. It does not depend on external libraries such as BOOST. It even does not depend on STL. Rapidjson is memory friendly. Each JSON value costs exactly 16/20 bytes for 32/64-bit machines (excluding text string). By default it uses a fast memory allocator, and the parser allocates memory compactly during parsing. For the full features please refer to the user guide. JSON(JavaScript Object Notation) is a light-weight data exchange format. More information about JSON can be obtained at http://json.org/ http://www.ietf.org/rfc/rfc4627.txt 2. Installation Rapidjson is a header-only C++ library. Just copy the rapidjson/include/rapidjson folder to system or project's include path. To build the tests and examples, 1. obtain premake4 http://industriousone.com/premake/download 2. Copy premake4 executable to rapidjson/build 3. Run rapidjson/build/premake.bat on Windows, rapidjson/build/premake on Linux or other platforms 4. On Windows, build the solution at rapidjson/build/vs2008/ or /vs2010/ 5. On other platforms, run GNU make at rapidjson/build/gmake/ (e.g., make -f test.make config=release32, make -f example.make config=debug32) 6. On success, the executable are generated at rapidjson/bin
