Rapidjson is a C + + fast JSON parser and generator that uses the Sax/dom style API design.

Example code:

Rapidjson/example/simpledom/simpledom.cpp '#include "Rapidjson/document.h"#include "Rapidjson/writer.h"#include "Rapidjson/stringbuffer.h"#include <iostream>Usingnamespace Rapidjson;int main () { 1. Parse a JSON string into DOM. Constchar* JSON ="{\" project\ ": \" rapidjson\ ", \" Stars\ ": 10}"; Document D;  D.parse (JSON);  //2. Modify it by Dom. value& s = D[ "stars"]; S.setint (s . GetInt () + 1);  //3. Stringify the Dom StringBuffer buffer; writer<stringbuffer> writer (buffer);  D.accept (writer);  //Output {"Project": "Rapidjson", "Stars": 11} Span class= "built_in" >std::cout << buffer. GetString () << std::endl; return 0;}

Main Features:

• Small, full-featured, sax and DOM-style APIs, only a SAX parser with only hundred lines of code

• Fast

• No reliance on other third-party libraries

• Compact. Each JSON value is a bytes for a or 64-bit machines respectively (excluding text string storage). With the custom memory allocator, parser allocates memory compactly during parsing.

• Fully compatible with RFC4627, support UTF-8, UTF-16 and UTF-32.

• Support both In-situ parsing (directly decode strings into the source JSON text) and non-destructive parsing (decode Strin GS into new buffers).

• Parse number to int/unsigned/int64_t/uint64_t/double depending on input

• Supports custom memory allocations. Also, the default memory pool allocator can Also is supplied with a user buffer (such as a buffer allocated on user ' s heap or programme stack) to minimize allocation.
