Introduction

What is rapidjson-devel

RapidJSON is a fast JSON parser and generator for C++. It was inspired by RapidXml. 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 occupies exactly 16/20 bytes for most 32/64-bit machines (excluding text string). By default it uses a fast memory allocator, and the parser allocates memory compactly during parsing. RapidJSON is Unicode friendly. It supports UTF-8, UTF-16, UTF-32 (LE & BE), and their detection, validation and transcoding internally. For example, you can read a UTF-8 file and let RapidJSON transcode the JSON strings into UTF-16 in the DOM. It also supports surrogates and “u0000” (null character). JSON(JavaScript Object Notation) is a light-weight data exchange format. RapidJSON should be in fully compliance with RFC4627/ECMA-404.
