## 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 **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/SSE4.2 for acceleration.
* RapidJSON is **fast**. Its performance can be comparable to `strlen()`. It also optionally supports SSE2/SSE4.2 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 **self-contained** and **header-only**. 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).

* [Standard ECMA-404: The JSON Data Interchange Format](https://www.ecma-international.org/publications/standards/Ecma-404.htm)
## Highlights in v1.1 (2016-8-25)
* Added [JSON Pointer](doc/pointer.md)
* Added [JSON Schema](doc/schema.md)
* Added [relaxed JSON syntax](doc/dom.md) (comment, trailing comma, NaN/Infinity)
* Iterating array/object with [C++11 Range-based for loop](doc/tutorial.md)
* Reduce memory overhead of each `Value` from 24 bytes to 16 bytes in x86-64 architecture.
For other changes please refer to [change log](CHANGELOG.md).

For the current implementation of deflate(), a windowBits value of 8 (a
window size of 256 bytes) is not supported. As a result, a request for 8
will result in 9 (a 512-byte window). In that case, providing 8 to
inflateInit2() will result in an error when the zlib header with 9 is
checked against the initialization of inflate(). The remedy is to not use 8
with deflateInit2() with this initialization, or at least in that case use 9
with inflateInit2().
windowBits can also be -8..-15 for raw deflate. In this case, -windowBits
determines the window size. deflate() will then generate raw deflate data
with no zlib header or trailer, and will not compute an adler32 check value.
with no zlib header or trailer, and will not compute a check value.
windowBits can also be greater than 15 for optional gzip encoding. Add
16 to windowBits to write a simple gzip header and trailer around the
compressed data instead of a zlib wrapper. The gzip header will have no
file name, no extra data, no comment, no modification time (set to zero), no
header crc, and the operating system will be set to 255 (unknown). If a
gzip stream is being written, strm->adler is a crc32 instead of an adler32.
header crc, and the operating system will be set to the appropriate value,
if the operating system was determined at compile time. If a gzip stream is
being written, strm->adler is a CRC-32 instead of an Adler-32.
For raw deflate or gzip encoding, a request for a 256-byte window is
rejected as invalid, since only the zlib header provides a means of
transmitting the window size to the decompressor.

there was not enough output space to complete the compression of the
