/**\mainpage\section _intro Introduction<a HREF="http://www.json.org/">JSON (JavaScript Object Notation)</a>is a lightweight data-interchange format.Here is an example of JSON data:\verbatim{"encoding" : "UTF-8","plug-ins" : ["python","c++","ruby"],"indent" : { "length" : 3, "use_space": true }}\endverbatim<b>JsonCpp</b> supports comments as <i>meta-data</i>:\code// Configuration options{// Default encoding for text"encoding" : "UTF-8",// Plug-ins loaded at start-up"plug-ins" : ["python","c++", // trailing comment"ruby"],// Tab indent size// (multi-line comment)"indent" : { /*embedded comment*/ "length" : 3, "use_space": true }}\endcode\section _features Features- read and write JSON document- attach C++ style comments to element during parsing- rewrite JSON document preserving original commentsNotes: Comments used to be supported in JSON but were removed forportability (C like comments are not supported in Python). Sincecomments are useful in configuration/input file, this feature waspreserved.\section _example Code example\codeJson::Value root; // 'root' will contain the root value after parsing.std::cin >> root;// You can also read into a particular sub-value.std::cin >> root["subtree"];// Get the value of the member of root named 'encoding',// and return 'UTF-8' if there is no such member.std::string encoding = root.get("encoding", "UTF-8" ).asString();// Get the value of the member of root named 'plug-ins'; return a 'null' value if// there is no such member.const Json::Value plugins = root["plug-ins"];// Iterate over the sequence elements.for ( int index = 0; index < plugins.size(); ++index )loadPlugIn( plugins[index].asString() );// Try other datatypes. Some are auto-convertible to others.foo::setIndentLength( root["indent"].get("length", 3).asInt() );foo::setIndentUseSpace( root["indent"].get("use_space", true).asBool() );// Since Json::Value has an implicit constructor for all value types, it is not// necessary to explicitly construct the Json::Value object.root["encoding"] = foo::getCurrentEncoding();root["indent"]["length"] = foo::getCurrentIndentLength();root["indent"]["use_space"] = foo::getCurrentIndentUseSpace();// If you like the defaults, you can insert directly into a stream.std::cout << root;// Of course, you can write to `std::ostringstream` if you prefer.// If desired, remember to add a linefeed and flush.std::cout << std::endl;\endcode\section _advanced Advanced usageConfigure *builders* to create *readers* and *writers*. Forconfiguration, we use our own `Json::Value` (rather thanstandard setters/getters) so that we can addfeatures without losing binary-compatibility.\code// For convenience, use `writeString()` with a specialized builder.Json::StreamWriterBuilder wbuilder;wbuilder["indentation"] = "\t";std::string document = Json::writeString(wbuilder, root);// Here, using a specialized Builder, we discard comments and// record errors as we parse.Json::CharReaderBuilder rbuilder;rbuilder["collectComments"] = false;std::string errs;bool ok = Json::parseFromStream(rbuilder, std::cin, &root, &errs);\endcodeYes, compile-time configuration-checking would be helpful,but `Json::Value` lets youwrite and read the builder configuration, which is better! In other words,you can configure your JSON parser using JSON.CharReaders and StreamWriters are not thread-safe, but they are re-usable.\codeJson::CharReaderBuilder rbuilder;cfg >> rbuilder.settings_;std::unique_ptr<Json::CharReader> const reader(rbuilder.newCharReader());reader->parse(start, stop, &value1, &errs);// ...reader->parse(start, stop, &value2, &errs);// etc.\endcode\section _pbuild Build instructionsThe build instructions are located in the file<a HREF="https://github.com/open-source-parsers/jsoncpp/blob/master/README.md">README.md</a> in the top-directory of the project.The latest version of the source is available in the project's GitHub repository:<a HREF="https://github.com/open-source-parsers/jsoncpp/">jsoncpp</a>\section _news What's New?The description of latest changes can be found in<a HREF="https://github.com/open-source-parsers/jsoncpp/wiki/NEWS">the NEWS wiki</a>.\section _rlinks Related links- <a HREF="http://www.json.org/">JSON</a> Specification and alternate language implementations.- <a HREF="http://www.yaml.org/">YAML</a> A data format designed for human readability.- <a HREF="http://www.cl.cam.ac.uk/~mgk25/unicode.html">UTF-8 and Unicode FAQ</a>.\section _plinks Old project links- <a href="https://sourceforge.net/projects/jsoncpp/">https://sourceforge.net/projects/jsoncpp/</a>- <a href="http://jsoncpp.sourceforge.net">http://jsoncpp.sourceforge.net</a>- <a href="http://sourceforge.net/projects/jsoncpp/files/">http://sourceforge.net/projects/jsoncpp/files/</a>- <a href="http://jsoncpp.svn.sourceforge.net/svnroot/jsoncpp/trunk/">http://jsoncpp.svn.sourceforge.net/svnroot/jsoncpp/trunk/</a>- <a href="http://jsoncpp.sourceforge.net/old.html">http://jsoncpp.sourceforge.net/old.html</a>\section _license LicenseSee file <a href="https://github.com/open-source-parsers/jsoncpp/blob/master/LICENSE"><code>LICENSE</code></a> in the top-directory of the project.Basically JsonCpp is licensed under MIT license, or public domain if desiredand recognized in your jurisdiction.\author Baptiste Lepilleur <blep@users.sourceforge.net> (originator)\author Christopher Dunn <cdunn2001@gmail.com> (primary maintainer)\version \include versionWe make strong guarantees about binary-compatibility, consistent with<a href="http://apr.apache.org/versioning.html">the Apache versioning scheme</a>.\sa version.h*/
