JsonParser for C++

This project is a full-fledged JSON parser that is capable of parsing any .json file following the RFC4627 standard into an easily traversable C++ data structure.

How to use

1. Parse a JSON file.

auto parser = new Json::Parser();
auto json = parser.parse("path_to_json");

2. Traverse the returned JSON structure

auto node = json->at("users")->at(0)->at("age");

3. Convert node to value

int age = node->getAs<int>();

4. Iterate through a list or an object

for (auto user : json->at("users"))
{
	std::string userName = user->at("name")->getAs<std::string>();
}

Notes

• The getAs<T>() method only accepts types that can be stored in a JSON node, such types are: bool, int, double, std::string, std::nullptr_t, Json::List and Json::Object.
• Json::List and Json::Object hide an std::vector and an std::map of Json::Node shared pointers respectively.
• Trying to perform an unsupported conversion using the getAs<T>() function (i.e the user tries to convert a string node to int) throws an exception.
• Trying to use the at(int) function on a non-list node, as well as trying to use the at(std::string) function on a non-object node throws an exception.
• The parser will throw an exception if the JSON object found in the provided .json file contains serious formatting errors.
