template <typename Json>
Json* get(Json& root, const basic_json_location<Json::char_type>& location);                   (until 0.175.0)

template <typename Json>
std::pair<Json*,bool> get(Json& root, const basic_json_location<Json::char_type>& location);   (since 0.175.0)

Gets a pointer to a JSON value in a JSON document at a specified location.

Parameters

root	Root JSON value
location	A basic_json_location

Return value

Until 0.175.0, returns a pointer to the selected item, or null if not found.

Since 0.175.0, returns a std::pair<Json*,bool>. If the get operation succeeded, the bool component is true, and the Json* component points to the value in the root. If the get operation failed, the bool component is false.

Exceptions
