The semantics depends on the different types a JSON value can have: In case of primitive types (number, boolean, or string), first must be begin() and last must be end(). In this case, the value is copied. Otherwise, std::out_of_range is thrown. In case of structured types (array, object), the constructor behaves as similar versions for std::vector. In case of a null type, std::domain_error is thrown. Template Parameters InputIT an input iterator type (iterator or const_iterator) Parameters [in] first begin of the range to copy from (included) [in] last end of the range to copy from (excluded) Exceptions std::domain_error if iterators are not compatible; that is, do not belong to the same JSON value; example: "iterators are not compatible" std::out_of_range if iterators are for a primitive type (number, boolean, or string) where an out of range error can be detected easily; example: "iterators out of range" std::bad_alloc if allocation for object, array, or string fails std::domain_error if called with a null value; example: "cannot use construct with iterators from null" Complexity Linear in distance between first and last. Example The example below shows several ways to create JSON values by specifying a subrange with iterators. #include <json.hpp> using namespace nlohmann; int main() { // create JSON values json j_array = {"alpha", "bravo", "charly", "delta", "easy"}; json j_number = 42; json j_object = {{"one", "eins"}, {"two", "zwei"}}; // create copies using iterators json j_array_range(j_array.begin() + 1, j_array.end() - 2); json j_number_range(j_number.begin(), j_number.end()); json j_object_range(j_object.begin(), j_object.find("two")); // serialize the values std::cout << j_array_range << '\n'; std::cout << j_number_range << '\n'; std::cout << j_object_range << '\n'; } Output (play with this example online): ["bravo","charly"] 42 {"one":"eins"} The example code above can be translated with g++ -std=c++11 -Isrc doc/examples/basic_json__InputIt_InputIt.cpp -o basic_json__InputIt_InputIt Since version 1.0.0 Definition at line 1746 of file json.hpp.
