Parameters [in] other the JSON value to copy Complexity Linear in the size of other. Requirements This function helps basic_json satisfying the Container requirements: The complexity is linear. As postcondition, it holds: other == basic_json(other). Exceptions std::bad_alloc if allocation for object, array, or string fails. Example The following code shows an example for the copy constructor. #include <json.hpp> using json = nlohmann::json; int main() { // create a JSON array json j1 = {"one", "two", 3, 4.5, false}; // create a copy json j2(j1); // serialize the JSON array std::cout << j1 << " = " << j2 << '\n'; std::cout << std::boolalpha << (j1 == j2) << '\n'; } Output (play with this example online): ["one","two",3,4.5,false] = ["one","two",3,4.5,false] true The example code above can be translated with g++ -std=c++11 -Isrc doc/examples/basic_json__basic_json.cpp -o basic_json__basic_json Since version 1.0.0 Definition at line 2427 of file json.hpp.
