Creates a copy of a given JSON value.
- Parameters
-
[in] | other | the JSON value to copy |
- Complexity\n Linear in the size of other.
- Requirements\n 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\n The following code shows an example for the copy
- constructor.
8 json j1 = { "one", "two", 3, 4.5, false};
14 std::cout << j1 << " = " << j2 << '\n';
15 std::cout << std::boolalpha << ( j1 == j2) << '\n';
static basic_json array(std::initializer_list< basic_json > init=std::initializer_list< basic_json >()) explicitly create an array from an initializer list
a class to store JSON values
basic_json<> json default JSON class
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
