inline |
Inserts elements from initializer list ilist before iterator pos.
- Parameters
-
[in] | pos | iterator before which the content will be inserted; may be the end() iterator |
[in] | ilist | initializer list to insert the values from |
- Exceptions
-
type_error.309 | if called on JSON values other than arrays; example: "cannot use insert() with string" |
invalid_iterator.202 | if pos is not an iterator of *this; example: "iterator does not fit current value" |
- Returns
- iterator pointing to the first element inserted, or pos if
ilist is empty
- Complexity
- Linear in
ilist.size() plus linear in the distance between pos and end of the container.
- Example
- The example shows how
insert() is used.
2 #include <nlohmann/json.hpp>
12 auto new_pos = v.insert(v.end(), {7, 8, 9});
15 std::cout << *new_pos << '\n';
16 std::cout << v << '\n';
