inserts element Inserts element val before iterator pos.
- Parameters
-
[in] | pos | iterator before which the content will be inserted; may be the end() iterator |
[in] | val | element to insert |
- Returns
- iterator pointing to the inserted val.
- 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" |
- Complexity
- Constant 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.begin() + 2, 10);
15 std::cout << *new_pos <<
'\n';
16 std::cout << v <<
'\n';
Output (play with this example online): 10
[1,2,10,3,4]
