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. ^^ insert.cpp
- Output (play with this example online):^^
10
[1,2,10,3,4]
^^ The example code above can be translated withg++ -std=c++11 -Isingle_include doc/examples/insert.cpp -o insert
- Since
- version 1.0.0
