(since C++11) | |
iterator insert( const_iterator pos, std::initializer_list<T> ilist ); |
(5) | (since C++11) |
Inserts elements at the specified location in the container.
1-2) inserts
value
before pos
3) inserts
count
copies of the value
before pos
4) inserts elements from range
The behavior is undefined if
[first, last)
before pos
.
This overload has the same effect as overload (3) if InputIt is an integral type. |
(until C++11) |
This overload only participates in overload resolution if InputIt qualifies as InputIterator , to avoid ambiguity with the overload (3). |
(since C++11) |
first
and last
are iterators into *this. 5) inserts elements from initializer list
ilist
before pos
.No iterators or references are invalidated.

[edit] Parameters
pos | - | iterator before which the content will be inserted. pos may be the end() iterator
|
value | - | element value to insert |
first, last | - | the range of elements to insert, can't be iterators into container for which insert is called |
ilist | - | initializer list to insert the values from |
Type requirements | ||
-T must meet the requirements of CopyInsertable in order to use overload (1).
| ||
-T must meet the requirements of MoveInsertable in order to use overload (2).
| ||
-T must meet the requirements of CopyAssignable and CopyInsertable in order to use overload (3).
| ||
-T must meet the requirements of EmplaceConstructible in order to use overload (4,5).

[edit] Return value
1-2) Iterator pointing to the inserted
value
3) Iterator pointing to the first element inserted, or
pos
if count==0.4) Iterator pointing to the first element inserted, or
pos
if first==last.5) Iterator pointing to the first element inserted, or
pos
if ilist
is empty.[edit] Complexity
1-2) Constant.
3) Linear in count
4) Linear in std::distance(first, last)
5) Linear in ilist.size()
[edit] Exceptions
If an exception is thrown, there are no effects (strong exception guarantee).
