Inserts element(s) into the container, if the container doesn't already contain an element with an equivalent key.
-
(1-2) Inserts value. Inserts value. If the container has elements with equivalent key, inserts at the upper bound of that range.
-
(3-4)
- od C++11
- do C++11
Inserts value in the position as close as possible, just prior, to hint.Inserts value in the position as close as possible to hint. -
(5) Inserts elements from range [ first, last ).
-
(6) Inserts elements from initializer list
ilist
. -
(7) If
nh
is an empty node handle, does nothing. Otherwise, inserts the element owned bynh
into the container, if the container doesn't already contain an element with a key equivalent tonh.key()
. The behavior is undefined ifnh
is not empty andget_allocator() != nh.get_allocator()
. -
(8) If
nh
is an empty node handle, does nothing and returns the end iterator. Otherwise, inserts the element owned bynh
into the container, if the container doesn't already contain an element with a key equivalent ton.key()
, and returns the iterator pointing to the element with key equivalent tonh.key()
(regardless of whether the insert succeeded or failed). If the insertion succeeds,nh
is moved from, otherwise it retains ownership of the element. The element is inserted as close as possible to the position just prior to hint. The behavior is undefined ifnh
is not empty andget_allocator() != nh.get_allocator()
.

If the insertion is successful, pointers and references to the element obtained while it is held in the node handle are invalidated, and pointers and references obtained to that element before it was extracted become valid.
Parameters
hint
- od C++11
- do C++11
iterator to the position before which the new element will be insertediterator, used as a suggestion as to where to start the searchvalue
- element value to insertfirst
,last
- the range of elements to insertilist
- initializer list to insert the values fromnh
- a compatible node handle
Type requirements
- (5) -
InputIt
must meet the requirements ofLegacyInputIterator
.
Return value
- (1-4) Returns an iterator to the inserted element.
- (5-6) (none)
- (7-8) End iterator if
nh
is empty, iterator pointing to the inserted element otherwise.
Complexity
- (1-2) Logarithmic in the size of the container - O(log size()).
- (3-4)
- od C++11
- do C++11
Amortized constant if the insertion happens in the position just before thehint
- O(1).
Logarithmic in the size of the container otherwise - O(log size()).Amortized constant if the insertion happens in the position just after thehint
- O(1).
Logarithmic in the size of the container otherwise - O(log size()). - (5-6) O(N * log(size() + N)), where N is the number of elements to insert.
- (7) Logarithmic in the size of the container - O(log size()).
- (8)
Amortized constant if the insertion happens in the position just before thehint
- O(1).
Logarithmic in the size of the container otherwise - O(log size()).
Exceptions
- (1-4) If an exception is thrown by any operation, the insertion has no effect.
