< cpp‎ | container‎ | list

(1)
iterator insert( iterator pos, const T& value );
(until C++11)
iterator insert( const_iterator pos, const T& value );
(since C++11)
iterator insert( const_iterator pos, T&& value );
(2) (since C++11)
(3)
void insert( iterator pos, size_type count, const T& value );
(until C++11)
iterator insert( const_iterator pos, size_type count, const T& value );
(since C++11)
(4)
template< class InputIt >
void insert( iterator pos, InputIt first, InputIt last);
(until C++11)
template< class InputIt >
iterator insert( const_iterator pos, InputIt first, InputIt last );
(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 [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 LegacyInputIterator, to avoid ambiguity with the overload (3). (since C++11)
The behavior is undefined if first and last are iterators into *this.
5) inserts elements from initializer list ilist before pos.

No iterators or references are invalidated.

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).


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.

Complexity

1-2) Constant.
3) Linear in count
4) Linear in std::distance(first, last)
5) Linear in ilist.size()

Exceptions

If an exception is thrown, there are no effects (strong exception guarantee).
