(since C++11) | |
Inserts a new element to the container, using hint as a suggestion where the element should go. The element is constructed in-place, i.e. no copy or move operations are performed. The constructor of the element type (value_type) is called as follows: the first argument is used to construct the key, the rest of the arguments are used to construct the value.
No iterators or references are invalidated.

[edit] Parameters
| hint | - | iterator, used as a suggestion as to where to insert the new element | 
| args | - | arguments to forward to the constructor of the element | 
[edit] Return value
Returns an iterator to the inserted element.
[edit] Complexity
Logarithmic in the size of the container in general, but amortized constant if the new element is inserted just before pos.
