iterator emplace( Args&&... args );
(C++11 feature)

Inserts a new element to the container. 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.


[edit] Parameters

args - arguments to forward to the constructor of the element

[edit] Return value
