performance-inefficient-algorithm
|
|
=================================
|
|
|
|
|
|
Warns on inefficient use of STL algorithms on associative containers.
|
|
|
|
Associative containers implements some of the algorithms as methods which
|
|
should be preferred to the algorithms in the algorithm header. The methods
|
|
can take advanatage of the order of the elements.

.. code-block:: c++
|
|
|
|
std::set<int> s;
|
|
auto it = std::find(s.begin(), s.end(), 43);
|
|
|
|
// becomes
|
|
|
|
auto it = s.find(43);
|

.. code-block:: c++

std::set<int> s;

auto c = std::count(s.begin(), s.end(), 43);
