std::set const iterators
|
||||
------------------------
|
||||
|
||||
The ``find()`` member function of a ``const`` ``std::set`` instance may not be
|
||||
used in a comparison with the iterator returned by ``end()``:
|
||||
|
||||
.. code-block:: c++
|
||||
|
||||
const std::set<std::string>& someSet = getSet();
|
||||
if (someSet.find("needle") == someSet.end()) // Wrong
|
||||
{
|
||||
// ...
|
||||
}
|
||||
|
||||
The return value of ``find()`` must be assigned to an intermediate
|
||||
``const_iterator`` for comparison:
|
||||
|
||||
.. code-block:: c++
|
||||
|
||||
const std::set<std::string>& someSet;
|
||||
const std::set<std::string>::const_iterator i = someSet.find("needle");
|
||||
if (i != propSet.end()) // Ok
|
||||
{
|
||||
// ...
|
||||
}
