.. title:: clang-tidy - modernize-use-override
modernize-use-override
======================
Adds ``override`` (introduced in C++11) to overridden virtual functions and
removes ``virtual`` from those functions as it is not required.
``virtual`` on non base class implementations was used to help indiciate to the
user that a function was virtual. C++ compilers did not use the presence of
this to signify an overriden function.
In C++ 11 ``override`` and ``final`` keywords were introduced to allow
overridden functions to be marked appropriately. Their presence allows
compilers to verify that an overridden function correctly overrides a base
class implementation.
This can be useful as compilers can generate a compile time error when:
- The base class implementation function signature changes.
- The user has not created the override with the correct signature.
Options
-------
.. option:: IgnoreDestructors
If set to non-zero, this check will not diagnose destructors. Default is `0`.
.. option:: OverrideSpelling
Specifies a macro to use instead of ``override``. This is useful when
maintaining source code that also needs to compile with a pre-C++11
compiler.
.. option:: FinalSpelling
Specifies a macro to use instead of ``final``. This is useful when
maintaining source code that also needs to compile with a pre-C++11
compiler.
.. note::
For more information on the use of ``override`` see https://en.cppreference.com/w/cpp/language/override
