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.
