.. title:: clang-tidy - readability-redundant-access-specifiers

readability-redundant-access-specifiers
=======================================

Finds classes, structs, and unions containing redundant member (field and
method) access specifiers.

Example
-------

.. code-block:: c++

  class Foo {
  public:
    int x;
    int y;
  public:
    int z;
  protected:
    int a;
  public:
    int c;
  }

In the example above, the second ``public`` declaration can be removed without
any changes of behavior.

Options
-------

.. option:: CheckFirstDeclaration

   If set to non-zero, the check will also diagnose if the first access
   specifier declaration is redundant (e.g. ``private`` inside ``class``,
   or ``public`` inside ``struct`` or ``union``).
   Default is `0`.

Example
^^^^^^^

.. code-block:: c++

  struct Bar {
  public:
    int x;
  }

If `CheckFirstDeclaration` option is enabled, a warning about redundant
access specifier will be emitted, because ``public`` is the default member access
for structs.
