Rule ``no_unneeded_final_method``
=================================

A ``final`` class must not have ``final`` methods and ``private`` methods must
not be ``final``.

.. warning:: Using this rule is risky.

   Risky when child class overrides a ``private`` method.

Allowed types: ``bool``

Default value: ``true``

    <?php
    final class Foo
    {

   -    final protected function bar() {}
   -    final private function baz() {}
   +    public function foo1() {}
   +    protected function bar() {}
   +    private function baz() {}
    }

    class Bar
    {
