Rule ``final_internal_class``

-------------

``annotation_include``
~~~~~~~~~~~~~~~~~~~~~~

.. warning:: This option is deprecated and will be removed on next major version. Use ``include`` to configure PHPDoc annotations tags and attributes.

class (case insensitive).

Allowed types: ``array``

Default value: ``['@internal']``

``annotation_exclude``
~~~~~~~~~~~~~~~~~~~~~~

.. warning:: This option is deprecated and will be removed on next major version. Use ``exclude`` to configure PHPDoc annotations tags and attributes.

Class level attribute or annotation tags that must be omitted to fix the class,
even if all of the white list ones are used as well (case insensitive).

Allowed types: ``array``

Default value: ``['@final', '@Entity', '@ORM\\Entity', '@ORM\\Mapping\\Entity', '@Mapping\\Entity', '@Document', '@ODM\\Document']``

``include``

``consider_absent_docblock_as_internal_class``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Default value: ``false``

Examples
--------

Example #1
~~~~~~~~~~

*Default* configuration.

.. code-block:: diff

   --- Original

   -class Sample
   +final class Sample
    {
    }

.. code-block:: diff

   --- Original
   +++ New
    <?php
    /**
     * @CUSTOM
     */

     * @not-fix
     */
    class B{}
