The body of each structure MUST be enclosed by braces. Braces should be properly
placed. Body of braces should be properly indented.

Warning
-------

This rule is deprecated and will be removed in the next major version
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

You should use ``single_space_around_construct``, ``control_structure_braces``,
``control_structure_continuation_position``, ``declare_parentheses``,
``no_multiple_statements_per_line``, ``braces_position``,
``statement_indentation`` and ``no_extra_blank_lines`` instead.

Configuration
-------------

``allow_single_line_anonymous_class_with_empty_body``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Whether single line anonymous class with empty body notation should be allowed.

Allowed types: ``bool``

Default value: ``false``

``allow_single_line_closure``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Whether single line lambda notation should be allowed.

Allowed types: ``bool``

Default value: ``false``

``position_after_anonymous_constructs``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Whether the opening brace should be placed on "next" or "same" line after
anonymous constructs (anonymous classes and lambda functions).

Allowed values: ``'next'`` and ``'same'``

Default value: ``'same'``

``position_after_control_structures``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Whether the opening brace should be placed on "next" or "same" line after
control structures.

Allowed values: ``'next'`` and ``'same'``

Default value: ``'same'``

``position_after_functions_and_oop_constructs``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Whether the opening brace should be placed on "next" or "same" line after classy
