The options types
===================

Description of Options
----------------------

All the constructors take a ``name`` and a ``doc`` argument as first
arguments to give the option or option group a name and to document it.
Most constructors take a ``default`` argument that specifies the default
value of the option. If this argument is not supplied the default value
is assumed to be ``None``.

The `Option` base class
-------------------------

It's the abstract base class for almost all options (except the symblink).

.. _optioninit:

.. autoclass:: Option
    :special-members:
    :members:

All option types
------------------

.. autoclass:: BoolOption
    :private-members:

.. autoclass:: IntOption
    :private-members:

.. autoclass:: FloatOption
    :private-members:

.. autoclass:: StrOption
    :private-members:


.. autoclass:: SymLinkOption

    .. automethod:: __init__


``SymLinkOption`` redirects to another configuration option in the
configuration, that is :

- retrieves the value of the target,
- can set the value of the target too


.. autoclass:: IPOption

.. autoclass:: NetmaskOption

.. autoclass:: NetworkOption

.. autoclass:: DomainnameOption


.. autoclass:: ChoiceOption

    .. automethod:: __init__


.. _optdescr:

The `OptionDescription` class
-------------------------------

.. autoclass:: OptionDescription
    :special-members:
    :members:


If you need to access to an option object, you can do it with the 
OptionDescription object. Not only the value of the option by attribute access, 
but the option object itself that lives behind the scene. It can always be 
accessed internally. The option objects are in the `_children` 
`OptionDescription`'s attribute.
