Create a function for decorating Python exception classes. The decorator will add a new rule to the given error mapper that will map the class to the specified error name. Definition of the decorator: .. code-block:: python decorator(error_name, namespace=()) The decorator accepts a name of the DBus error and optionally a namespace of the DBus name. The namespace will be used as a prefix of the DBus name. Usage: .. code-block:: python # Create an error mapper. error_mapper = ErrorMapper() # Create a decorator for DBus errors and use it to map # the class ExampleError to the name my.example.Error. dbus_error = create_error_decorator(error_mapper) @dbus_error("my.example.Error") class ExampleError(DBusError): pass :param error_mapper: an error mapper :return: a decorator � c s$ t g |�� �R � � �� fdd�}|S )Nc s � � t| �d�� | S )N)�exception_type� error_name)�add_ruler )�cls)� error_mapperr r �0/usr/lib/python3.9/site-packages/dasbus/error.py� decoratedI s �z9get_error_decorator.<locals>.decorator.<locals>.decoratedr )r � namespacer �r )r r � decoratorF s z&get_error_decorator.<locals>.decorator)r r )r r r r r r # s # r c @ s e Zd ZdZdS )r zA default DBus error.N)�__name__� __module__� __qualname__�__doc__r r r r r U s r c @ sD e Zd ZdZg Zedd� �Zedd� �Zedd� �Zedd � �Z d S ) r z=Abstract rule for mapping a Python exception to a DBus error.c C s dS )z�Is this rule matching the given exception type? :param exception_type: a type of the Python error :return: True or False Nr ��selfr r r r � match_type_ s z AbstractErrorRule.match_typec C s dS )z�Get a DBus name for the given exception type. :param exception_type: a type of the Python error :return: a name of the DBus error Nr r r r r �get_nameh s zAbstractErrorRule.get_namec C s dS )z�Is this rule matching the given DBus error? :param error_name: a name of the DBus error :return: True or False Nr �r r r r r � match_nameq s z AbstractErrorRule.match_namec C s dS )z�Get an exception type of the given DBus error. param error_name: a name of the DBus error :return: a type of the Python error Nr r r r r �get_typez s zAbstractErrorRule.get_typeN) r r r r � __slots__r r r r r! r r r r r Z s r )� metaclassc @ s@ e Zd ZdZddgZdd� Zdd� Zdd � Zd d � Zd d � Z dS )r z4Rule for mapping a Python exception to a DBus error.�_exception_type� _error_namec C s || _ || _dS )aV Create a new error rule.
