# openstack.network.v2.extension

## The Extension Class

The `Extension` class inherits from `Resource`.

class openstack.network.v2.extension.Extension(_synchronized=False, connection=None, **attrs)

  The base resource

  Parameters:

    - _synchronized (bool) – This is not intended to be used directly. See `new()` and `existing()`.

    - connection (openstack.connection.Connection) – Reference to the Connection being used. Defaults to None to allow Resource objects to be used without an active Connection, such as in unit tests. Use of `self._connection` in Resource code should protect itself with a check for None.
