openstack.block_storage.v2.volume¶

The Volume Class¶

The Volume class inherits from Resource.

class openstack.block_storage.v2.volume.Volume(_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.
