classmethod get_by_name_or_id(context, identity)¶

id¶

is_multiattach()¶

is_public¶

is_replicated()¶

model¶

alias of cinder.db.sqlalchemy.models.VolumeType

name¶

obj_load_attr(attrname)¶

Load an additional attribute from the real object.

This should load self.$attrname and cache any data that might be useful for future load operations.

obj_make_compatible(primitive, target_version)¶

Make an object representation compatible with a target version.

This is responsible for taking the primitive representation of an object and making it suitable for the given target_version. This may mean converting the format of object attributes, removing attributes that have been added since the target version, etc. In general:

• If a new version of an object adds a field, this routine should remove it for older versions.
• If a new version changed or restricted the format of a field, this should convert it back to something a client knowing only of the older version will tolerate.
• If an object that this object depends on is bumped, then this object should also take a version bump. Then, this routine should backlevel the dependent object (by calling its obj_make_compatible()) if the requested version of this object is older than the version where the new dependent object was added.

Parameters:	primitive – The result of obj_to_primitive() target_version – The version string requested by the recipient of the object
Raises:	oslo_versionedobjects.exception.UnsupportedObjectError if conversion is not possible for some reason

projects¶

qos_specs¶

qos_specs_id¶

save()¶

Save the changed fields back to the store.

This is optional for subclasses, but is presented here in the base class for consistency among those that do.
