Object version field

Each service has its set of objects, each with a version attached. When a client attempts to call an object method, the server checks to see if the version of that object matches (in a compatible way) its object implementation. If so, cool, and if not, fail.

This version is allowed to have three parts, X.Y.Z, where the .Z element is reserved for stable branch backports. The .Z is ignored for the purposes of triggering a backport, which means anything changed under a .Z must be additive and non-destructive such that a node that knows about X.Y can consider X.Y.Z equivalent.

destroy(force=False)

Deletes the QoS spec.

Parameters:

force – when force is True, all volume_type mappings for this QoS are deleted. When force is False and volume_type mappings still exist, a QoSSpecsInUse exception is thrown

fields: MutableMapping[str, Field[Any]] = {'consumer': QoSConsumerValues(default=back-end,nullable=False,valid_values=('back-end', 'front-end', 'both')), 'created_at': DateTime(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=True), 'deleted': Boolean(default=False,nullable=True), 'deleted_at': DateTime(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=True), 'id': UUID(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=False), 'name': String(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=False), 'specs': Dict(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=True), 'updated_at': DateTime(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=True), 'volume_types': Object(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=True)}

The fields present in this object as key:field pairs.

For example:

fields = {
    'foo': obj_fields.IntegerField(),
    'bar': obj_fields.StringField(),
}

obj_get_changes()

Returns a dict of changed fields and their new values.

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_reset_changes(fields=None, recursive=False)

Reset the list of fields that have been changed.

Parameters:

• fields – List of fields to reset, or “all” if None.

• recursive – Call obj_reset_changes(recursive=True) on any sub-objects within the list of fields being reset.

This is NOT “revert to previous values”.

Specifying fields on recursive resets will only be honored at the top level. Everything below the top will reset all.

obj_what_changed()

Returns a set of fields that have been modified.

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.
