fields¶
-
class
oslo_versionedobjects.fields.
BaseEnumField
(**kwargs)¶ Base class for all enum field types
This class should not be directly instantiated. Instead subclass it and set AUTO_TYPE to be a SomeEnum() where SomeEnum is a subclass of Enum.
-
class
oslo_versionedobjects.fields.
CoercedDict
(*args, **kwargs)¶ Dict which coerces its values
Dict implementation which overrides all element-adding methods and coercing the element(s) being added to the required element type
-
class
oslo_versionedobjects.fields.
CoercedList
(*args, **kwargs)¶ List which coerces its elements
List implementation which overrides all element-adding methods and coercing the element(s) being added to the required element type
-
class
oslo_versionedobjects.fields.
CoercedSet
(*args, **kwargs)¶ Set which coerces its values
Dict implementation which overrides all element-adding methods and coercing the element(s) being added to the required element type
-
class
oslo_versionedobjects.fields.
DictProxyField
(dict_field_name, key_type=<type 'int'>)¶ Descriptor allowing us to assign pinning data as a dict of key_types
This allows us to have an object field that will be a dict of key_type keys, allowing that will convert back to string-keyed dict.
This will take care of the conversion while the dict field will make sure that we store the raw json-serializable data on the object.
key_type should return a type that unambiguously responds to six.text_type so that calling key_type on it yields the same thing.

class
oslo_versionedobjects.fields.
EnumField
(valid_values, **kwargs)¶ Anonymous enum field type
This class allows for anonymous enum types to be declared, simply by passing in a list of valid values to its constructor. It is generally preferrable though, to create an explicit named enum type by sub-classing the BaseEnumField type directly.
