Known Subclasses:

xml_.STD_ANON_lang

Base class for union datatypes.

This class descends only from simpleTypeDefinition. A pyxb.LogicError is raised if an attempt is made to construct an instance of a subclass of STD_union. Values consistent with the member types are constructed using the Factory class method. Values are validated using the _ValidatedMember class method.

Subclasses must provide a class variable _MemberTypes which is a tuple of legal members of the union.

Method Details

[hide private]

Factory(cls, *args, **kw)
Class Method

Given a value, attempt to create an instance of some member of this union. The first instance which can be legally created is returned.

Parameters:

_validate_constraints - If True (default), any constructed value is checked against constraints applied to the union as well as the member type.

Raises:

pyxb.BadTypeValueError - no member type will permit creation of an instance from the parameters in args and kw.

Overrides: _TypeBinding_mixin.Factory

_ValidatedMember(cls, value)
Class Method

Validate the given value as a potential union member.

Raises:

pyxb.BadTypeValueError - the value is not an instance of a member type.

init(self, *args, **kw)
(Constructor)

source code

Initialize a newly created STD instance.

Usually there is one positional argument, which is a value that can be converted to the underlying Python type.

Parameters:

_validate_constraints - If True (default), the newly constructed value is checked against its constraining facets.

Overrides: object.__init__

XsdLiteral(cls, value)
