        PyType

PyType(self, name, type_check, type_class, stringify=None) User defined type.

Named type that contains a type check function and a type class that inherits from ObjectifiedDataElement. The type check must take a string as argument and raise ValueError or TypeError if it cannot handle the string value. It may be None in which case it is not considered for type guessing.

Example:

PyType('int', int, MyIntClass).register()

Note that the order in which types are registered matters. The first matching type will be used.

Instance Methods

[hide private]

__init__(self, name, type_check, type_class, stringify=None)
x.__init__(...) initializes x; see help(type(x)) for signature

a new object with type S, a subtype of T

__new__(T, S, ...)

__repr__(x)
repr(x)

unregister(self)

Inherited from object: __delattr__, __format__, __getattribute__, __hash__, __reduce__, __reduce_ex__, __setattr__, __sizeof__, __str__, __subclasshook__

Method Details

init(self, name, type_check, type_class, stringify=None)
(Constructor)

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__

new(T, S, ...)

Returns: a new object with type S, a subtype of T
Overrides: object.__new__

repr(x)
(Representation operator)

repr(x)

Overrides: object.__repr__

register(self, before=None, after=None)

The additional keyword arguments 'before' and 'after' accept a sequence of type names that must appear before/after the new type in the type list. If any of them is not currently known, it is simply ignored. Raises ValueError if the dependencies cannot be fulfilled.

Note that this must be set before registering the type!
