            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.

### __init__(self, name, type_check, type_class, stringify=None)
(Constructor)

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Overrides: object.__init__

### __new__(T, S, ...)

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

### __repr__(...)
(Representation operator)

repr(x)

Overrides: object.__repr__
  (inherited documentation)

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

Register the type.

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.

### xmlSchemaTypes

The list of XML Schema datatypes this Python type maps to.

Note that this must be set before registering the type!
