PyType(self, name, type_check, type_class, stringify=None)
User defined type.
Named type that contains a type check function, a type class that
inherits from ObjectifiedDataElement and an optional "stringification"
function. 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. For registered
named types, the 'stringify' function (or unicode() if None) is used to
convert a Python object with type name 'name' to the string representation
stored in the XML tree.
Example:
PyType('int', int, MyIntClass).register()
Note that the order in which types are registered matters. The first
matching type will be used.
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)
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.
