Function Documentation

def abc.abstractmethod

(

funcobj

)

A decorator indicating abstract methods.

Requires that the metaclass is ABCMeta or derived from it.  A
class that has a metaclass derived from ABCMeta cannot be
instantiated unless all of its abstract methods are overridden.
The abstract methods can be called using any of the normal
'super' call mechanisms.

Usage:

    class C:
        __metaclass__ = ABCMeta
        @abstractmethod
        def my_abstract_method(self, ...):
            ...
