Name: python-singledispatchmethod
Version: 1.0
Release: 1
Summary: Backport of @functools.singledispatchmethod to Python 2.7-3.7.
License: MIT
URL: https://github.com/ikalnytskyi/singledispatchmethod
Source0: https://mirrors.nju.edu.cn/pypi/web/packages/be/e0/20ecc21453d7f052ee04d0d9b3305798e0f6afc619885c9aaee4ba86b25c/singledispatchmethod-1.0.tar.gz
BuildArch: noarch
%description
Backport of ``@functools.singledispatchmethod`` decorator [1]_ from
Python 3.8 to Python 2.7-3.7. These are merely ~30 lines of code, but
why bother yourself with copypasta?
$ pip install singledispatchmethod
The decorator transforms a method into a single-dispatch [2]_ generic
function [3]_. Note that since the dispatch happens on the type of the
first non-self or non-cls argument, you have to create your function
accordingly:
from singledispatchmethod import singledispatchmethod
class Negator:
@singledispatchmethod
def neg(self, arg):
raise NotImplementedError("Cannot negate a")
@neg.register
def _(self, arg: int):
return -arg
@neg.register
def _(self, arg: bool):
return not arg
``@singledispatchmethod`` supports nesting with other decorators such as
``@classmethod``. However, in order to expose ``dispatcher.register``,
``@singledispatchmethod`` must be the *outer most* decorator. Here is
the ``Negator`` class with the ``neg`` methods being class bound:
from singledispatchmethod import singledispatchmethod
class Negator:
@singledispatchmethod
@classmethod
def neg(cls, arg):
raise NotImplementedError("Cannot negate a")
@neg.register
@classmethod
def _(cls, arg: int):
return -arg
@neg.register
@classmethod
def _(cls, arg: bool):
return not arg
The same pattern can be used for other similar decorators, such as
``@staticmethod`` or ``@abstractmethod``. Please note, since
``@singledispatchmethod`` decorator is based on
``@functools.singledispatch``, type annotations are supported by
``dispatcher.register`` only since Python 3.7.
