methodtools 0.1.1

Expand standard functools to methods

Expand functools features to methods, classmethods, staticmethods and even for (unofficial) hybrid methods.

Use methodtools module instead of functools module. Than it will work as you expected.

from methodtools import lru_cache

class A(object):

    # cached method. the storage lifetime follows `self` object
    @lru_cache()
    def cached_method(self, args):
        ...

    # cached classmethod. the storage lifetime follows `A` class
    @lru_cache()  # the order is important!
    @classmethod  # always lru_cache on top of classmethod
    def cached_classmethod(self, args):
        ...

    # cached staticmethod. the storage lifetime follows `A` class
    @lru_cache()  # the order is important!
    @staticmethod  # always lru_cache on top of classmethod
    def cached_staticmethod(self, args):
        ...

@lru_cache()  # just same as functools.lru_cache
def cached_function():
    ...

Documentation

For now, methodtools only provides lru_cache. See above for example. See documentation of functools.lru_cache for arguments details.

Installation

PyPI is the recommended way.

$ pip install methodtools
