Introduction

Function decorator that helps to cache/memoize the result of a function/method.

This package contains following decorators.

  • cache: cache the result of the function globally.
  • instance_cache: cache the result of a method in the instance (self)
  • clear_instance_cache: clear the method results cached on the instance.

And one function.

  • clear_cache: clear the global function cache.

Tested on python 2.7 and python 3.4.

For quick start, check the tutorial section of this page. Check test.py for detail examples.

Installation

pip install cachez

Tutorial

  • To cache the result of the a function globally, decorate the function with cache.
@cache
def foo(x, y):
    ...
  • To clear the global cache, call clear_cache().
clear_cache()
  • To cache the result of the method in the instance, decorate the method with instance_cache. To clear the method cache on the instance, decorate your clear method with clear_instance_cache.
class Foo(object):
    @instance_cache
    def bar(a, b):
        ...

    @clear_instance_cache
    def clear():
        ...
  • To persist the function return value, use persisted decorator. This decorator takes input parameter which specify when the cache will expire. The default value for cache expiration is set to 1 day.
class Foo(object):
    @persisted()
    def default_persist_for_1_day(x):
        ...

    @persisted(seconds=5)
    def persist_return_value_for_5_seconds(y):
        ...
  • The default persist folder is set to ~/.cachez. You could customize it by calling set_persist_folder.
