A python Function / Method OUTPUT cache system base on function Decorators.
Source code: https://github.com/hustcc/wrapcache
wrapcache
is a decorator that enables caching of return values for functions.
The cache keys are dependent completely on the arguments passed to the function. very simple to use.
Also has some API
to Programmatic
get cache or remove cache. Support python 2.6 ~ python3.5.
Here's an example of how you might use wrapcache:
import wrapcache
from time import sleep
import random
@wrapcache.wrapcache(timeout = 3)
def need_cache_function(input, t = 2, o = 3):
sleep(2)
return random.randint(1, 100)
if __name__ == "__main__":
for i in range(10):
sleep(1)
print(need_cache_function(1, t = 2, o = 3))
#get cache Programmatic
key_func = wrapcache.keyof(need_cache_function, 1, o = 3, t = 2)
print(wrapcache.get(key_func))
#remove cache Programmatic
print(wrapcache.remove(wrapcache.keyof(need_cache_function, 1, o = 3, t = 2)))
Three way to install:
easy_install wrapcache
or
pip install wrapcache
/pip3 install wrapcache
- Download from https://pypi.python.org/pypi/wrapcache/, and run
python setup.py install
.
- Manual installation: Put
wrapcache
folder into current directory orsite-packages
, thenimport wrapcache
to use.
import wrapcache
@wrapcache.wrapcache(timeout = 3)
def need_cache_function():
return 'hello wrapcache'
wrapcache.keyof(func, *args, **kws)
: get the key of function output cache.wrapcache.get(key, adapter = MemoryAdapter)
: get the value of cache.wrapcache.set(key, value, adapter = MemoryAdapter)
: set cache use code.wrapcache.remove(key, adapter = MemoryAdapter)
: remove a cache.wrapcache.flush(adapter = MemoryAdapter)
: clear all the cache.
The API 2~5, need to input a adapter
to set which db to flush.
- add redis and memcache supported.
