repoze.lru 0.2

API

Creating an LRUCache object:

from repoze.lru import LRUCache
cache = LRUCache(100) # 100 max length

Retrieving from an LRUCache object:

cache.get('nonexisting', 'foo') # will return 'foo'
cache.get('nonexisting') # will return None
cache.get('existing') # will return the value for existing

Adding to an LRUCache object:

cache.put('key', 'value') # will add the key 'key' with the value 'value'

Clearing an LRUCache:

cache.clear()

Decorator

A lru_cache decorator exists. All values passed to the decorated function must be hashable. It does not support keyword arguments:

from repoze.lru import lru_cache

@lru_cache(500)
def expensive_function(*arg):
    pass

Each function decorated with the lru_cache decorator uses its own cache related to that function.
