get_cache(self, cache_name, miss_fn)

source code

Get an AsyncLRUCache object with the given name. If such an object does not exist, it will be created. Since the cache is permanent, this method can be called only once, e.g., in startService, and it value stored indefinitely.

Parameters:

cache_name - name of the cache (usually the name of the type of object it stores)
miss_fn - miss function for the cache; see AsyncLRUCache constructor.

Returns:

AsyncLRUCache instance
