openpathsampling.netcdfplus.cache.WeakLRUCache

class openpathsampling.netcdfplus.cache.WeakLRUCache(size_limit=100, weak_type='value')

Implements a cache that keeps weak references to all elements

In addition it uses a simple Least Recently Used Cache to make sure a portion of the last used elements are still present. Usually this number is 100.

__init__(size_limit=100, weak_type='value')

Parameters:

size_limit (int) – integer that defines the size of the LRU cache. Default is 100.

Methods

__init__([size_limit, weak_type])	param size_limit: integer that defines the size of the LRU cache. Default is 100.
clear()
get(item[, default])	get value by key if it exists, None else
get_silent(item)	Return item from the without reordering the LRU
keys()
transfer(old_cache)	Transfer values between caches
values()

Attributes

count	the number of strong references int : the number of weak references
size	the maximal number of strong references, -1 if infinite int : the maximal number of weak references, -1 if infinite
