openpathsampling.netcdfplus.cache.WeakLRUCache
- class openpathsampling.netcdfplus.cache.WeakLRUCache(size_limit=100, weak_type='value')[source]
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')[source]
- Parameters:
size_limit (int) – integer that defines the size of the LRU cache. Default is 100.
