- class uproot.cache.LRUCache(limit)
- Parameters:
limit (None or int) – Number of objects to allow in the cache before evicting the least-recently used. If None, this cache never evicts.
LRUCache is a
MutableMapping
that evicts the least-recently used objects when thecurrent
number of objects exceeds thelimit
.Get and set (or explicitly remove) items with
MutableMapping
syntax: square bracket subscripting.LRUCache is thread-safe for all options: getting, setting, deleting, iterating, listing keys, values, and items.
This cache is insensitive to the size of the objects it stores, and hence is a better
object_cache
than anarray_cache
.
sizeof
- classmethod LRUCache.sizeof(obj)
The “size of” an object in this cache is always exactly 1.
limit
- LRUCache.limit
Number of objects to allow in the cache before evicting the least-recently used. If None, this cache never evicts.
current
- LRUCache.current
Current number of items in the cache.
keys
- LRUCache.keys()
Returns a copy of the keys currently in the cache, in least-recently used order.
The list ascends from least-recently used to most-recently used: index
0
is the least-recently used and index-1
is the most-recently used.(Calling this method does not change the order.)
values
- LRUCache.values()
Returns a copy of the values currently in the cache, in least-recently used order.
The list ascends from least-recently used to most-recently used: index
0
is the least-recently used and index-1
is the most-recently used.(Calling this method does not change the order.)
items
- LRUCache.items()
Returns a copy of the items currently in the cache, in least-recently used order.
The list ascends from least-recently used to most-recently used: index
0
is the least-recently used and index-1
is the most-recently used.(Calling this method does not change the order.)
