-
class
SimpleLru¶ Bases:
LinkedListNode,NamableAn implementation of a very simple LRU algorithm. Also see
AdaptiveLru.Inheritance diagram
-
__init__(name: str, max_size: size_t) → None¶
-
beginEpoch() → None¶ Marks the end of the previous epoch and the beginning of the next one. This will evict any objects that are pending eviction, and also update any internal bookkeeping.
-
considerEvict() → None¶ Evicts a sequence of objects if the queue is full.
-
countActiveSize() → size_t¶ Returns the total size of the pages that were enqueued since the last call to
beginEpoch().- Return type
size_t
-
evictTo(target_size: size_t) → None¶ Evicts a sequence of objects until the queue fits within the indicated target size, regardless of its normal max size.
-
getMaxSize() → size_t¶ Returns the max size of all objects that are allowed to be active on the LRU.
- Return type
size_t
-
getTotalSize() → size_t¶ Returns the total size of all objects currently active on the LRU.
- Return type
size_t
-
output(out: ostream) → None¶
-
setMaxSize(max_size: size_t) → None¶ Changes the max size of all objects that are allowed to be active on the LRU.
If the size is (size_t)-1, there is no limit.
-
validate() → bool¶ Checks that the LRU is internally self-consistent. Returns true if successful, false if there is some problem.
-
write(out: ostream, indent_level: int) → None¶
