__init__(name: str, max_size: int)

beginEpoch()

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()

Evicts a sequence of objects if the queue is full.

countActiveSize() → int

Returns the total size of the pages that were enqueued since the last call to beginEpoch().

evictTo(target_size: int)

Evicts a sequence of objects until the queue fits within the indicated target size, regardless of its normal max size.

getMaxSize() → int

Returns the max size of all objects that are allowed to be active on the LRU.

getTotalSize() → int

Returns the total size of all objects currently active on the LRU.

output(out: ostream)

setMaxSize(max_size: int)

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.
