Contents
Arguments
threaded - true if list should be thread-safe.
root - performance parameter (see above).
maxLevel - performance parameter (see above).
flushLimit - max deleted items to keep cached before
forcing a flush.
freeValue - callback made whenever a value is flushed.
ctx - context to pass to <freeValue>.
Description
Returns a new skip list. If <threaded> is true, list is multi-thread safe. <root> and <maxLevel>
determine performance and expected size (see discussion above). <flushLimit> is for threaded lists and
determines the maximum number of deleted items to keep cached during concurrent searches. Once the limit
is reached, new concurrent reads are blocked until all deleted items are flushed.
MT-Level: Safe.
