public final class LiteBlockingWaitStrategy extends Object implements WaitStrategy
BlockingWaitStrategy
that attempts to elide conditional wake-ups when
the lock is uncontended. Shows performance improvements on microbenchmarks. However this
wait strategy should be considered experimental as I have not full proved the correctness of
the lock elision code.Constructor and Description |
