Examples of com.sleepycat.je.latch.SharedLatch

com.sleepycat.je.latch.SharedLatch
Simple thread-based non-transactional reader-writer/shared-exclusive latch. Latches provide simple exclusive or shared transient locks on objects. Latches are expected to be held for short, defined periods of time. No deadlock detection is provided so it is the caller's responsibility to sequence latch acquisition in an ordered fashion to avoid deadlocks.
