Examples of org.exist.storage.lock.ReentrantReadWriteLock

org.exist.storage.lock.ReentrantReadWriteLock
A lock with the same semantics as builtin Java synchronized locks: Once a thread has a lock, it can re-obtain it any number of times without blocking. The lock is made available to other threads when as many releases as acquires have occurred. The lock has a timeout: a read lock will be released if the timeout is reached.
