Class InversibleLock

java.lang.Object
org.opendaylight.controller.cluster.access.client.InversibleLock
@Beta public final class InversibleLock extends Object
A lock implementation which allows users to perform optimistic reads and validate them in a fashion similar to StampedLock. In case a read is contented with a write, the read side will throw an InversibleLockException, which the caller can catch and use to wait for the write to resolve.
