IFencedLock Interface

Namespace: Hazelcast.CP
Assembly: Hazelcast.Net.dll

Represents a linearizable, distributed, reentrant implementation of the Java Lock.

public interface IFencedLock : ICPDistributedObject, IDistributedObject, IAsyncDisposable
Inherited Members
Remarks

The IFencedLock is CP with respect to the CAP principle. It works on top of the Raft consensus algorithm. It offers linearizability during crash-stop failures and network partitions. If a network partition occurs, it remains available on at most one side of the partition.

A IFencedLock works within the context of a LockContext.

Properties

Name Description
InvalidFence

Gets the identifier representing an invalid fence.

Methods

Name Description
