RepositoryLock (Apache Jackrabbit 2.22.0 API)

java.lang.Object
- org.apache.jackrabbit.core.util.RepositoryLock

All Implemented Interfaces:

RepositoryLockMechanism
```
public class RepositoryLock
extends Object
implements RepositoryLockMechanism
```
Exclusive lock on a repository home directory. This class encapsulates collective experience on how to acquire an exclusive lock on a given directory. The lock is expected to be exclusive both across process boundaries and within a single JVM. The lock mechanism must also work consistently on a variety of operating systems and JVM implementations.
