Class LockFactory
Base class for Locking implementation. Directory uses instances of this class to implement locking.
Lucene uses NativeFSLockFactory by default for FSDirectory-based index directories.
Special care needs to be taken if you change the locking implementation: First be certain that no writer is in fact writing to the index otherwise you can easily corrupt your index. Be sure to do the LockFactory change on all Lucene instances and clean up all leftover lock files before starting the new configuration for the first time. Different implementations can not work together!
If you suspect that some LockFactory implementation is not working properly in your environment, you can easily test it by using VerifyingLockFactory, LockVerifyServer and LockStressTest.

Properties

|---|---|
| LockPrefix | Gets or Sets the prefix in use for all locks created in this LockFactory. This is normally called once, when a Directory gets this LockFactory instance. However, you can also call this (after this instance is assigned to a Directory) to override the prefix in use. This is helpful if you're running Lucene on machines that have different mount points for the same shared directory. |
