Package org.apache.lucene.store

Examples of org.apache.lucene.store.FSDirectory

Unfortunately, because of system peculiarities, there is no single overall best implementation. Therefore, we've added the {@link #open} method, to allow Lucene to choosethe best FSDirectory implementation given your environment, and the known limitations of each implementation. For users who have no reason to prefer a specific implementation, it's best to simply use {@link #open}. For all others, you should instantiate the desired implementation directly.

The locking implementation is by default {@link NativeFSLockFactory}, but can be changed by passing in a custom {@link LockFactory} instance. @see Directory
