## Uses of Class
org.apache.lucene.store.LockFactory

Packages that use LockFactory
org.apache.lucene.store: Binary i/o API, used for all index data.
org.apache.lucene.util: Some utility classes.

### Uses of LockFactory in org.apache.lucene.store

Subclasses of LockFactory in org.apache.lucene.store
`class` `FSLockFactory` Base class for file system based locking implementation.
`class` `NativeFSLockFactory` Implements `LockFactory` using native OS file locks.
`class` `NoLockFactory` Use this `LockFactory` to disable locking entirely.
`class` `SimpleFSLockFactory` Implements `LockFactory` using `Files.createFile(java.nio.file.Path, java.nio.file.attribute.FileAttribute<?>...)`.
`class` `SingleInstanceLockFactory` Implements `LockFactory` for a single in-process instance, meaning all locking will take place through this one instance.
`class` `VerifyingLockFactory` A `LockFactory` that wraps another `LockFactory` and verifies that each lock obtain/release is "correct" (never results in two processes holding the lock at the same time).

Fields in org.apache.lucene.store declared as LockFactory
`protected LockFactory` BaseDirectory.`lockFactory` Holds the LockFactory instance (implements locking for this Directory instance).

Methods in org.apache.lucene.store with parameters of type LockFactory
`static FSDirectory` FSDirectory.`open(Path path, LockFactory lockFactory)` Just like `FSDirectory.open(Path)`, but allows you to also specify a custom `LockFactory`.

Constructors in org.apache.lucene.store with parameters of type LockFactory
Constructor and Description
`BaseDirectory(LockFactory lockFactory)` Sole constructor.
`ByteBuffersDirectory(LockFactory lockFactory)`
`ByteBuffersDirectory(LockFactory factory, Supplier<ByteBuffersDataOutput> bbOutputSupplier, BiFunction<String,ByteBuffersDataOutput,IndexInput> outputToInput)`
`FSDirectory(Path path, LockFactory lockFactory)` Create a new FSDirectory for the named location (ctor for subclasses).
`MMapDirectory(Path path, LockFactory lockFactory)` Create a new MMapDirectory for the named location.
`MMapDirectory(Path path, LockFactory lockFactory, int maxChunkSize)` Create a new MMapDirectory for the named location, specifying the maximum chunk size used for memory mapping.
`NIOFSDirectory(Path path, LockFactory lockFactory)` Create a new NIOFSDirectory for the named location.
`RAMDirectory(LockFactory lockFactory)` Deprecated. Constructs an empty `Directory` with the given `LockFactory`.
`SimpleFSDirectory(Path path, LockFactory lockFactory)` Deprecated. Create a new SimpleFSDirectory for the named location.
`VerifyingLockFactory(LockFactory lf, InputStream in, OutputStream out)`

### Uses of LockFactory in org.apache.lucene.util
