Class | Description |
---|---|
BufferedIndexInput |
Base implementation class for buffered
IndexInput . |
BufferedIndexOutput |
Base implementation class for buffered
IndexOutput . |
ChecksumIndexInput |
Writes bytes through to a primary IndexOutput, computing
checksum as it goes.
|
ChecksumIndexOutput |
Writes bytes through to a primary IndexOutput, computing
checksum.
|
Directory |
A Directory is a flat list of files.
|
FileSwitchDirectory |
Expert: A Directory instance that switches files between
two other Directory instances.
|
FSDirectory | |
FSDirectory.FSIndexInput | Deprecated
Use SimpleFSDirectory.SimpleFSIndexInput instead
|
FSDirectory.FSIndexInput.Descriptor | Deprecated |
FSDirectory.FSIndexOutput | Deprecated
Use SimpleFSDirectory.SimpleFSIndexOutput instead
|
FSLockFactory |
Base class for file system based locking implementation.
|
IndexInput |
Abstract base class for input from a file in a
Directory . |
IndexOutput |
Abstract base class for output to a file in a Directory.
|
Lock |
An interprocess mutex lock.
|
Lock.With |
Utility class for executing code with exclusive access.
|
LockFactory |
Base class for Locking implementation.
|
LockStressTest |
Simple standalone tool that forever acquires & releases a
lock using a specific LockFactory.
|
LockVerifyServer |
Simple standalone server that must be running when you
use
VerifyingLockFactory . |
MMapDirectory |
File-based
Directory implementation that uses
mmap for reading, and SimpleFSDirectory.SimpleFSIndexOutput for writing. |
NativeFSLockFactory |
Implements
LockFactory using native OS file
locks. |
NIOFSDirectory |
An
FSDirectory implementation that uses
java.nio's FileChannel's positional read, which allows
multiple threads to read from the same file without
synchronizing. |
NIOFSDirectory.NIOFSIndexInput | |
NoLockFactory |
Use this
LockFactory to disable locking entirely. |
RAMDirectory |
A memory-resident
Directory implementation. |
RAMFile |
For Lucene internal use
|
RAMOutputStream |
A memory-resident
IndexOutput implementation. |
SimpleFSDirectory |
A straightforward implementation of
FSDirectory
using java.io.RandomAccessFile. |
SimpleFSDirectory.SimpleFSIndexInput | |
SimpleFSDirectory.SimpleFSIndexInput.Descriptor | |
SimpleFSDirectory.SimpleFSIndexOutput | |
SimpleFSLockFactory |
Implements
LockFactory using File.createNewFile() . |
SingleInstanceLockFactory |
Implements
LockFactory for a single in-process instance,
meaning all locking will take place through this one instance. |
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). |
Exception | Description |
---|---|
AlreadyClosedException |
This exception is thrown when there is an attempt to
access something that has already been closed.
|
LockObtainFailedException |
This exception is thrown when the
write.lock
could not be acquired. |
LockReleaseFailedException |
This exception is thrown when the
write.lock
could not be released. |
NoSuchDirectoryException |
This exception is thrown when you try to list a
non-existent directory.
