Description
Class Summary | |
---|---|
BaseDirectory | Base implementation for a concrete Directory . |
BufferedIndexInput | Base implementation class for buffered IndexInput . |
BufferedIndexOutput | Base implementation class for buffered IndexOutput . |
ByteArrayDataInput | DataInput backed by a byte array. |
ByteArrayDataOutput | DataOutput backed by a byte array. |
ChecksumIndexInput | Reads bytes through to a primary IndexInput, computing checksum as it goes. |
ChecksumIndexOutput | Writes bytes through to a primary IndexOutput, computing checksum. |
CompoundFileDirectory | Class for accessing a compound stream. |
CompoundFileDirectory.FileEntry | Offset/Length for a slice inside of a compound file |
DataInput | Abstract base class for performing read operations of Lucene's low-level data types. |
DataOutput | Abstract base class for performing write operations of Lucene's low-level data types. |
Directory | A Directory is a flat list of files. |
FileSwitchDirectory | Expert: A Directory instance that switches files between two other Directory instances. |
FilterDirectory | Directory implementation that delegates calls to another directory. |
FlushInfo | A FlushInfo provides information required for a FLUSH context. |
FSDirectory | Base class for Directory implementations that store index files in the file system. |
FSDirectory.FSIndexInput | Base class for reading input from a RandomAccessFile |
FSDirectory.FSIndexOutput | Writes output with RandomAccessFile.write(byte[], int, int) |
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. |
InputStreamDataInput | A DataInput wrapping a plain InputStream . |
IOContext | IOContext holds additional details on the merge/search context. |
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 . |
MergeInfo | A MergeInfo provides information required for a MERGE context. |
MMapDirectory | File-based Directory implementation that uses
mmap for reading, and FSDirectory.FSIndexOutput 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 | Reads bytes with FileChannel.read(ByteBuffer, long) |
NoLockFactory | Use this LockFactory to disable locking entirely. |
NRTCachingDirectory | Wraps a RAMDirectory
around any provided delegate directory, to
be used during NRT search. |
OutputStreamDataOutput | A DataOutput wrapping a plain OutputStream . |
RAMDirectory | A memory-resident Directory implementation. |
RAMFile | Represents a file in RAM as a list of byte[] buffers. |
RAMInputStream | A memory-resident IndexInput implementation. |
RAMOutputStream | A memory-resident IndexOutput implementation. |
RateLimitedDirectoryWrapper | A Directory wrapper that allows IndexOutput rate limiting using
IO context specific rate limiters . |
RateLimiter | Abstract base class to rate limit IO. |
RateLimiter.SimpleRateLimiter | Simple class to rate limit IO. |
SimpleFSDirectory | A straightforward implementation of FSDirectory
using java.io.RandomAccessFile. |
SimpleFSDirectory.SimpleFSIndexInput | Reads bytes with RandomAccessFile.seek(long) followed by
RandomAccessFile.read(byte[], int, int) . |
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. |
TrackingDirectoryWrapper | A delegating Directory that records which files were written to and deleted. |
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). |
Enum Summary | |
---|---|
IOContext.Context | Context is a enumerator which specifies the context in which the Directory is being used for. |
Exception Summary | |
---|---|
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. |
Binary i/o API, used for all index data.
