Package-level declarations

Types

BaseChunkedDirectoryTestCase

abstract class BaseChunkedDirectoryTestCase : BaseDirectoryTestCase

Base class for Directories that "chunk" the input into blocks.

BaseDirectoryTestCase

abstract class BaseDirectoryTestCase : LuceneTestCase

Base class for Directory implementations.

BaseDirectoryWrapper

open class BaseDirectoryWrapper(delegate: Directory) : FilterDirectory

Minimal port of Lucene's BaseDirectoryWrapper. Only provides basic tracking of open state and a toggle for running checkIndex on close. The actual checkIndex logic is not implemented yet.

BaseLockFactoryTestCase

abstract class BaseLockFactoryTestCase : LuceneTestCase

Base class for per-LockFactory tests.

CorruptingIndexOutput

open class CorruptingIndexOutput(dir: Directory, byteToCorrupt: Long, out: IndexOutput) : FilterIndexOutput

Corrupts one bit of a file after close.

MockDirectoryWrapper

class MockDirectoryWrapper(random: Random, delegate: Directory) : BaseDirectoryWrapper, FailurePathProbe

This is a Directory Wrapper that adds methods intended to be used only by unit tests. It also adds a number of features useful for testing:

MockIndexInputWrapper

open class MockIndexInputWrapper(dir: MockDirectoryWrapper, val name: String, delegate: IndexInput, parent: MockIndexInputWrapper?, readAdvice: ReadAdvice, confined: Boolean) : FilterIndexInput

Used by MockDirectoryWrapper to create an input stream that keeps track of when it's been closed.

MockIndexOutputWrapper

class MockIndexOutputWrapper(dir: MockDirectoryWrapper, out: IndexOutput, var name: String?) : FilterIndexOutput, FailurePathProbe

Used to create an output stream that will throw an IOException on fake disk full, track max disk space actually used, and maybe throw random IOExceptions.

RawDirectoryWrapper

class RawDirectoryWrapper(delegate: Directory) : BaseDirectoryWrapper

Delegates all operations, even optional ones, to the wrapped directory.

SerialIOCountingDirectory

class SerialIOCountingDirectory(in: Directory) : FilterDirectory

A Directory wrapper that counts the number of times that Lucene may wait for I/O to return serially. Lower counts mean that Lucene better takes advantage of I/O parallelism.
