Package org.apache.lucene.mockfile

Support for testing/debugging with virtual filesystems

The primary classes are:

• LeakFS: Fails tests if they leave open filehandles.
• VerboseFS: Prints destructive filesystem operations to infostream.
• WindowsFS: Acts like windows.
• DisableFsyncFS: Makes actual fsync calls a no-op.
• ExtrasFS: Adds 'bonus' files to directories.
• ShuffleFS: Directory listings in an unpredictable but deterministic order.

Class Summary

Class	Description
DisableFsyncFS	Disables actual calls to fsync.
ExtrasFS	Adds extra files/subdirectories when directories are created.
FilterAsynchronousFileChannel	A FilterAsynchronousFileChannel contains another AsynchronousFileChannel, which it uses as its basic source of data, possibly transforming the data along the way or providing additional functionality.
FilterDirectoryStream	A FilterDirectoryStream contains another DirectoryStream, which it uses as its basic source of data, possibly transforming the data along the way or providing additional functionality.
FilterFileChannel	A FilterFileChannel contains another FileChannel, which it uses as its basic source of data, possibly transforming the data along the way or providing additional functionality.
FilterFileStore	A FilterFileStore contains another FileStore, which it uses as its basic source of data, possibly transforming the data along the way or providing additional functionality.
FilterFileSystem	A FilterFileSystem contains another FileSystem, which it uses as its basic source of data, possibly transforming the data along the way or providing additional functionality.
FilterFileSystemProvider	A FilterFileSystemProvider contains another FileSystemProvider, which it uses as its basic source of data, possibly transforming the data along the way or providing additional functionality.
FilterInputStream2	A FilterInputStream2 contains another InputStream, which it uses as its basic source of data, possibly transforming the data along the way or providing additional functionality.
FilterOutputStream2	A FilterOutputStream2 contains another OutputStream, which it uses as its basic source of data, possibly transforming the data along the way or providing additional functionality.
FilterPath	A FilterPath contains another Path, which it uses as its basic source of data, possibly transforming the data along the way or providing additional functionality.
FilterSeekableByteChannel	A FilterSeekableByteChannel contains another SeekableByteChannel, which it uses as its basic source of data, possibly transforming the data along the way or providing additional functionality.
HandleLimitFS	FileSystem that throws exception if file handles in use exceeds a specified limit
HandleTrackingFS	Base class for tracking file handles.
LeakFS	FileSystem that tracks open handles.
MockFileSystemTestCase	Base class for testing mockfilesystems.
ShuffleFS	Gives an unpredictable, but deterministic order to directory listings.
VerboseFS	FileSystem that records all major destructive filesystem activities.
VirusCheckingFS	Acts like a virus checker on Windows, where random programs may open the files you just wrote in an unfriendly way preventing deletion (e.g.
WindowsFS	FileSystem that (imperfectly) acts like windows.
