Class NIOFSDirectory
java.lang.Object
org.apache.lucene.store.Directory
org.apache.lucene.store.FSDirectory
org.apache.lucene.store.NIOFSDirectory
public class NIOFSDirectory
- extends FSDirectory
An FSDirectory
implementation that uses
java.nio's FileChannel's positional read, which allows
multiple threads to read from the same file without
synchronizing.
This class only uses FileChannel when reading; writing
is achieved with SimpleFSDirectory.SimpleFSIndexOutput
.
NOTE: NIOFSDirectory is not recommended on Windows because of a bug
in how FileChannel.read is implemented in Sun's JRE.
Inside of the implementation the position is apparently
synchronized. See here
for details.
