- All Implemented Interfaces:
- Closeable
public class SimpleFSDirectory
- extends FSDirectory
A straightforward implementation of FSDirectory
using java.io.RandomAccessFile. However, this class has
poor concurrent performance (multiple threads will
bottleneck) as it synchronizes when multiple threads
read from the same file. It's usually better to use
NIOFSDirectory
or MMapDirectory
instead.
