Examples of org.apache.lucene.store.SimpleFSDirectory

org.apache.lucene.store.SimpleFSDirectory
A straightforward implementation of {@link 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 {@link NIOFSDirectory} or {@link MMapDirectory} instead.
