public class: MMapDirectory [javadoc | source]

java.lang.Object
   org.apache.lucene.store.Directory
      org.apache.lucene.store.FSDirectory
         org.apache.lucene.store.MMapDirectory

File-based Directory implementation that uses mmap for input.

To use this, invoke Java with the System property org.apache.lucene.FSDirectory.class set to org.apache.lucene.store.MMapDirectory. This will cause FSDirectory#getDirectory(File,boolean) to return instances of this class.
