Method Open
Open(DirectoryInfo)
Creates an FSDirectory instance, trying to pick the best implementation given the current environment. The directory returned uses the NativeFSLockFactory.
Currently this returns MMapDirectory for most Solaris and Windows 64-bit runtimes, NIOFSDirectory for other non-Windows runtimes, and SimpleFSDirectory for other runtimes on Windows. It is highly recommended that you consult the implementation's documentation for your platform before using this method.
NOTE: this method may suddenly change which implementation is returned from release to release, in the event that higher performance defaults become possible; if the precise implementation is important to your application, please instantiate it directly, instead. For optimal performance you should consider using MMapDirectory on 64 bit runtimes.
See FSDirectory.
