    • Method Detail

      • isSimpleFSIndexInput

        public static boolean isSimpleFSIndexInput​(org.apache.lucene.store.IndexInput is)
        Returns true if the instance of the provided input stream is actually an SimpleFSIndexInput.
      • isSimpleFSIndexInputClone

        public static boolean isSimpleFSIndexInputClone​(org.apache.lucene.store.IndexInput is)
        Returns true if the provided input stream is an SimpleFSIndexInput and is a clone, that is it does not own its underlying file descriptor.
      • isSimpleFSIndexInputOpen

        public static boolean isSimpleFSIndexInputOpen​(org.apache.lucene.store.IndexInput is)
                                                throws IOException
        Given an instance of SimpleFSDirectory.SimpleFSIndexInput, this method returns true if the underlying file descriptor is valid, and false otherwise. This can be used to determine if the OS file has been closed. The descriptor becomes invalid when the non-clone instance of the SimpleFSIndexInput that owns this descriptor is closed. However, the descriptor may possibly become invalid in other ways as well.
        Throws:
        IOException
