    • Method Detail

      • readBytes

        public void readBytes​(byte[] b,
                              int offset,
                              int len)
                       throws IOException
        Description copied from class: DataInput
        Reads a specified number of bytes into an array at the specified offset.
        Specified by:
        readBytes in class DataInput
        b - the array to read bytes into
        offset - the offset in the array to start storing bytes
        len - the number of bytes to read

      • length

        public long length()
        Description copied from class: IndexInput
        The number of bytes in the file.

        length in class IndexInput
      • clone

        public IndexInput clone()
        Description copied from class: IndexInput
        Returns a clone of this stream.

        Clones of a stream access the same data, and are positioned at the same point as the stream they were cloned from.

        Expert: Subclasses must ensure that clones may be positioned at different points in the input from each other and from the stream they were cloned from.

        Warning: Lucene never closes cloned IndexInputs, it will only call IndexInput.close() on the original object.

        If you access the cloned IndexInput after closing the original object, any readXXX methods will throw AlreadyClosedException.

        This method is NOT thread safe, so if the current IndexInput is being used by one thread while clone is called by another, disaster could strike.
