Constructor Detail

### WindowsDirectory.WindowsIndexInput

    public WindowsDirectory.WindowsIndexInput(File file,
                                              int bufferSize)
                                       throws IOException

Throws:
  `IOException`

Method Detail

### readInternal

    protected void readInternal(byte[] b,
                                int offset,
                                int length)
                         throws IOException

  Description copied from class: `BufferedIndexInput`
  Expert: implements buffer refill. Reads bytes from the current position in the input.

  Specified by:
    `readInternal` in class `BufferedIndexInput`
  Parameters:
    `b` - the array to read bytes into
    `offset` - the offset in the array to start storing bytes
    `length` - the number of bytes to read
  Throws:
    `IOException`

### seekInternal

    protected void seekInternal(long pos)
                         throws IOException

  Description copied from class: `BufferedIndexInput`
  Expert: implements seek. Sets current position in this file, where the next `BufferedIndexInput.readInternal(byte[],int,int)` will occur.

  Specified by:
    `seekInternal` in class `BufferedIndexInput`
  Throws:
    `IOException`
  See Also:
    `BufferedIndexInput.readInternal(byte[],int,int)`

### close

    public void close()
               throws IOException

  Description copied from class: `IndexInput`
  Closes the stream to further operations.

  Specified by:
    `close` in interface `Closeable`
  Specified by:
    `close` in class `IndexInput`
  Throws:
    `IOException`

### length

    public long length()

  Description copied from class: `IndexInput`
  The number of bytes in the file.

  Specified by:
    `length` in class `IndexInput`

### clone

    public Object clone()

  Description copied from class: `DataInput`
  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.

  Overrides:
    `clone` in class `BufferedIndexInput`
