Method Detail

• readInternal

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

  IndexInput methods

  Specified by:

  readInternal in class BufferedIndexInput

  Parameters:

  b - the array to read bytes into

  offset - the offset in the array to start storing bytes

  len - the number of bytes to read

  Throws:

  IOException

• close

  public void close()
             throws IOException

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

  Specified by:

  close in interface AutoCloseable

  Specified by:

  close in interface Closeable

  Specified by:

  close in class IndexInput

  Throws:

  IOException

• seekInternal

  protected void seekInternal​(long position)

  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

  See Also:

  BufferedIndexInput.readInternal(byte[],int,int)

• 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

• copyBytes

  public void copyBytes​(IndexOutput out,
                        long numBytes)
                 throws IOException

  Description copied from class: IndexInput
  Copies numBytes bytes to the given IndexOutput.

  NOTE: this method uses an intermediate buffer to copy the bytes. Consider overriding it in your implementation, if you can make a better, optimized copy.

  NOTE ensure that there are enough bytes in the input to copy to output. Otherwise, different exceptions may be thrown, depending on the implementation.

  Overrides:

  copyBytes in class BufferedIndexInput

  Throws:

  IOException
