Throws:

IOException

FSDirectory.FSIndexInput

public FSDirectory.FSIndexInput(File path,
                                int bufferSize)
                         throws IOException

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 futher operations.

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: 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.

Overrides:
