WindowsDirectory.WindowsIndexInput
public WindowsDirectory.WindowsIndexInput(File file,
int bufferSize)
throws IOException
- Throws:
IOException
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 intooffset
- the offset in the array to start storing byteslength
- 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:
