Method Details

newBuffer

protected void newBuffer(byte[] newBuffer)

Overrides:

newBuffer in class BufferedIndexInput

readInternal

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

len - 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
