seek

public void seek(long pos)
          throws IOException

Description copied from class: SeekableInputStream

Seek to a new position in the stream.

Specified by:

seek in class SeekableInputStream

Parameters:

pos - the new position to seek to

Throws:

IOException - if the underlying stream throws an IOException

getPos

public long getPos()
            throws IOException

Description copied from class: SeekableInputStream

Get the current position in the stream.

Specified by:

getPos in class SeekableInputStream

Returns:

the current position in bytes from the start of the stream

Throws:

IOException - if the underlying stream throws an IOException

readFully

public void readFully(byte[] b,

 int len)
               throws IOException

Description copied from class: SeekableInputStream

Read fully len bytes into the buffer b.

Specified by:

readFully in class SeekableInputStream

Parameters:

b - byte array

off - offset in the byte array

len - number of bytes to read

Throws:

IOException - – the stream has been closed and the contained input stream does not support reading after close, or another I/ O error occurs.
