Method Details

position

public long position()
              throws IOException

Specified by:

position in interface HasPosition

Throws:

IOException

position

public void position(long pos)
              throws IOException

Specified by:

position in interface HasPosition

Throws:

IOException

cloneObject

public SeekableReadableChannel<A> cloneObject()

Description copied from interface: SeekableReadableChannel

Optional operation. Open a new channel to the underlying source at the same position as this channel. The returned channel is an independent entity and needs to be closed separatedly. Opening a channel this way may be faster than opening a new channel at the source because information about this channel may be re-used (e.g. held pages and pointers into internal data structures)

Specified by:

cloneObject in interface SeekableReadableChannel<A>
