public interface Segment extends org.aksw.commons.io.util.channel.ChannelFactory<Seekable>
A segment is a sequence of bytes with a fixed size. Channels provide access to this sequence using a linear position. Channels may maintain internal pointers corresponding to a position. This may speed up speed up relative read operations as e.g. lookup of the right bucket for consecutive reads can be skipped.
