Class Moraine

java.lang.Object
  rice.p2p.aggregation.Moraine

All Implemented Interfaces:

GCPast, Past, VersioningPast

public class Moraine

extends java.lang.Object

implements GCPast, VersioningPast

This Past takes 2 pasts, an old Past and a new Past. It treats the old Past as a backing store for the new Past. Pretty much it's only going to work with glacier, and maybe aggregation A Moraine is the hill of rubble (aggregate as it were) left behind at the edges of a glacier or at the end of a retreating glacier
