protected List<AggregateImpl>	LatticeImpl.getChildren(AggregateImpl aggregate) Returns a list of aggregates which can be computed from a given aggregate by dropping one attribute.
List<AggregateImpl>	LatticeImpl.getMaterializedAggregates()
List<AggregateImpl>	Lattice.getMaterializedAggregates()
protected List<AggregateImpl>	LatticeImpl.getParents(AggregateImpl aggregate) Returns a list of aggregates which can be computed from a given aggregate by adding one attribute.
