Class AggregationKey

java.lang.Object
  mondrian.rolap.agg.AggregationKey

public class AggregationKey
extends Object

This class defines the column context that an Aggregation is computed for. Column context has two components: -- the column constraints which define the dimentionality of an Aggregation -- an orthogonal context for which the measures are defined. This context is sometimes referred to as the compound member predicates, and usually of the shape: OR(AND(column predicates)) Any column is only used in either column context or compound context, not both.
