Class AggregationKey

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

public class AggregationKey
extends java.lang.Object

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.
