public abstract class MtmAggregationStep
extends MtmObject

An MtmObject that specifies the SQL function and other aspects of operations to perform when Oracle OLAP aggregates the values of the measures of an MtmUnsolvedCube for the dimension hierarchies of the MtmDimensionMap objects of this MtmAggregationStep. The MtmDimensionMap objects of an MtmUnsolvedCube are always instances of MtmUnsolvedLevelHierarchyMap.

Each MtmUnsolvedLevelHierarchyMap of the MtmUnsolvedCube is associated with one and only one MtmAggregationStep. An MtmAggregationStep can specify the aggregation operations for one or more of the MtmUnsolvedLevelHierarchyMap objects.

You can use methods of an MtmObjectFactory to create instances of the concrete subclasses of MtmAggregationStep.

Method Summary
`void`	`addDimensionMap(MtmDimensionMap dimensionMap)` Adds an `MtmDimensionMap` to this `MtmAggregationStep`.
`java.util.List`	`getDimensionMaps()` Gets the `MtmDimensionMap` objects for which this `MtmAggregationStep` specifies the aggregation operations.
`void`	`removeDimensionMap(MtmDimensionMap dimMap)` Removes an `MtmDimensionMap` from this `MtmAggregationStep`.
