public class MtmWeightedAverageAggregationStep

extends MtmAggregationStep

An MtmAggregationStep that specifies a weighted average aggregation of the measure values for the node levels of the hierarchies of the dimensions of this MtmAggregationStep.

You can specify a weighting factor with the setWeight function. The weighting factor can be a constant, an expression, or an existing column. With the getIsHierarchical and setIsHierarchical methods, you can discover or specify whether this aggregation step includes null values in its averaging calculation.

You can create an instance of this class with the createMtmWeightedAverageAggregationStep method of an MtmObjectFactory.

acceptVisitor

public java.lang.Object acceptVisitor(MtmObjectVisitor visitor,
                                      java.lang.Object context)

Calls the visitMtmWeightedAverageAggregationStep method of the specified MtmObjectVisitor and passes that method this MtmWeightedAverageAggregationStep and the specified context object.

Parameters:

visitor - An MtmObjectVisitor.

context - An Object.

Returns:

The Object returned by the visitMtmWeightedAverageAggregationStep method.

Overrides:

acceptVisitor in class MtmObject

isHierarchical

public boolean isHierarchical()

Indicates whether Oracle OLAP includes null measure values in the count of values specified by the children of a node element of a dimension that it uses to calculate the average value for the node element.

Returns:

true if Oracle OLAP includes null measure values in the count of values, or false if it does not.

getWeight

public MtmValueExpression getWeight()

Gets the weighting factor to apply to the average values specified by this MtmWeightedAverageAggregationStep.

Returns:

An MtmValueExpression that specifies the weighting factor that applies to the average values specified by this MtmWeightedAverageAggregationStep.

setIsHierarchical

public void setIsHierarchical(boolean isHierarchical)

Specifies whether Oracle OLAP includes null measure values in the count of values specified by the children of a node element of a dimension that it uses to calculate the average value for the node element. Specify true if you want to include null measure values in the count of values. Specify false if you do not want to include null measure values in the count of values.

Parameters:

isHierarchical - A boolean that specifies whether to include null measure values in the count of values.

setWeight

public void setWeight(MtmValueExpression weight)

Specifies the weighting factor to apply to the average values specified by this MtmWeightedAverageAggregationStep. The weighting factor can be a constant, an expression, such as a custom expression that you create, or an column, such as an existing column in a table.

Parameters:

weight - An MtmValueExpression that specifies a weighting factor to apply to the average values specified by this MtmWeightedAverageAggregationStep.
