The MaxAggOperator component is an instantiatable subclass of the AggOperator and defines an aggregation operation where the maximum value in a DataSet is identified.
Set the aggOperator property of the AggDescriptor object to this class to identify the maximum value in a DataSet, using the property settings stored in the AggDescriptor. Attach the AggDescriptor object to a Column component's agg property to access the data that the aggregation uses.
public boolean locate(ReadRow row)Locates the maximum value for the grouping column values specified in row. For example, if the grouping column is region and the max column is sales, calling this method moves to the highest sales value for a region.
