All Implemented Interfaces:

ExpressionEvaluator

public class MappedNumericEvaluator<T extends ItemModel,K extends Comparable>
extends AbstractComparableExpressionEvaluator<Comparable>

Evaluates a numeric expression for a numeric attribute related with ItemModel. Left operand must be a map of Numeric values that refer to a ItemModel, i.e: Map - represents how many products of each type are contained in the order. Right operand - ItemQuantity - represents data that correspond to a single entry of such a map. If left operand contains an entry represented by ItemModel in right operand, then the evaluation of corresponding numeric values is delegated to NumericExpressionEvaluator
