public abstract class AbstractComparableExpressionEvaluator<T extends Comparable>
extends AbstractExpressionEvaluator

Abstract common parent class for all expressions evaluators that deal with operands that represent Comparable values. Extend this type if you want to come up with own ExpressionEvaluator for Operands which value providers OperandValueProvider.getValueType(de.hybris.platform.btg.model.BTGOperandModel) return Comparable.
