public class FunctionExpressionImpl<X> extends ExpressionImpl<X>
Purpose: Contains the implementation of the Predicate interface of the JPA criteria API.
Description: The predicate forms the least specific expression node. Predicates result in boolean expressions that are combined to form the final expression.
