public class Expression
extends java.lang.Object

Expression.java represents the expression string defined in the mapping xml. Based on the expression functions contains in the expression it is devided on following types: Expression.MATH type - contains only mathematical functions and variables Expression.SIMPLE type - contains only DataMapper functions and variables Expression.COMBINED - contains both DataMapper and mathematical functions and variables
