Class FormulaRange

java.lang.Object
  com.inet.report.FormulaRange

All Implemented Interfaces:

com.inet.report.formula.Evaluable, java.io.Serializable

public class FormulaRange
extends java.lang.Object
implements com.inet.report.formula.Evaluable, java.io.Serializable

This class is the representation of a range, e.g. defined with a formula like '20 to_ 30'. A range can have one or two limits - a lower and/or a higher limit. Either limit can be set to be "inclusive" or "exclusive", that is, itself included in the range or not.
Note that if a range has only one limit, the range includes all values which are greater than the limit (if the limit is the lower limit), or less than the limit accordingly (if the limit is the higher limit).
Examples:

• 1 _to 2 will include all values between 1 and 2, including the 2 but NOT including 1. This range would be created by calling: new FormulaRange(new Integer(1),new Integer(2),false,true).
• upfrom_ DateTime(2006,3,1,0,0,0) will include all DateTime values after March 1st, 2006, 12 a.m., not including this datetime itself. This range would be created by calling: new FormulaRange(myDate,null,false,false)

An object of this class will used for the representation of prompt ranges, too. So, if you want to fill the value of a prompt field as range use an object of this class to do this.
