biz.chitec.quarterback.util.logic
Class BooleanCompareExpr

java.lang.Object
  biz.chitec.quarterback.util.logic.SmartCompareExpr
      biz.chitec.quarterback.util.logic.BooleanCompareExpr

All Implemented Interfaces:

java.lang.Cloneable, LogicExpr

public class BooleanCompareExpr

extends SmartCompareExpr

Compares a value to a given boolean value. The comparator can handle that the given value should not be taken into consideration at all, i.e. it does not matter whether the actual value of the data to be compared is true or false. This is the case for the string parameter to be empty or null. This class is especially for database comparisons. Note that this can be moved later to QJCC.
