Constraint, PropertyConstraint

public class PropertiesConstraint
extends AbstractPropertyConstraint

A constraint that returns the result of a boolean expression that tests two variable bean property values. For example, pet.ageAtFirstVisit > pet.currentAge

Constructor Summary

PropertiesConstraint(String propertyName, BinaryConstraint beanPropertyExpression, String otherPropertyName)
Creates a BeanPropertyExpression

Method Summary

BinaryConstraint	getConstraint()
String	getOtherPropertyName()
boolean	isCompoundRule() Does this property constraint effect more than one property?
boolean	isDependentOn(String propertyName) Returns true if this property constraint is dependent on the provided propertyName for test evaluation; that is, it should be retested when propertyName changes.
protected boolean	test(PropertyAccessStrategy domainObjectAccessStrategy)
String	toString()

Constructor Detail

PropertiesConstraint

public PropertiesConstraint(String propertyName,
                            BinaryConstraint beanPropertyExpression,
                            String otherPropertyName)

Creates a BeanPropertyExpression

Parameters:

propertyName - The first property participating in the expression.

beanPropertyExpression - The expression predicate that will test the two bean property values.

otherPropertyName - The second property participating in the expression.
