Class Validators.NullObjectIfNullValidator

java.lang.Object

atg.service.validator.Validators.ValidatorImpl<java.lang.Object>

atg.service.validator.Validators.NullObjectIfNullValidator

All Implemented Interfaces:

Validator<java.lang.Object>, Validators.ValidatorWrapper<java.lang.Object>

Enclosing interface:

Validators

public static class Validators.NullObjectIfNullValidator
extends Validators.ValidatorImpl<java.lang.Object>
implements Validators.ValidatorWrapper<java.lang.Object>

A simple validator that wraps another validator. If the incoming property value is null, returns NULL_OBJECT. Otherwise, delegates to the wrapped validator. Using this class should make it straight forward add "NULL_OBJECT" behavior to existing Validators via nesting.

validateBeanProperty

public java.lang.Object validateBeanProperty(java.lang.String pPropertyName,
                                             java.lang.Object pBean,

validateBeanProperty in class Validators.ValidatorImpl<java.lang.Object>

Parameters:

pPropertyName - the property of pBean to validate

pBean - the bean to fetch pPropertyName from and validate

pContext - the current validation context.

Returns:

the validated (and possibly converted) value. May return null for invalid property data. May return ValidatorConstants.NULL_OBJECT indicating the that target property should be updated to null.
