Class DomainValidator

java.lang.Object

org.boon.messages.MessageSpecification

org.boon.validation.validators.BaseValidator

org.boon.validation.validators.DomainValidator

All Implemented Interfaces:

Serializable, NameAware, FieldValidator

public class DomainValidator
extends BaseValidator

This validator is designed for domain-driven validation of a group of child objects from a parent. For instance, a parent with a OneToMany relationship with a child may need to validate the child against the other children associated with the parent. In this scenario, the validation framework will invoke this validator when the @DomainValidation annotation is used on a field in the child object by invoking the parent object validation method identified by the "method" attribute. The parent object is identified by the "parentProperty" attribute. If the parent attribute is null or missing, then the validation method is presumed to exist in the child.

The validation method will be passed the child object and the field value as method.invoke(child, fieldValue)
