Class ValidationRegistryManagerImpl

java.lang.Object
  org.acegisecurity.domain.validation.ValidationRegistryManagerImpl

All Implemented Interfaces:

ValidationRegistryManager, BeanFactoryAware

public class ValidationRegistryManagerImpl
extends Object
implements ValidationRegistryManager, BeanFactoryAware

A basic implementation of ValidationRegistryManager.

Locates Validators registered in bean factory.

If more than one Validator can support a given object, the supporting Validators will be iterated and their bean factory defined bean names will be used to attempt to select the "best matching" Validator. The lowercase version of a given object's simplified class name will be searched within the bean names. If more than one Validator contains this search criteria, an exception will be thrown as the actual intended Validator is unidentifiable.

For example, say you had a PartyValidator which could validate com.foo.Party, and also its subclass, com.foo.Person. There is also a PersonValidator which can only validate Person. PartyValidator and PersonValidator are registered in the bean container as "partyValidator" and "personValidator". When ValidationRegistryManagerImpl is asked to return the Validator for Person, it will locate the two matching Validators in the bean container. As there are two matching, it will look at the lowercase representation of the bean names and see if either contain the lower simplified class name of the object being search for (com.foo.Person thus becomes simply "person"). ValidationRegistryManagerImpl will then correctly return the PersonValidator for Person. If the PartyValidator had been registered with an ambiguous bean name of say "personAndPartyValidator", both bean names would have matched and an exception would have been thrown.
