org.nuiton.validator.bean.simple.SimpleBeanValidator<O>

public class SimpleBeanValidator<O>
extends AbstractValidator<O>

Validator for a javaBean object. A such validator is designed to validate to keep the validation of a bean, means the bean is attached to the validator (via the context field context. A such validator is also a JavaBean and you can listen his states modifications via the classic java bean api. Note: The SimpleBeanValidator should never be used for validation in a service approch since it needs to keep a reference to the bean to validate.

  public static <O> SimpleBeanValidator<O> newValidator(java.lang.Class<O> type, java.lang.String context, NuitonValidatorScope... scopes) throws java.lang.NullPointerException
  
  Obtain a new SimpleBeanValidator for the given parameters. Note: It will use the default provider of NuitonValidator
  
  Type Parameters:
  
  O - type of bean to validate
  
  Parameters:
  
  type - type of bean to validate
  
  context - context of validation
  
  scopes - authorized scopes (if null, will use all scopes)
  
  Returns:
  
  the new instanciated SimpleBeanValidator.
  
  Throws:
  
  java.lang.NullPointerException - if type is null

- validate
  
  protected void validate()
  
  il faut eviter le code re-intrant (durant une validation, une autre est demandee). Pour cela on fait la validation dans un thread, et tant que la premiere validation n'est pas fini, on ne repond pas aux solicitations. Cette method est public pour permettre de force une validation par programmation, ce qui est utile par exemple si le bean ne supporte pas les PropertyChangeListener Note: la methode est protected et on utilise la methode doValidate() car la méthode ne modifie pas les etats internes et cela en rend son utilisation delicate (le validateur entre dans un etat incoherent par rapport aux messages envoyés).
- fireFieldChanged
  
  protected void fireFieldChanged(SimpleBeanValidatorEvent evt)
- mergeMessages
  
  protected void mergeMessages(NuitonValidatorResult newMessages)
