Annotation Type EntityValidator

@Retention(value=RUNTIME)
@Target(value=TYPE)
@ValidatorClass(value=EntityValidatorValidator.class)
public @interface EntityValidator

This validator allows to define a validation at entity level.

Applies to entities.

When you need to make a validation on several properties at a time, and that validation does not correspond logically with any of them, then you can use this type of validation.
Example:

  @Entity
  @EntityValidator(InvoiceDetailValidator.class,
    properties= { 
      @PropertyValue(name="invoice"), 
      @PropertyValue(name="oid"), 
      @PropertyValue(name="product"),
      @PropertyValue(name="unitPrice")
    }
  )
  public class InvoiceDetail {
  ...
 

EntityValidator is also implemented as a Hibernate validation, therefore it's executed when you save using JPA or Hibernate API, with the exception of onlyOnCreate=true, in this last case the validation is only applied when you save with OpenXava (using MapFacade or standard OX actions).
