"The <literal>Interceptor interface provides callbacks from the "

"manipulate properties of a persistent object before it is saved, updated, "
"deleted or loaded. One possible use for this is to track auditing "
"information. For example, the following <literal>Interceptor "
"automatically sets the <literal>createTimestamp when an "
"<literal>Auditable is created and updates the "
"<literal>lastUpdateTimestamp property when an Auditable brinda callbacks desde la sesión "
"a la aplicación, permitiendole a ésta última inspeccionar y/o manipular las "
"propiedades de un objeto persistente antes de que sea guardado, actualizado, "
"borrado o cargado. Un uso posible de esto es seguir la pista de la "
