org.hibernate.annotationfactory.AnnotationProxy

A concrete implementation of Annotation that pretends it is a "real" source code annotation. It's also an InvocationHandler.

When you create an AnnotationProxy, you must initialize it with an AnnotationDescriptor. The adapter checks that the provided elements are the same elements defined in the annotation interface. However, it does not check that their values are the right type. If you omit an element, the adapter will use the default value for that element from the annotation interface, if it exists. If no default exists, it will throw an exception.

Warning: this class does not implement hashCode() and equals() - it just uses the ones it inherits from Object. This means that an AnnotationProxy does not follow the recommendations of the Annotation javadoc about these two methods. That's why you should never mix AnnotationProxies with "real" annotations. For example, don't put them into the same Collection. @author Paolo Perrotta @author Davide Marchignoli @see java.lang.annotation.Annotation
