public @interface XmlSeeAlso
Java makes it impractical/impossible to list all sub-classes of
a given class. This often gets in a way of JAXB users, as it JAXB
cannot automatically list up the classes that need to be known
to JAXBContext.
For example, with the following class definitions:
class Animal {}
class Dog extends Animal {}
class Cat extends Animal {}
The user would be required to create JAXBContext as
JAXBContext.newInstance(Dog.class,Cat.class)
(Animal will be automatically picked up since Dog
and Cat refers to it.)
XmlSeeAlso annotation would allow you to write:
@XmlSeeAlso({Dog.class,Cat.class})
class Animal {}
class Dog extends Animal {}
class Cat extends Animal {}
This would allow you to do JAXBContext.newInstance(Animal.class). By the help of this annotation, JAXB implementations will be able to correctly bind Dog and Cat.
