Instructs JAXB to also bind other classes when binding this class.
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
.
