Java/JAXB: Unmarshall Xml to specific subclass based on an attribute

Question

Is it possible to use JAXB to unmarshall xml to a specific Java class based on an attribute of the xml?

Answer 1

The annotation @XmlElements enables you to specify which tag corresponds with which subclass.

@XmlElements({
    @XmlElement(name="square", type=Square.class),
    @XmlElement(name="triangle", type=Triangle.class)
})
public List getShape() {
    return shape;
}
