public abstract static class Unmarshaller.Listener extends Object
Unmarshaller to externally listen
for unmarshal events.
This class enables pre and post processing of an instance of a JAXB mapped class
as XML data is unmarshalled into it. The event callbacks are called when unmarshalling
XML content into a JAXBElement instance or a JAXB mapped class that represents a complex type definition.
The event callbacks are not called when unmarshalling to an instance of a
Java datatype that represents a simple type definition.
External listener is one of two different mechanisms for defining unmarshal event callbacks.
See Unmarshal Event Callbacks for an overview.
