Examples of javax.xml.bind.Unmarshaller

javax.xml.bind.Unmarshaller

A Unmarshaller is the opposite of the {@link Marshaller}: It takes as input XML in either of several representations (byte or character stream, DOM node, or a series of SAX events) and returns a JAXB object with the same contents.

If the JAXB user demands, the Unmarshaller may also validate the content tree that it sees.
