Examples of javax.xml.bind.UnmarshallerHandler

javax.xml.bind.UnmarshallerHandler

This interface is the SAX {@link org.xml.sax.ContentHandler}representation of an {@link javax.xml.bind.Unmarshaller}, as returned by {@link javax.xml.bind.Unmarshaller#getUnmarshallerHandler()}. It can be embedded into a stack of SAX handlers, for example within Apache Cocoon.

The UnmarshallerHandler is reusable: The startDocument() method is expected to perform a reinitialization. Like most other SAX handlers, the UnmarshallerHandler is never thread safe.
