- com.fasterxml.jackson.dataformat.xml.deser.XmlTokenStream
-
public class XmlTokenStream extends Object
Simple helper class used on top of STAXXMLStreamReader
to further abstract out all irrelevant details, and to expose equivalent of flat token stream with no "fluff" tokens (comments, processing instructions, mixed content) all of which is just to simplify actual higher-level conversion to JSON tokens
