Class XmlTokenStream

java.lang.Object

com.fasterxml.jackson.dataformat.xml.deser.XmlTokenStream

public class XmlTokenStream
extends Object

Simple helper class used on top of STAX XMLStreamReader 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
