Class PullToStax

java.lang.Object
  extended by com.saxonica.pull.PullToStax
All Implemented Interfaces:
XMLStreamConstants, XMLStreamReader
public class PullToStax
extends Object
implements XMLStreamReader

This class bridges PullProvider events to XMLStreamReader (Stax) events. That is, it acts as an XMLStreamReader, fetching the underlying data from a PullProvider.

A PullProvider may provide access to any XDM sequence, whereas an XMLStreamReader always reads a document. The conversion of a sequence to a document follows the rules for "normalizing" a sequence in the Serialization specification: for example, atomic values are converted into text nodes, with adjacent atomic values being space-separated.
