Class BracketedDocumentIterator

java.lang.Object
  extended by net.sf.saxon.evpull.BracketedDocumentIterator
All Implemented Interfaces:
EventIterator, PullEvent

public class BracketedDocumentIterator
extends Object
implements EventIterator

The class is an EventIterator that handles the events arising from a document node constructor: that is, the start/end event pair for the document node, bracketing a sequence of events for the content of the document.

This class does not normalize the content (for example by merging adjacent text nodes). That is the job of the ComplexContentProcessor.

Method Summary
