Class BracketedDocumentIterator

java.lang.Object

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.
