Class EventAnnotationStripper

java.lang.Object
  net.sf.saxon.evpull.EventAnnotationStripper

All Implemented Interfaces:

EventIterator, PullEvent

public class EventAnnotationStripper
extends Object
implements EventIterator

This class is an EventIterator that filters a stream of pull events setting the type annotation on element nodes to xs:untyped and on attribute nodes to xs:untypedAtomic

Constructor Summary

EventAnnotationStripper(EventIterator base)
Create an EventAnnotationStripper

Method Summary

boolean	isFlatSequence() Determine whether the EventIterator returns a flat sequence of events, or whether it can return nested event iterators
PullEvent	next() Get the next event in the sequence

Constructor Detail

EventAnnotationStripper

public EventAnnotationStripper(EventIterator base)

Create an EventAnnotationStripper

Parameters:

base - the stream of events whose type annotations are to be stripped (set to untyped)

Method Detail

next

public PullEvent next()
               throws XPathException

Get the next event in the sequence

Specified by:

next in interface EventIterator

Returns:

the next event, or null when the sequence is exhausted. Note that since an EventIterator is itself a PullEvent, this method may return a nested iterator.

Throws:

XPathException - if a dynamic evaluation error occurs

isFlatSequence

public boolean isFlatSequence()

Determine whether the EventIterator returns a flat sequence of events, or whether it can return nested event iterators

Specified by:

isFlatSequence in interface EventIterator

Returns:

true if the next() method is guaranteed never to return an EventIterator
