Class PullEventTracer
java.lang.Object
net.sf.saxon.evpull.PullEventTracer
- EventIterator, PullEvent
public class PullEventTracer
extends java.lang.Object
Diagnostic class to display the sequence of events reported by an EventIterator
boolean | isFlatSequence() - Determine whether the EventIterator returns a flat sequence of events, or whether it can return
nested event iterators
|
static void | main(String[] args) - Main method for testing only
|
PullEvent | next() - Get the next event in the sequence
|
PullEventTracer
public PullEventTracer(EventIterator base,
Configuration config)
Create a tracer for pull events
base
- the event iterator whose events are to be tracedconfig
- the Saxon configuration
isFlatSequence
public boolean isFlatSequence()
Determine whether the EventIterator returns a flat sequence of events, or whether it can return
nested event iterators
- isFlatSequence in interface EventIterator
- true if the next() method is guaranteed never to return an EventIterator
main
public static void main(String[] args)
throws Exception
Main method for testing only
next
public PullEvent next()
throws XPathException
Get the next event in the sequence
- next in interface EventIterator
- 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.
