Class TracingEventIterator
java.lang.Object
net.sf.saxon.evpull.TracingEventIterator
- EventIterator, PullEvent
public class TracingEventIterator
extends java.lang.Object
This class is a filter for a sequence of pull events; it returns the input sequence unchanged,
but traces execution to System.err
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

TracingEventIterator
public TracingEventIterator(EventIterator base)
Create an event iterator that traces all events received from the base sequence, and returns
them unchanged
base
- the iterator over the base sequence
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
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.
