public interface EventIterator extends PullEvent
An iterator over a sequence of events

  • Method Summary

    Modifier and Type
    Method
    Description
    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

  • Method Details

    • next

      PullEvent next() throws XPathException
      Get the next event in the sequence
      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

      boolean isFlatSequence()
      Determine whether the EventIterator returns a flat sequence of events, or whether it can return nested event iterators
      Returns:
      true if the next() method is guaranteed never to return an EventIterator
