Constructor Details
- SimpleFilteredIterator
  
  public SimpleFilteredIterator(XPathContext outerContext, BooleanEvaluator condition)
  
  Construct a AxisFilter
  
  Parameters:
  
  outerContext - the underlying iterator that returns all the nodes on a required axis.
  
  condition - a test that is applied to each node returned by the underlying SequenceIterator; only those items that pass the NodeTest are returned by the filter
Method Details
- next
  
  public Item next()
  
  Description copied from interface: SequenceIterator
  
  Get the next item in the sequence. This method changes the state of the iterator.
  
  Specified by:
  
  next in interface SequenceIterator
  
  Returns:
  
  the next item, or null if there are no more items. Once a call on next() has returned null, no further calls should be made. The preferred action for an iterator if subsequent calls on next() are made is to return null again, and all implementations within Saxon follow this rule.
