All Implemented Interfaces:
Closeable, AutoCloseable, SequenceIterator
Enclosing class:
FilterExpression.FilterExprElaborator
public static class FilterExpression.FilterExprElaborator.PositionalFilteredIterator extends Object implements SequenceIterator
An iterator for a filter expression in which the predicate is capable of evaluating as a number (in which case it needs to be compared with the context position, rather than being converted to a boolean)

  • Constructor Details

    • PositionalFilteredIterator

      public PositionalFilteredIterator(XPathContext outerContext, PullEvaluator 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

    • 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.
