      • AxisFilter

        public AxisFilter​(AxisIterator base,
                          NodePredicate test)
        Construct a AxisFilter
        base - the underlying iterator that returns all the nodes on a required axis. This must not be an atomizing iterator!
        test - a NodeTest that is applied to each node returned by the underlying AxisIterator; only those nodes that pass the NodeTest are returned by the AxisFilter

      • next

        public NodeInfo 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 AxisIterator
        Specified by:
        next in interface SequenceIterator
        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.
