Class DescendantIteratorSansText

  • All Implemented Interfaces:
    Closeable, AutoCloseable, SequenceIterator, AxisIterator

    final class DescendantIteratorSansText
    extends Object
    implements AxisIterator
    This class supports both the descendant:: and descendant-or-self:: axes, which are identical except for the route to the first candidate node. It enumerates descendants of the specified node. This version is for use when it is known that text nodes are not selected. The calling code must ensure that the start node is not an attribute or namespace node.

      • 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
        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.
