Class DescendantEnumeration

  • All Implemented Interfaces:
    LastPositionFinder, AxisEnumeration, NodeEnumeration

    final class DescendantEnumeration
    extends java.lang.Object
    implements AxisEnumeration
    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. The calling code must ensure that the start node is not an attribute or namespace node.

      • hasMoreElements

        public boolean hasMoreElements()
        Description copied from interface: AxisEnumeration
        Determine whether there are more nodes to come.
        (Note the term "Element" is used here in the sense of the standard Java Enumeration class, it has nothing to do with XML elements).
        Specified by:
        hasMoreElements in interface AxisEnumeration
        Specified by:
        hasMoreElements in interface NodeEnumeration
        Returns:
        true if there are more nodes
      • nextElement

        public NodeInfo nextElement()
        Description copied from interface: AxisEnumeration
        Get the next node in sequence.
        (Note the term "Element" is used here in the sense of the standard Java Enumeration class, it has nothing to do with XML elements).
        Specified by:
        nextElement in interface AxisEnumeration
        Specified by:
        nextElement in interface NodeEnumeration
        Returns:
        the next NodeInfo
      • isSorted

        public boolean isSorted()
        Description copied from interface: NodeEnumeration
        Determine whether the nodes returned by this enumeration are known to be in document order
        Specified by:
        isSorted in interface NodeEnumeration
        Returns:
        true if the nodes are guaranteed to be in document order.
      • isReverseSorted

        public boolean isReverseSorted()
        Description copied from interface: NodeEnumeration
        Determine whether the nodes returned by this enumeration are known to be in reverse document order.
        Specified by:
        isReverseSorted in interface NodeEnumeration
        Returns:
        true if the nodes are guaranteed to be in document order.
      • isPeer

        public boolean isPeer()
        Description copied from interface: NodeEnumeration
        Determine whether the nodes returned by this enumeration are known to be peers, that is, no node is a descendant or ancestor of another node. This significance of this property is that if a peer enumeration is applied to each node in a set derived from another peer enumeration, and if both enumerations are sorted, then the result is also sorted.
        Specified by:
        isPeer in interface NodeEnumeration
