Class Navigator.AncestorEnumeration

All Implemented Interfaces:
AxisIterator, SequenceIterator, UnfailingIterator
Enclosing class:
Navigator

public static final class Navigator.AncestorEnumeration extends Navigator.BaseEnumeration
General-purpose implementation of the ancestor and ancestor-or-self axes
  • Constructor Details

    • AncestorEnumeration

      public AncestorEnumeration(NodeInfo start, boolean includeSelf)
      Create an iterator over the ancestor or ancestor-or-self axis
      Parameters:
      start - the initial context node
      includeSelf - true if the "self" node is to be included
  • Method Details

    • advance

      public void advance()
      Description copied from class: Navigator.BaseEnumeration
      The advance() method must be provided in each concrete implementation. It must leave the variable current set to the next node to be returned in the iteration, or to null if there are no more nodes to be returned.
      Specified by:
      advance in class Navigator.BaseEnumeration
    • getAnother

      public SequenceIterator getAnother()
      Description copied from interface: UnfailingIterator
      Get another iterator over the same sequence of items, positioned at the start of the sequence. It must be possible to call this method at any time, whether none, some, or all of the items in the original iterator have been read. The method is non-destructive: it does not change the state of the original iterator.

      getAnother in interface SequenceIterator
      Specified by:
      getAnother in interface UnfailingIterator
      Specified by:
      getAnother in class Navigator.BaseEnumeration
      Returns:
      a new iterator over the same sequence
