com.icl.saxon.om.PrependIterator
All Implemented Interfaces:
LastPositionFinder, AxisEnumeration, NodeEnumeration

public class PrependIterator extends Object implements AxisEnumeration
An iterator over nodes, that prepends a given node to the nodes returned by another iterator. Used to modify an iterator over axis A to one that iterates over A-OR-SELF.

    • hasMoreElements

      public boolean hasMoreElements()
      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()
      Get the next item in the sequence.
      Specified by:
      nextElement in interface AxisEnumeration
      Specified by:
      nextElement in interface NodeEnumeration
      Returns:
      the next Item. If there are no more nodes, return null.
    • isPeer

      public boolean isPeer()
      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
    • isReverseSorted

      public boolean isReverseSorted()
      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.
    • isSorted

      public boolean isSorted()
      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.
    • getLastPosition

      public int getLastPosition()
      Get the last position
      Specified by:
      getLastPosition in interface AxisEnumeration
      Specified by:
      getLastPosition in interface LastPositionFinder
