    Method
    Description
    int
    first(int context)
    By the nature of the stateless traversal, the context node can not be returned or the iteration will go into an infinate loop.

    first(int current, int expandedTypeID)
    By the nature of the stateless traversal, the context node can not be returned or the iteration will go into an infinate loop.
    int
    next(int context, int current)
    Traverse to the next node after the current node.
    int
    next(int context, int current, int expandedTypeID)
    Traverse to the next node after the current node that is matched by the extended type ID.

    • first

      public int first(int context)
      By the nature of the stateless traversal, the context node can not be returned or the iteration will go into an infinate loop. So to traverse an axis, the first function must be used to get the first node.

      This method needs to be overloaded only by those axis that process the self node.

      Overrides:
      first in class DTMAxisTraverser
      Parameters:
      context - The context node of this traversal. This is the point that the traversal starts from.
      Returns:
      the first node in the traversal.
    • first

      public int first(int current, int expandedTypeID)
      By the nature of the stateless traversal, the context node can not be returned or the iteration will go into an infinate loop. So to traverse an axis, the first function must be used to get the first node.

      This method needs to be overloaded only by those axis that process the self node.

      Overrides:
      first in class DTMAxisTraverser
      Parameters:
      current - The context node of this traversal. This is the point of origin for the traversal -- its "root node" or starting point.
      expandedTypeID - The extended type ID that must match.
      Returns:
      the first node in the traversal.
    • next

      public int next(int context, int current)
      Traverse to the next node after the current node.
      Specified by:
      next in class DTMAxisTraverser
      Parameters:
      context - The context node of this traversal. This is the point of origin for the traversal -- its "root node" or starting point.
      current - The current node of the traversal. This is the last known location in the traversal, typically the node-handle returned by the previous traversal step. For the first traversal step, context should be set equal to current. Note that in order to test whether context is in the set, you must use the first() method instead.
      Returns:
      the next node in the iteration, or DTM.NULL.

    • next

      public int next(int context, int current, int expandedTypeID)
      Traverse to the next node after the current node that is matched by the extended type ID.
      Specified by:
      next in class DTMAxisTraverser
      Parameters:
      context - The context node of this traversal. This is the point of origin for the traversal -- its "root node" or starting point.
      current - The current node of the traversal. This is the last known location in the traversal, typically the node-handle returned by the previous traversal step. For the first traversal step, context should be set equal to current. Note that in order to test whether context is in the set, you must use the first() method instead.
      expandedTypeID - The extended type ID that must match.
      Returns:
