Method Detail
-
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 classDTMAxisTraverser
- 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 context, 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 classDTMAxisTraverser
- Parameters:
context
- 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.
