getFirstPotential
protected int getFirstPotential(int identity) Get the first potential identity that can be returned. This should be overridded by classes that need to return the self node.- Overrides:
getFirstPotential
in classDTMDefaultBaseTraversers.DescendantTraverser
- Parameters:
identity
- The node identity of the root context of the traversal.- Returns:
- The first potential node that can be in the traversal.
-
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.
