NodePointer | getCurrentNodePointer() - Returns the current context node.

NodeSet | getNodeSet() - Returns the list of all Pointers in this context for all positions
of the parent contexts.

boolean | nextNode() - Returns true if there is another object in the current set.

getNodeSet
public NodeSet getNodeSet()
Returns the list of all Pointers in this context for all positions
of the parent contexts. If there was an ongoing iteration over
this context, the method should not be called.
- getNodeSet in interface EvalContext
nextNode
public boolean nextNode()
Returns true if there is another object in the current set.
Switches the current position and node to the next object.
- nextNode in interface EvalContext
nextSet
public boolean nextSet()
Returns true if there is another sets of objects to interate over.
Resets the current position and node.
- nextSet in interface EvalContext
setPosition
public boolean setPosition(int position)
Moves the current position to the specified index. Used with integer
predicates to quickly get to the n'th element of the node set.
Returns false if the position is out of the node set range.
You can call it with 0 as the position argument to restart the iteration.
