NodePointer | getCurrentNodePointer() - Returns the current context node.
|
Pointer | getSingleNodePointer() - Returns the first encountered Pointer that matches the current
context's criteria.
|
boolean | nextNode() - Returns true if there is another object in the current set.
|
void | reset() - Sets current position = 0, which is the pre-iteration state.
|
boolean | setPosition(int position) - Moves the current position to the specified index.

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
reset
public void reset()
Sets current position = 0, which is the pre-iteration state.
- reset 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.
