| Method Summary | |
|---|---|
NodePointer |
getCurrentNodePointer()
Returns the current context node. |
boolean |
isChildOrderingRequired()
Even if this context has the natural ordering and therefore does not require collecting and sorting all nodes prior to returning them, such operation may be required for any child context. |
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. |
