public final class SimpleResultTreeImpl.SimpleIterator extends DTMAxisIteratorBase
The SimpleIterator is designed to support the nodeset() extension function. It has a traversal direction parameter. The DOWN direction is used for child and descendant axes, while the UP direction is used for parent and ancestor axes. This iterator only handles two nodes (RTF_ROOT and RTF_TEXT). If the type is set, it will also match the node type with the given type.

next
public int next()
Description copied from interface:DTMAxisIterator
Get the next node in the iteration.- Returns:
- The next node handle in the iteration, or END.
-
setStartNode
public DTMAxisIterator setStartNode(int nodeHandle)
Description copied from interface:DTMAxisIterator
Set start to END should 'close' the iterator, i.e. subsequent call to next() should return END.- Parameters:
nodeHandle
- Sets the root of the iteration.- Returns:
- A DTMAxisIterator set to the start of the iteration.
-
setMark
public void setMark()
Description copied from interface:DTMAxisIterator
Remembers the current node for the next call to gotoMark().
-
gotoMark
public void gotoMark()
