Class StepIterator
- Cloneable, DTMAxisIterator
public class StepIterator
A step iterator is used to evaluate expressions like "BOOK/TITLE".
A better name for this iterator would have been ParentIterator since
both "BOOK" and "TITLE" are steps in XPath lingo. Step iterators are
constructed from two other iterators which we are going to refer to
as "outer" and "inner". Every node from the outer iterator (the one
for BOOK in our example) is used to initialize the inner iterator.
After this initialization, every node from the inner iterator is
returned (in essence, implementing a "nested loop").

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