Field Detail

_currentNode

protected int _currentNode
Current iteration location. Usually this is the last location returned (starting point for the next() search); for single-node iterators it may instead be initialized to point to that single node.

DTMDefaultBaseIterators.RootIterator

public DTMDefaultBaseIterators.RootIterator()
Constructor RootIterator

Method Detail

setStartNode

public DTMAxisIterator setStartNode(int node)
Set start to END should 'close' the iterator, i.e. subsequent call to next() should return END.

Parameters:
node - Sets the root of the iteration.
Returns:
A DTMAxisIterator set to the start of the iteration.

next

public int next()
Get the next node in the iteration.

Returns:
The next node handle in the iteration, or END.

setMark

public void setMark()
Remembers the current node for the next call to gotoMark(). %REVIEW% Should this save _position too?


gotoMark

public void gotoMark()
Restores the current node remembered by setMark(). %REVEIW% Should this restore _position too?
