public class DTMDefaultBaseIterators.PrecedingIterator
extends DTMDefaultBaseIterators.InternalAxisIteratorBase

Iterator that returns preceding nodes of a given node. This includes the node set {root+1, start-1}, but excludes all ancestors, attributes, and namespace nodes.

Constructor Detail

DTMDefaultBaseIterators.PrecedingIterator

public DTMDefaultBaseIterators.PrecedingIterator()
Method Detail

isReverse

public boolean isReverse()
True if this iterator has a reversed axis.
Returns:
true since this iterator is a reversed axis.
Overrides:
isReverse in class DTMAxisIteratorBase

cloneIterator

public DTMAxisIterator cloneIterator()
Returns a deep copy of this iterator. The cloned iterator is not reset.
Returns:
a deep copy of this iterator.
Overrides:
cloneIterator in class DTMAxisIteratorBase

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.

reset

public DTMAxisIterator reset()
Resets the iterator to the last start node.
Returns:
A DTMAxisIterator, which may or may not be the same as this iterator.
Overrides:
reset in class DTMAxisIteratorBase

setMark

public void setMark()
Overrides:
setMark in class DTMDefaultBaseIterators.InternalAxisIteratorBase

gotoMark

public void gotoMark()
Overrides:
gotoMark in class DTMDefaultBaseIterators.InternalAxisIteratorBase
