JDOMNodeIterator
public JDOMNodeIterator(NodePointer parent, NodeTest nodeTest, boolean reverse, NodePointer startWith)
Create a new JDOMNodeIterator.- Parameters:
parent
- pointernodeTest
- testreverse
- whether to iterate in reversestartWith
- starting pointer

Method Detail

getNodePointer
public NodePointer getNodePointer()
Description copied from interface:NodeIterator
Get the NodePointer at the current position.- Specified by:
getNodePointer
in interfaceNodeIterator
- Returns:
- NodePointer
-
getPosition
public int getPosition()
Description copied from interface:NodeIterator
Get the current iterator position.- Specified by:
getPosition
in interfaceNodeIterator
- Returns:
- int position
-
setPosition
public boolean setPosition(int position)
Description copied from interface:NodeIterator
Set the new current position.- Specified by:
setPosition
in interfaceNodeIterator
- Parameters:
position
- the position to set- Returns:
true
if there is a node atposition
.
-
previous
private boolean previous()
This is actually never invoked during the normal evaluation of xpaths - an iterator is always going forward, never backwards. So, this is implemented only for completeness and perhaps for those who use these iterators outside of XPath evaluation.- Returns:
- boolean
-
next
private boolean next()
Iterate to next pointer.- Returns:
- whether valid
-
testChild
private boolean testChild()
Test a child node.- Returns:
- whether test passes.
