AncestorEnumeration
public AncestorEnumeration(NodeInfo start, boolean includeSelf)
Create an iterator over the ancestor or ancestor-or-self axis- Parameters:
start
- the initial context nodeincludeSelf
- true if the "self" node is to be included
-
-
Method Detail
-
advance
public void advance()
Description copied from class:Navigator.BaseEnumeration
The advance() method must be provided in each concrete implementation. It must leave the variable current set to the next node to be returned in the iteration, or to null if there are no more nodes to be returned.- Specified by:
advance
in classNavigator.BaseEnumeration
-
getAnother
public SequenceIterator getAnother()
Description copied from interface:UnfailingIterator
Get another iterator over the same sequence of items, positioned at the start of the sequence. It must be possible to call this method at any time, whether none, some, or all of the items in the original iterator have been read. The method is non-destructive: it does not change the state of the original iterator.- Specified by:
getAnother

in classNavigator.BaseEnumeration
- Returns:
- a new iterator over the same sequence
