Navigator.PrecedingEnumeration

                                      boolean includeAncestors)

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 class Navigator.BaseEnumeration

getAnother

public SequenceIterator getAnother()

Description copied from interface: AxisIterator

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.
