java.lang.Object
  net.sf.saxon.tree.iter.AxisIteratorImpl
      net.sf.saxon.tree.tiny.AncestorEnumeration

All Implemented Interfaces:

SequenceIterator, AxisIterator, UnfailingIterator

final class AncestorEnumeration
extends AxisIteratorImpl

This class enumerates the ancestor:: or ancestor-or-self:: axes, starting at a given node. The start node will never be the root.

Method Detail

next

public Item next()

Description copied from interface: SequenceIterator

Get the next item in the sequence. This method changes the state of the iterator, in particular it affects the result of subsequent calls of position() and current().

Returns:

the next item, or null if there are no more items. Once a call on next() has returned null, no further calls should be made. The preferred action for an iterator if subsequent calls on next() are made is to return null again, and all implementations within Saxon follow this rule.

getAnother

public SequenceIterator getAnother()

Get another enumeration of the same nodes

Returns:

a SequenceIterator that iterates over the same items, positioned before the first item
