Class DescendantEnumeration

java.lang.Object

net.sf.saxon.om.AxisIteratorImpl

net.sf.saxon.tinytree.DescendantEnumeration

All Implemented Interfaces:

AtomizableIterator, AxisIterator, SequenceIterator

final class DescendantEnumeration
extends AxisIteratorImpl

This class supports both the descendant:: and descendant-or-self:: axes, which are identical except for the route to the first candidate node. It enumerates descendants of the specified node. The calling code must ensure that the start node is not an attribute or namespace node.

Constructor Detail

DescendantEnumeration

DescendantEnumeration(TinyTree doc,
                      TinyNodeImpl node,
                      NodeTest nodeTest,
                      boolean includeSelf)

Create an iterator over the descendant axis

Parameters:

doc - the containing TinyTree

node - the node whose descendants are required

nodeTest - test to be satisfied by each returned node

includeSelf - true if the start node is to be included

Method Detail

next

public Item next()

Description copied from interface: AxisIterator

Get the next item in the sequence.

Returns:

the next Item. If there are no more nodes, return null.

getAnother

public SequenceIterator getAnother()

Get another enumeration of the same nodes

Returns:

a new iterator over the same sequence
