Constructor Detail

DescendantAxisIterator

public DescendantAxisIterator(SteppingNode start,
                              boolean includeSelf,
                              NodeTest test)

Create an iterator over the descendant or descendant-or-self axis

Parameters:

start - the root of the subtree whose descendants are required

includeSelf - true if this is the descendant-or-self axis

test - the node-test that selected nodes must satisfy

Method Detail

next

public SteppingNode next()

Description copied from interface: SequenceIterator

Get the next item in the sequence. This method changes the state of the iterator.

Specified by:

next in interface SequenceIterator

Specified by:

next in interface AxisIterator

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.
