Class SimpleResultTreeImpl.SimpleIterator

java.lang.Object

org.apache.xml.dtm.ref.DTMAxisIteratorBase

org.apache.xalan.xsltc.dom.SimpleResultTreeImpl.SimpleIterator

All Implemented Interfaces:

Cloneable, DTMAxisIterator

Enclosing class:

SimpleResultTreeImpl

public final class SimpleResultTreeImpl.SimpleIterator
extends DTMAxisIteratorBase

The SimpleIterator is designed to support the nodeset() extension function. It has a traversal direction parameter. The DOWN direction is used for child and descendant axes, while the UP direction is used for parent and ancestor axes. This iterator only handles two nodes (RTF_ROOT and RTF_TEXT). If the type is set, it will also match the node type with the given type.

Method Detail

next

public int next()

Description copied from interface: DTMAxisIterator

Get the next node in the iteration.

Returns:

The next node handle in the iteration, or END.

setStartNode

public DTMAxisIterator setStartNode(int nodeHandle)

Description copied from interface: DTMAxisIterator

Set start to END should 'close' the iterator, i.e. subsequent call to next() should return END.

Parameters:

nodeHandle - Sets the root of the iteration.

Returns:

A DTMAxisIterator set to the start of the iteration.

setMark

public void setMark()

Description copied from interface: DTMAxisIterator

Remembers the current node for the next call to gotoMark().

gotoMark

public void gotoMark()

Description copied from interface: DTMAxisIterator

Restores the current node remembered by setMark().
