Class SimpleNodeList

java.lang.Object
  org.jdesktop.dom.SimpleNodeList

All Implemented Interfaces:

Iterable<Node>, NodeList

public class SimpleNodeList
extends Object
implements NodeList, Iterable<Node>

An implementation of NodeList which also implements Iterable. This allows you to use a SimpleNodeList in an enhanced for loop, such as:

  SimpleNodeList nodes = ...;
  for (Node n : nodes) {
      System.out.println(n.getTextContent());
  }
 

SimpleNodeList wraps a source NodeList. Thus, any NodeList can be adapted for use with enhanced for loops by wrapping it in a SimpleNodeList.

Constructor Summary

SimpleNodeList(List<Node> nodes)
Create a new SimpleNodeList that wraps the given nodes

SimpleNodeList(Node... nodes)
Create a new SimpleNodeList that wraps the given nodes

SimpleNodeList(NodeList list)
Creates a new instance of SimpleNodeList.

Method Summary

int	getLength() The number of nodes in the list.
Node	item(int index) Returns the indexth item in the collection.
Iterator<Node>	iterator() Returns an iterator over a set of elements of type T.

Constructor Detail

SimpleNodeList

public SimpleNodeList(NodeList list)

Creates a new instance of SimpleNodeList.

Parameters:

list - the NodeList to wrap.

SimpleNodeList

public SimpleNodeList(List<Node> nodes)

Create a new SimpleNodeList that wraps the given nodes

Parameters:

nodes - the nodes to wrap

SimpleNodeList

public SimpleNodeList(Node... nodes)

Create a new SimpleNodeList that wraps the given nodes

Parameters:

nodes - the nodes to wrap

Method Detail

item

public Node item(int index)

Description copied from interface: org.w3c.dom.NodeList

Returns the indexth item in the collection. If index is greater than or equal to the number of nodes in the list, this returns null.

Specified by:

item in interface NodeList

Parameters:

index - Index into the collection.

Returns:

The node at the indexth position in the NodeList, or null if that is not a valid index.

getLength

public int getLength()

Description copied from interface: org.w3c.dom.NodeList

The number of nodes in the list. The range of valid child node indices is 0 to length-1 inclusive.

Specified by:

getLength in interface NodeList

iterator

public Iterator<Node> iterator()

Description copied from interface: java.lang.Iterable

Returns an iterator over a set of elements of type T.

Specified by:

iterator in interface Iterable<Node>

Returns:

an Iterator.
