It's pretty easy to add in the functionality anyway, if you really
want it:
import java.util.AbstractList;
import com.google.gwt.dom.client.Node;
import com.google.gwt.dom.client.NodeList;
/**
* An immutable list view of NodeList<T>
* @author thobel
*
*/
public class NodeListWrapper<T extends Node> extends AbstractList<T> {
private NodeList<T> nodeList;
public NodeListWrapper(NodeList<T> nodeList){
this.nodeList = nodeList;
}
@Override
public T get(int n) {
return nodeList.getItem(n);
}
@Override
public int size() {
return nodeList.getLength();
}
}
