public final class Nodes extends Object
Implements a list of nodes for traversal purposes. Changes to the document from which this list was generated are not reflected in this list, nor are changes to the list reflected in the document. Changes to the individual
Node
objects in the list and the document are reflected in the other one.There is no requirement that the list not contain duplicates, or that all the members come from the same document. It is simply a list of nodes.

- the number of nodes in the list
-
get
public Node get(int index)
Returns the indexth node in the list. The first node has index 0. The last node has index
size()-1
.- Parameters:
index
- the node to return- Returns:
- the node at the specified position
- Throws:
IndexOutOfBoundsException
- ifindex
is negative or greater than or equal to the size of the list
-

is negative or strictly greater than the size of the listNullPointerException
- ifnode
is null
