Class Nodes
public final class Nodes
extends java.lang.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.
Nodes() -
Creates an empty node list.
|
Nodes(Node node) -
Creates a node list containing a single node.
|
void | append(Node node) -
Adds a node at the end of this list.
|
boolean | contains(Node node) -
Determines whether a node is contained in this list.
|
Node | get(int index) -
Returns the indexth node in the list.
|
void | insert(Node node, int index) -
Inserts a node at the indexth position in the list.
|
Node | remove(int index) -
Removes the indexthnode in the list.
|
int | size() -
Returns the number of nodes in the list.

Nodes
public Nodes()
Creates an empty node list.
Nodes
public Nodes(Node node)
Creates a node list containing a single node.
node
- the node to insert in the list
append
public void append(Node node)
Adds a node at the end of this list.
node
- the node to add to the list
contains
public boolean contains(Node node)
Determines whether a node is contained in this list.
node
- the node to search for
- true if this list contains the specified node;
false otherwise
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
.
index
- the node to return
- the node at the specified position
insert
public void insert(Node node,
int index)
Inserts a node at the indexth position in the list.
Subsequent nodes have their indexes increased by one.
node
- the node to insertindex
- the position at which to insert the node
remove
public Node remove(int index)
Removes the indexthnode in the list.
Subsequent nodes have their indexes reduced by one.
index
- the node to remove
- the node at the specified position
size
public int size()
Returns the number of nodes in the list.
This is guaranteed to be non-negative.
- the number of nodes in the list
