  net.guha.util.cdk.Node<T>

public class Node<T>
extends java.lang.Object

Represents a node of the Tree class. The Node is also a container, and can be thought of as instrumentation to determine the location of the type T in the Tree.

T	data

Constructor Summary

Node()
Default ctor.

Node(T data)
Convenience ctor to create a Node with an instance of T.

Method Summary

void	addChild(Node<T> child) Adds a child to the list of children for this Node.
java.util.List<Node<T>>	getChildren() Return the children of Node.
T	getData()
int	getNumberOfChildren() Returns the number of immediate children of this Node.
void	insertChildAt(int index, Node<T> child) Inserts a Node at the specified position in the child list.
void	removeChildAt(int index) Remove the Node element at index index of the List>.
void	setChildren(java.util.List<Node<T>> children) Sets the children of a Node object.

Default ctor.

Node

public Node(T data)

Convenience ctor to create a Node with an instance of T.

Parameters:

data - an instance of T.

Method Detail

getChildren

public java.util.List<Node<T>> getChildren()

Return the children of Node. The Tree is represented by a single root Node whose children are represented by a List>. Each of these Node elements in the List can have children. The getChildren() method will return the children of a Node.

Returns:

the children of Node

setChildren

public void setChildren(java.util.List<Node<T>> children)

Sets the children of a Node object. See docs for getChildren() for more information.

Parameters:

children - the List> to set.

getNumberOfChildren

public int getNumberOfChildren()

Returns the number of immediate children of this Node.

Returns:

the number of immediate children.

addChild

public void addChild(Node<T> child)

Adds a child to the list of children for this Node. The addition of the first child will create a new List>.

Parameters:

child - a Node object to set.

insertChildAt

public void insertChildAt(int index,
                          Node<T> child)
                   throws java.lang.IndexOutOfBoundsException

Inserts a Node at the specified position in the child list. Will * throw an ArrayIndexOutOfBoundsException if the index does not exist.

Parameters:

index - the position to insert at.

child - the Node object to insert.

Throws:

java.lang.IndexOutOfBoundsException - if thrown.

removeChildAt

public void removeChildAt(int index)
                   throws java.lang.IndexOutOfBoundsException

Remove the Node element at index index of the List>.

Parameters:

index - the index of the element to delete.

Throws:

java.lang.IndexOutOfBoundsException - if thrown.

getData

public T getData()

setData

public void setData(T data)

toString
