Constructor Detail

MultiNode

public MultiNode()

Create a new leaf node with multiple children.

MultiNode

public MultiNode(java.lang.Object weight,
                 int max_children)

Create a new leaf node with multiple children with the weight and number of children as specified by the parameter

Method Detail

append

public void append(MultiNode b)
            throws OverflowException

Adds a new node

getChildCount

public int getChildCount()

setChildCount

public void setChildCount()

setPosition

public void setPosition(int x,
                        int y,
                        int width,
                        int height)

Start at a node and set the positions for the sub-tree elements dx is the distance between two child nodes in x direction dy is the distance between the parent and the child node in y direction

Overrides:

setPosition in class BasicNode

drawEdge

public void drawEdge(java.awt.Graphics g,
                     MultiNode child)

Draw the edge from node to children

draw

public void draw(java.awt.Graphics g,
                 MultiNode sentinel)

Draws the corresponding node and the edge to the child nodes

move

public void move(int x,
                 int y)

Move the node and all its branches based on the parameters.

Overrides:

move in class BasicNode

Parameters:

x - The horizontal destination position of this node.

y - The vertical destination position of this node.

displace

public void displace(int dx,
                     int dy)

Move the tree starting with node dx pixels to the right and dy pixels down.

Overrides:

displace in class BasicNode

Parameters:

node - The root node of the tree to be moved.

dx - The change in x direction.

dy - The change in y direction.

drawSubTree

public void drawSubTree(java.awt.Graphics g)

                 throws OverflowException

Substitute the setLeft and setRight method

getTreeNode

public MultiNode getTreeNode(int index)

Get a specific node .. returns null if index is illegal or the node does not exist

isLeaf

public boolean isLeaf()

Check if this node is a leaf node.

Overrides:

isLeaf in class BasicNode

Returns:

true if the node is a leaf node; false otherwise.
