prajna.viz.display.AbstractGraphDisplay<N,E>

prajna.viz.display.MatrixGraphDisplay<N,E>

Type Parameters:

N - The node class for the graph

E - The edge class for the graph

All Implemented Interfaces:

java.awt.image.ImageObserver, java.awt.ItemSelectable, java.awt.MenuContainer, java.io.Serializable, GraphDisplay<N,E>

public class MatrixGraphDisplay<N,E>
extends AbstractGraphDisplay<N,E>

Graph display showing the incidence matrix for the graph. This display renders the graph in a square grid, with each row or column represnting a node. The edges are represented in the matrix as cells; nodes are represented along the diagonal of the matrix. The default component for rendering the cells is a JButton, though this can be set to another component.

Constructor Detail

MatrixGraphDisplay

public MatrixGraphDisplay()

Build a matrix graph display with an empty graph

Method Detail

getEdgeAt

public E getEdgeAt(java.awt.Point point)

Returns the edge located at the point. If the selected point is contained in one of the cells corresponding to an edge, the corresponding edge is returned.

Specified by:

getEdgeAt in class AbstractGraphDisplay<N,E>

Parameters:

point - the point in the canvas to pick for edges.

Returns:

the edge represented at the point

getNodeAt

public N getNodeAt(java.awt.Point point)

Returns the node located at the point. If the selected point is contained in one of the cells along the diagonal, the corresponding node is returned.

Specified by:

getNodeAt in class AbstractGraphDisplay<N,E>

Parameters:

point - the point in the canvas to pick for nodes.

Returns:

the node represented at the point

isShowLabels

public boolean isShowLabels()

Returns whether the labels are displayed for the matrix display

Returns:

true if the labels are visible, false otherwise

redrawEdge

public void redrawEdge(E edge)

Redraws an individual edge.

Specified by:

redrawEdge in class AbstractGraphDisplay<N,E>

Parameters:

edge - the node to redraw

redrawNode

public void redrawNode(N node)

Redraws an individual node

Specified by:

redrawNode in class AbstractGraphDisplay<N,E>

Parameters:

node - the node to redraw

setComponentClass

public void setComponentClass(java.lang.Class<? extends java.awt.Component> cmpClass)

Set the component class used to display the cells of the matrix. If not set, a JButton will be used.

Parameters:

cmpClass - the component class to use for displaying the nodes and edges

setGraph

public void setGraph(Graph<N,E> graph)

Set the graph displayed by this graph display

Specified by:

setGraph in interface GraphDisplay<N,E>

Overrides:

setGraph in class AbstractGraphDisplay<N,E>

Parameters:

graph - the graph to display

setShowLabels

public void setShowLabels(boolean showFlag)

Set whether the node labels are displayed. If set to true (the default), labels are displayed at the top and left of the matrix.

Parameters:

showFlag - whether to display the labels

updateGraph

public void updateGraph()

Update the currently displayed graph. This call should be invoked when the graph's contents change, such as when new nodes are added.
