Class Network2DDisplay

java.lang.Object
  uchicago.src.sim.gui.Network2DDisplay

All Implemented Interfaces:

Displayable, Probeable, Zoomable

public class Network2DDisplay
extends java.lang.Object
implements Displayable, Probeable, Zoomable

Displays nodes and links that inhabit a VectorSpace, that is, nodes (and their links) that do not inhabit a grid. This expects to be drawing a VectorSpace of DrawableNonGridNodes or a List of DrawableNonGridNodes. Note that for efficiency this only draws a Node's out edges (which must be some other Node's in edge and so they all get drawn). It is important then that any edge that is being drawn be added to some Nodes list of out edges. In addition, these edges must implement DrawableEdge in order to be drawn.

Constructor Detail

Network2DDisplay

public Network2DDisplay(VectorSpace space,
                        int width,
                        int height)

Creates a Network2DDisplay of the specified width and height for displaying the DrawableNonGridNodes and DrawableEdges in the specified space.

Parameters:

space - the space containing the DrawableNonGridNodes to display

width - the width of the display in pixels

height - the height of the display in pixels

Network2DDisplay

public Network2DDisplay(java.util.List list,
                        int width,
                        int height)

Creates a Network2DDisplay of the specified width and height for displaying the DrawableNonGridNodes in the list.

Parameters:

list - the list containing the DrawableNonGridNodes to display

width - the width of the display in pixels

height - the height of the display in pixels

Network2DDisplay

public Network2DDisplay(GraphLayout layout)

Creates a Network2DDisplay using the specified GraphLayout.

Parameters:

layout - the GraphLayout for this Network2DDisplay.

Method Detail

getDrawEdgesFirst

public boolean getDrawEdgesFirst()

Gets whether or not this draws the edges first and then the nodes over them. Default value is false.

Returns:

if true this draws the edges first then the nodes over them

setDrawEdgesFirst

public void setDrawEdgesFirst(boolean drawEdgesFirst)

Sets whether or not this draws the edges first and then the nodes over them. Default value is false.

Parameters:

drawEdgesFirst - whether or not this draws edges first then nodes

getSize

public java.awt.Dimension getSize()

Gets the size of this VectorDisplay.

Specified by:

getSize in interface Displayable

setLinksVisible

public void setLinksVisible(boolean isVisible)

Shows or hides links depending on the value of parameter isVisible.

Parameters:

isVisible - if true, shows the links, otherwise hide links

setNodesVisible

public void setNodesVisible(boolean isVisible)

Shows or hids nodes depending on the value of the parameter isVisible.

Parameters:

isVisible - if true, shows the nodes, otherwise hide nodes

drawDisplay

public void drawDisplay(SimGraphics g)

Draws this display

Specified by:

drawDisplay in interface Displayable

getDisplayableInfo

public java.util.ArrayList getDisplayableInfo()

Gets the DisplayableInfo

Specified by:

getDisplayableInfo in interface Displayable

DisplayInfo

getObjectsAt

public java.util.ArrayList getObjectsAt(int x,
                                        int y)

Gets a list of the objects that contain the specified screen coordinate.

Specified by:

getObjectsAt in interface Probeable

Parameters:

x - the x coordinate

y - the y coordinate

Returns:

the object at the x, y coordinate.

setMoveableXY

public void setMoveableXY(Moveable moveable,

                          int y)

Sets the new coordinates for specified moveable. This goes through probeable as some translation between screen pixel coordinates and the simulation coordinates may be necessary.

Specified by:
