public class Object2DHexaDisplay
extends HexaDisplay2D

Title: 2D Hexagonal Spaces Description: 2D Hexagonal space library Copyright: Copyright (c) 2001 Company: Harvard University Displays a hexagonal layout of Discrete2DSpaces and the objects contained within them. Implements probeable so that the objects within the Discrete2DSpace can be probed. All the objects within the space are expected to have implemented Drawable. Objects are displayed on a hexagonal grid.

Constructor Summary

Object2DHexaDisplay(Discrete2DSpace hexagrid)
Creates an Object2DHexaDisplay for displaying the specified Discrete2DSpace.

Method Summary

void	drawDisplay(SimGraphics g) Draws the contained space, either by iterating over the entire space and calling draw(SimGraphics g) on the Drawables contained therein, or by iterating through a list of Drawables and calling draw(SimGraphics g) on them.
java.util.ArrayList	getObjectsAt(int x, int y) Gets the object at the specified screen coordinates for probing.
void	setObjectList(java.util.ArrayList objectList) Sets the list of objects to display.

Constructor Detail

Object2DHexaDisplay

public Object2DHexaDisplay(Discrete2DSpace hexagrid)

Creates an Object2DHexaDisplay for displaying the specified Discrete2DSpace.

Parameters:

hexagrid - the space to display

Method Detail

setObjectList

public void setObjectList(java.util.ArrayList objectList)

Sets the list of objects to display. If a space is sparsely populated then rather than iterating over the entire space looking for objects to draw, this Object2DDisplay can iterate only over the specified list and draw those objects. This list is expected to contain objects implementing the drawable interface.

Parameters:

objectList - the list of objects to draw

getObjectsAt

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

Gets the object at the specified screen coordinates for probing.

Parameters:

x - the x coordinate

y - the y coordinate

Returns:

the list of objects at x,y

drawDisplay

public void drawDisplay(SimGraphics g)

Draws the contained space, either by iterating over the entire space and calling draw(SimGraphics g) on the Drawables contained therein, or by iterating through a list of Drawables and calling draw(SimGraphics g) on them. This method should never by called directly by a user.

Specified by:

drawDisplay in interface Displayable

Specified by:

drawDisplay in class Display2D

Parameters:

g - the graphics context on which to draw
