Class Value2DDisplay

java.lang.Object
  uchicago.src.sim.gui.Display2D
      uchicago.src.sim.gui.Value2DDisplay

All Implemented Interfaces:

Displayable, Probeable

public class Value2DDisplay
extends Display2D
implements Probeable

Displays 2d arrays of values (Integers or ints). As a Displayable this class iterates through a Discrete2DSpace, turns the integers into colors according to a ColorMap, and draws these colors in the appropriate cells.

Constructor Summary

Value2DDisplay(Discrete2DSpace grid, ColorMap map)
Creates a Value2DDisplay to display the specified Discrete2DSpace using the specified ColorMap.

Method Summary

void	drawDisplay(SimGraphics g) Draws the Discrete2DSpace converting the Numbers contained therein to Colors according to the ColorMap specified in the constructor
java.util.ArrayList	getDisplayableInfo() Gets a list of the DisplayInfo objects associated with this Object2DDisplay.
java.util.ArrayList	getObjectsAt(int x, int y) Gets an ArrayList of Objects at an x, y screen (pixel) coordinate.
boolean	isZeroTransparent() Returns whether a zero value in space drawn by this grid is transparent or drawn according to the color map.
void	setDisplayMapping(int m, int c) Linear transform of states (doubles, floats, integers etc.) to colors for drawing. color = state / m + c
void	setMoveableXY(Moveable moveable, int x, int y) Sets the new coordinates for specified moveable.
void	setZeroTransparent(boolean val) Sets whether or not a zero value in space drawn by this grid is transparent or drawn according to the color map.
void	viewEventPerformed(ViewEvent evt) Invoked when a viewEvent for this display is fired by the DisplaySurface.

Constructor Detail

Value2DDisplay

public Value2DDisplay(Discrete2DSpace grid,
                      ColorMap map)

Creates a Value2DDisplay to display the specified Discrete2DSpace using the specified ColorMap.

Method Detail

setDisplayMapping

public void setDisplayMapping(int m,
                              int c)

Linear transform of states (doubles, floats, integers etc.) to colors for drawing. color = state / m + c

setZeroTransparent

public void setZeroTransparent(boolean val)

Sets whether or not a zero value in space drawn by this grid is transparent or drawn according to the color map. Default is to draw according to the color map.

Parameters:

val - if true, zero value will be drawn as transparent, otherwise the value in the color map is drawn.

isZeroTransparent

public boolean isZeroTransparent()

Returns whether a zero value in space drawn by this grid is transparent or drawn according to the color map.

drawDisplay

public void drawDisplay(SimGraphics g)

Draws the Discrete2DSpace converting the Numbers contained therein to Colors according to the ColorMap specified in the constructor

Specified by:

drawDisplay in interface Displayable

Specified by:

drawDisplay in class Display2D

getDisplayableInfo

public java.util.ArrayList getDisplayableInfo()

Gets a list of the DisplayInfo objects associated with this Object2DDisplay.

Specified by:

getDisplayableInfo in interface Displayable

DisplayInfo

viewEventPerformed

public void viewEventPerformed(ViewEvent evt)

Invoked when a viewEvent for this display is fired by the DisplaySurface.

Specified by:

viewEventPerformed in interface Displayable

getObjectsAt

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

Gets an ArrayList of Objects at an x, y screen (pixel) coordinate. Implements the probeable interface.

Specified by:

getObjectsAt in interface Probeable

Parameters:

x - the x screen coordinate.

y - the y screen coordinate.

Returns:

the object at the x, y coordinate.

setMoveableXY

public void setMoveableXY(Moveable moveable,
                          int x,
                          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:

setMoveableXY in interface Probeable

Parameters:

moveable - the moveable whose coordinates are changed

x - the x coordinate in pixels

y - the y coordinate in pixels
