public class JRoofView
extends AbstractDisplayable

A graphical display of the current state of the roof. Five different positions of the roof are recognized, depending on the status of the limit switches and the X-switches. Additionally to these switches, the state of the roof locking mechanism can be queried. A typical roof view looks like

The typical use of a roof view will be within an other applications, notably an error event listener that can pipe received status messages to the RoofInfo and further to the roof view class to obtain an accurate view of the current roof state.

Note that the roof-view class does not care about the format of the status message, it must be converted in an other application to the appropriate input format, see RoofInfo.

Constructor Detail

JRoofView

public JRoofView(Map info)

Constructs a new roof view instance. Nothing is displayed until the getRepresentation() method is called. The constructor takes care of initializing all images and parsing all offsets.

All properties required by the roof view class has defaults, so construction is successful even when called with an empty properties object.

Method Detail

init

public void init()

The init method loads all images.

Specified by:

init in interface Initializable

Overrides:

init in class PropertyContainer

loadGreenRed

private Image[] loadGreenRed(String filename)

Loads two images, a green and a red version. The filename provided is augmented right before the .ext-extension with the file name parts found in KEY_GREEN and KEY_RED. The image with the index zero is always the green pic.

Because this method uses the ImageIcon class, it blocks until the images are fully loaded.

getRepresentation

public Component getRepresentation()

Returns a panel to show the current status of the roof. The returned panel does not show anything, but has its size set to the correct dimension. Drawing onto the component is only possible after it is displayed. The showRoof(stella.roof.RoofInfo[]) method does this things.

showRoof

public void showRoof(RoofInfo[] roofinfo)

Takes an array of roof info objects to deduce the status of the roof to draw. Even indices are left-handed roofs, odd indices right-handed roofs. The display panel is updated if it is showing.

showLeftRoof

private void showLeftRoof(Trigger[] info)

Draws the image of a left-handed roof according to the roof info settings. This method directly sets the images needed by the JRoofView.JRoofCanvas class for correctly drawing the roof. The roof canvas is not told to repaint, this should be done in the calling routine.

showRightRoof

private void showRightRoof(Trigger[] info)

Draws the image of a left-handed roof according to the roof info settings. This method directly sets the images needed by the JRoofView.JRoofCanvas class for correctly drawing the roof. The roof canvas is not told to repaint, this should be done in the calling routine.

getSpeedBlink

private int getSpeedBlink(Trigger[] info)

Get the blink frequency of the speed indicator. Zero means no blink.

getNorthBoltBlink

private int getNorthBoltBlink(Trigger[] info)

Get the blink frequency of the north bolt. Zero means no blink.

getSouthBoltBlink

private int getSouthBoltBlink(Trigger[] info)

Get the blink frequency of the south bolt. Zero means no blink.

placeLeftRoof

private void placeLeftRoof(int xoff,
                           Image lrti,
                           Image lrsi,
