All Implemented Interfaces:

javax.accessibility.Accessible, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable

public class SpyApplet

extends ParameterApplet

The actual Locator-Applet (this must be called in the applet-tag). Handles all the parameters, puts everything up and is responsible for starting and stopping of the Threads. For a quick overview of all involved classes, see the UML Class Diagram. Documentation on how to use this applet in a website is available here.

Constructor Detail

SpyApplet

public SpyApplet()

Method Detail

init

public void init()

Initializes the Applet. The Persons are created with the colors defined by the parameters, then an initial position file is loaded synchronously. Finally an Animator and SpyCanvas are constructed.

Overrides:

init in class ParameterApplet

start

public void start()

When called the first time, the Animator and the PositionLoader are started. If that had already happened before, they are only resumed.

Overrides:

start in class java.applet.Applet

stop

public void stop()

Suspends Animator and PositionLoader. Note that the original Thread methods suspend() and resume() are not used since they are quite unsafe.

Overrides:

stop in class java.applet.Applet

destroy

public void destroy()

Finishes the Threads and frees image resources.

Overrides:

destroy in class java.applet.Applet

getAppletInfo

public java.lang.String getAppletInfo()

Shows information about this applet.

Overrides:

getAppletInfo in class ParameterApplet

Returns:

Component.getName()

getParameterInfo

public java.lang.String[][] getParameterInfo()

Shows which parameters are allowed. These parameters are always available, for more parameters override this and handleParams().

Overrides:

getParameterInfo in class ParameterApplet

Returns:

foreground -- RGB-Value -- foreground color, e.g. 0 0 0
background -- RGB-Value -- background color, e.g. 255 255 255
person_x_color -- RGB-Value -- the color of person x
person_x_id -- String -- the id of person x, as used in the position file
positionfile -- String -- the file with the position information including path from docbase
pathareafile -- String -- the file with PathAreas including path from docbase
areafile -- String -- the file with Areas including path from docbase
housebgimg -- String -- an image - gif or jpg - including its path from the document base
fps -- integer -- the framerate of the animation in frames per second
