Method Detail

getAppletInfo

public String getAppletInfo()

Overrides:

getAppletInfo in class Applet

init

public void init()

Overrides:

init in class Applet

getDefaultControlsVisible

public boolean getDefaultControlsVisible()

Description copied from interface: VizFrontEndIF

Are the controls to this front end visible by default?

Specified by:

getDefaultControlsVisible in interface VizFrontEndIF

Returns:

true if the controls should be visible by default, false otherwise.

getDefaultLocality

public int getDefaultLocality()

resolve

public String resolve(String base)
               throws MalformedURLException

INTERNAL: Resolves the URI relative to the applet's codebase URI.

Throws:

MalformedURLException

getResolvedParameter

public String getResolvedParameter(String param)

getMaxLocality

public int getMaxLocality()

getEnabledItemIds

public ParsedMenuFile getEnabledItemIds()

Process the menu file and get the enabled item ids from it.

getTopicMap

public TopicMapIF getTopicMap()

Description copied from interface: VizFrontEndIF

Return the topic map that this front end is displaying

Specified by:

getTopicMap in interface VizFrontEndIF

Returns:

current topic map

mapPreLoaded

public boolean mapPreLoaded()

Description copied from interface: VizFrontEndIF

Return true if this front end loads the topic map before generating any display, false if the display is generated before the map is loaded. In general, front ends that do not allow for the map to be changed (servlets, etc) will pass in a single map, while the desktop application allows you to load and change the map.

Specified by:

mapPreLoaded in interface VizFrontEndIF

Returns:

true if the map is loaded before the display is initialized, false otherwise

setNewTypeColor

public void setNewTypeColor(TopicIF type,
                            Color c)

Description copied from interface: VizFrontEndIF

set the color on a specific topic type

Specified by:

setNewTypeColor in interface VizFrontEndIF

configureFilterMenus

public void configureFilterMenus()

Description copied from interface: VizFrontEndIF

Set up the menus to control the filters

Specified by:

configureFilterMenus in interface VizFrontEndIF

useGeneralConfig

public boolean useGeneralConfig()

Description copied from interface: VizFrontEndIF

Does this front end use the general configuration. Some front ends (desktop) use the VizGeneralConfigurationManager, while others exclusively use the VizTopicMapConfigurationManager.

Specified by:

useGeneralConfig in interface VizFrontEndIF

Returns:

true if VizGeneralConfigurationManager is supported, false otherwise

getWallpaper

public String getWallpaper()

Description copied from interface: VizFrontEndIF

Get the url of the wallpaper for the background.

Specified by:

getWallpaper in interface VizFrontEndIF

Returns:

URL of the wallpaper file, null if no wallpaper

getConfigURL

public String getConfigURL()

Description copied from interface: VizFrontEndIF

Get the URL of the config file

Specified by:

getConfigURL in interface VizFrontEndIF

Returns:

URL of the config file, null if the default is to be used

getTypesConfigFrame

public TypesConfigFrame getTypesConfigFrame(VizController controller,
                                            boolean isTopicConfig)

Description copied from interface: VizFrontEndIF

Returns the configuration frame that can be used to set colors for either Topics or Associations

Specified by:

getTypesConfigFrame in interface VizFrontEndIF

isTopicConfig - - is this a Topic or Association configuration frame

Returns:

configuration frame - if True return TopicConfigurationFrame, else return AssociationConfigFrame

getContext

public ApplicationContextIF getContext()

Description copied from interface: VizFrontEndIF

Get the appropriate ApplicationContextIF for this front end.

Specified by:

getContext in interface VizFrontEndIF

Returns:

ApplicationContextIF for this front end
