Class GraphXMLExport

java.lang.Object

org.wandora.application.tools.AbstractWandoraTool

org.wandora.application.tools.exporters.AbstractExportTool

org.wandora.application.tools.exporters.GraphXMLExport

All Implemented Interfaces:

java.io.Serializable, java.lang.Runnable, WandoraTool, WandoraToolLogger, TopicMapLogger

public class GraphXMLExport
extends AbstractExportTool
implements WandoraTool

Exports selected topic map in Wandora as GraphXML file. GraphXML format files can be used with HyperGraph application for example. See http://hypergraph.sourceforge.net/simple_graphs.html for more info about GraphXML format.

Note that the GraphXML file format is rather simple and can't represent all details of Topic Maps. Export converts all topics and occurrences as graph nodes. All associations are exported as graph edges. If association has more than two players, an itermediator node is added to link all players.

Export doesn't convert subject locators, subject identifiers, different variant names, association roles, occurrence scopes etc.

Method Detail

getIcon

public javax.swing.Icon getIcon()

Description copied from class: AbstractWandoraTool

All tools may have identifying graphic icon used within tool GUI elements. getIcon should return Icon object of the tool.

Specified by:

getIcon in interface WandoraTool

Overrides:

getIcon in class AbstractExportTool

Returns:

icon for the tool.

requiresRefresh

public boolean requiresRefresh()

Description copied from class: AbstractWandoraTool

If any visible topic has been changed during tool execution GUI is automatically refreshed. If tool doesn't change topics but GUI still requires refresh, tool should override this method and return true.

For example tools that alter the GUI but change no topics should return true.

Specified by:

requiresRefresh in interface WandoraTool

Overrides:

requiresRefresh in class AbstractWandoraTool

Returns:

true if Wandora application should refresh user interface.

isConfigurable

public boolean isConfigurable()

Description copied from class: AbstractWandoraTool

Whether this tool is configurable. Configurable tools will provide an interface to configure themselves. To make a configurable tool you will need to:

• Implement isConfigurable method and return true there.
• Implement initialize method to initialize the tool with saved options.
• Implement configure method to provide the user interface for configuration and then save the new options.
• Implement writeOptions method to save the current options.

Specified by:

isConfigurable in interface WandoraTool

Overrides:

isConfigurable in class AbstractWandoraTool

Returns:

true if the tool is configurable.
