Sets geomentryMethodNames variable using getGeometryMethodNames function.

Method Detail

execute

public boolean execute(PlugInContext context)
                throws Exception

Description copied from interface: PlugIn

Performs the action for this plugin. For threaded plugins with dialogs, this method contains the code to invoke the dialog. If the user cancels the dialog, this method should return false to prevent the run method from being called.

Specified by:

execute in interface PlugIn

Overrides:

execute in class AbstractPlugIn

Returns:

true if the action completed, false if it was aborted. Used by ThreadedPlugIns to indicate that their #run method needn't be called next.

Throws:

Exception - if a problem occurs during plug-in execution

run

public void run(TaskMonitor monitor,
                PlugInContext context)
         throws Exception

Description copied from interface: ThreadedPlugIn

Runs the task. This method will be executed in a separate thread, so that the GUI remains responsive (but only partially so, as a modal progress dialog will be in the way). Don't call GUI classes in this method as it is not executed on the GUI thread.

Specified by:

run in interface ThreadedPlugIn

Parameters:

monitor - context to which this task can report its progress and check whether a party has requested its cancellation

Throws:

Exception
