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

context - context of this PlugIn

Throws:

Exception - if an Exception occurs during the run

transferAttributes

public FeatureDataset transferAttributes(FeatureSchema fs,
                                         org.locationtech.jts.index.quadtree.Quadtree treeWithFeatures,
