Class ReshapeOperation

java.lang.Object
  net.refractions.udig.catalog.ui.operation.ReshapeOperation

public class ReshapeOperation
extends java.lang.Object

This class pops up a dialog and asks the user to fiddle with the expressions used to create a new temporary layer.

While the Dialog may be simple; this is a reasonable example at how to hack at an operation that processes data in a way that does not force all the data into memory.

However the createTemporaryResource method may use a MemoryDataStore depending on how your environment is configured.

I would like to see this class changed to be a wizard, with an option to export directly to shapefile (rather than a temporary resource ).
