  31  * Standard workbench wizard for exporting resources from the workspace to the
  32  * local file system.
  33  * <p>
  34  * This class may be instantiated and used without further configuration; this
  35  * class is not intended to be subclassed.

  37  * <p>
  38  * Example:
  39  *
  40  * <pre>
  41  * IWizard wizard = new ObfuscatorExportWizard();
  42  * wizard.init(workbench, selection);
  43  * WizardDialog dialog = new WizardDialog(shell, wizard);
  44  * dialog.open();
  45  * </pre>
  46  *
  47  * During the call to <code>open</code>, the wizard dialog is presented to
  48  * the user. When the user hits Finish, the user-selected workspace resources
  49  * are exported to the user-specified location in the local file system, the
  50  * dialog closes, and the call to <code>open</code> returns.
