33  * Standard workbench wizard for exporting resources from the workspace
34  * to the local file system.
35  * <p>
36  * This class may be instantiated and used without further configuration;
37  * this class is not intended to be subclassed.
38  * </p>
39  * <p>
40  * Example:
41  * <pre>
42  * IWizard wizard = new FileSystemExportWizard();
43  * wizard.init(workbench, selection);
44  * WizardDialog dialog = new WizardDialog(shell, wizard);
45  * dialog.open();
46  * </pre>
47  * During the call to <code>open</code>, the wizard dialog is presented to the
48  * user. When the user hits Finish, the user-selected workspace resources
49  * are exported to the user-specified location in the local file system,
50  * the dialog closes, and the call to <code>open</code> returns.
51  * </p>
