public static void allEditors() {
   IWorkbenchWindow[] win = SamplePlugin.getDefault()
   .getWorkbench().getWorkbenchWindows();
   for (int i = 0; i < win.length; i++) {
       IWorkbenchPage[] pages = win[i].getPages();
       for (int j = 0; j < pages.length; j++) {
       IEditorReference[] editors = pages[j].getEditorReferences();
        for (int k = 0; k < editors.length; k++) {
        IEditorPart editor = editors[k].getEditor(true);
        if (editor instanceof MyEditor)
        //getText() is the metod in MyEditor.
        ((MyEditor)editor).getText();
       }
      }
    }
