  - ### Method Detail

    - #### create

          public abstract E create​(int index)

      Create a new Editor.
      Parameters:
        `index` - the position at which the new Editor should be displayed
      Returns:
        an `Editor` of type E

    - #### create

          public java.util.List<E> create​(int count,
                                          int index)

      Create multiple Editors. This method may be optionally overridden to provide a more efficient means of creating Editors in bulk.
      Parameters:
        `count` - the number of Editors desired
        `index` - the position at which the new Editors should be displayed
      Returns:
        a List of `Editor`s of type E

    - #### createEditorForTraversal

          public E createEditorForTraversal()

      Creates a temporary sub-Editor to use for traversal.

      For backwards compatibility with GWT 2.5.0 and earlier, the default implementation calls `create(0)` and `disposes` the editor right away.

      Returns:
        an `Editor` of type E
      See Also:
        `ListEditor.createEditorForTraversal()`, `EditorContext.traverseSyntheticCompositeEditor(com.google.gwt.editor.client.EditorVisitor)`

    - #### dispose

          public void dispose​(E subEditor)

      Called when an Editor no longer requires a sub-Editor. The default implementation is a no-op.
      Parameters:
        `subEditor` - an `Editor` of type E

    - #### setIndex

          public void setIndex​(E editor,
                               int index)

      Re-order a sub-Editor. The default implementation is a no-op.
      Parameters:
        `editor` - an `Editor` of type E
        `index` - the index of the Editor
