Constructor Detail

### EditorSource

    public EditorSource()

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
