Deprecated. Use DataEditorSupport instead

public class EditorSupport
extends OpenSupport
implements EditorCookie.Observable, OpenCookie, CloseCookie, PrintCookie

Support for associating an editor and a Swing Document to a data object. Can be assigned as a cookie to any editable data object. Then this data object will be capable of being opened in an editor, and there will be ways of retrieving and acting upon the Swing document which is editing it.
