question: private void createNewStatusSet ( ) { if ( log . isDebugEnabled ( ) ) { log . debug ( "createNewFamily: type= \"" + _type + "\", family= \"" + _family + "\" key= " + _key ) ; } HashMap < String , NamedIcon > iconMap = ItemPanel . makeNewIconMap ( "Turnout" ) ; ItemPalette . addLevel4FamilyMap ( _type , _parent . _family , _key , iconMap ) ; addFamilySet ( _parent . _family , iconMap , _key ) ; dispose ( ) ; }
