question: returns true if the specified object is registered with the dataset as a listener . most applications wo n't need to call this method , it exists mainly for use by unit testing code . concode_field_sep EventListenerList listenerList concode_elem_sep long serialVersionUID concode_elem_sep DatasetGroup group concode_field_sep void setGroup concode_elem_sep void removeChangeListener concode_elem_sep void fireDatasetChanged concode_elem_sep void validateObject concode_elem_sep void writeObject concode_elem_sep DatasetGroup getGroup concode_elem_sep void notifyListeners concode_elem_sep Object clone concode_elem_sep void addChangeListener concode_elem_sep void readObject
target: boolean function ( EventListener arg0 ) { List loc0 = Arrays . asList ( this . listenerList . getListenerList ( ) ) ; return loc0 . contains ( arg0 ) ; }
