question: sets reference to the graph owning this node . concode_field_sep DataT data concode_elem_sep List<String> children concode_elem_sep String key concode_elem_sep Graph<DataT,NodeT> ownerGraph concode_field_sep Graph<DataT,NodeT> owner concode_elem_sep DataT data concode_elem_sep List<String> children concode_elem_sep boolean hasChildren concode_elem_sep void addChild concode_elem_sep String key
target: void function ( Graph < DataT , NodeT > arg0 ) { if ( this . ownerGraph != null ) { throw new RuntimeException ( "srini_string" ) ; } this . ownerGraph = arg0 ; }
