question: adds an topological node to this graph concode_field_sep List<TopologicalLink> linkList concode_elem_sep List<TopologicalNode> nodeList concode_field_sep int getNumberOfNodes concode_elem_sep Iterator<TopologicalNode> getNodeIterator concode_elem_sep int getNumberOfLinks concode_elem_sep String toString concode_elem_sep void addLink concode_elem_sep Iterator<TopologicalLink> getLinkIterator
target: void function ( TopologicalNode arg0 ) { nodeList . add ( arg0 ) ; }
