→Operations 操作方式
* <code>set_vertex_value</code>(''G'', ''x'', ''v''): sets the value associated with the vertex ''x'' to ''v''.
* <code>set_vertex_value</code>(''G'', ''x'', ''v''): sets the value associated with the vertex ''x'' to ''v''.
* <code>adjacent</code>(" G "， " x "， " y "):检验顶点" x "到顶点" y "是否有边;
* <code>neighbors</code>(“G”，“x”):列出所有顶点“y”，使顶点“x”有一条边到顶点“y”;
* <code> add_vertex > < /代码(“G”、“x”):添加顶点“x”,如果它是不存在的;
* <code>remove_vertex</code>(" G "， " x "):删除顶点" x "(如果存在的话);
* <code>add_edge</code>(" G "， " x "， " y "):将顶点" x "的边添加到顶点" y "(如果不存在的话);
* <code>remove_edge</code>(" G "， " x "， " y "):将顶点" x "的边移到顶点" y "的边(如果存在的话);
* <code>get_vertex_value</code>(" G "， " x "):返回与顶点" x "相关的值;
* <code> set_vertex_value > </code>(“G”、“x”、“v”):设置顶点的值与“x”“v”。

* <code>set_edge_value</code>(''G'', ''x'', ''y'', ''v''): sets the value associated with the edge (''x'', ''y'') to ''v''.
* <code>set_edge_value</code>(''G'', ''x'', ''y'', ''v''): sets the value associated with the edge (''x'', ''y'') to ''v''.
* <code>get_edge_value</code>(''G'', ''x'', ''y''): 连接点 (''x'', ''y'')的返回值;
* <code>set_edge_value</code>(''G'', ''x'', ''y'', ''v''): 连接点(''x'', ''y'') 到 ''v''的设置值.
