java - Graphviz 特殊字符

Question

有人可以指导我如何构建

MV-123-1.3.2-23423GF

使用 Graphviz API 的字符串类型？

它在之后为每个令牌创建单独的圆圈 -

    GraphViz gv = new GraphViz();
  gv.addln(gv.start_graph());
  gv.addln("1.0 -> MV-123-1.3.2-23423GF [color=red];");
  gv.addln("MV-123-1.3.2-23423GF  -> 1.2 [color=red];");
  gv.addln("1.2 -> 1.3 [color=red];");
  gv.addln("1.3 -> 2.0;");
  gv.addln("2.0 -> 3.0;");
  gv.addln("3.0 -> 3.1;");
  gv.addln("1.0 -> 2.0;");
  gv.addln("1.1 -> 1.3;");
  gv.addln("2.5 -> 2.6;");
  gv.addln("2.6 -> 3.0 [splines=false];");

问候

要将其保留为单个标记，它需要双引号。这些必须在java中作为转义字符插入：

gv.addln("1.0 -> \"MV-123-1.3.2-23423GF\" [color=red];");
