Question

好的，我的问题是如何将包org.antlr.stringtemplate.StringTemplate toDOT（Tree tree）中的StringTemplate toDot（Tree tree）更改为或者以其他方式更改

我的代码就像这样

DOTTreeGenerator gen = new DOTTreeGenerator();
StringTemplate st = gen.toDOT(tree);

所以，它生成.dot文件，但我想改变模板的大小

digraph {
ordering=out;
 ranksep=.4;
 node [shape=plaintext, fixedsize=true, fontsize=11, fontname="Courier",
    width=.25, height=.25];
 edge [arrowsize=.5]
  n0 [label=""];
  n1 [label="ANNOTATION_LIST"];
  n2 [label="package"];
  n2 [label="package"];
  n3 [label="Buat_Test_file"];
  n4 [label=";"];
  n5 [label="MODIFIER_LIST"];
  n5 [label="MODIFIER_LIST"];
  n6 [label="public"];
  n7 [label="class"];
 n7 [label="class"];
 n5 [label="MODIFIER_LIST"];
 n5 [label="MODIFIER_LIST"];
 n6 [label="public"];
 n8 [label="Gilang"];
n9 [label="CLASS_TOP_LEVEL_SCOPE"];

n0 -> n1 // "" -> "ANNOTATION_LIST"
n0 -> n2 // "" -> "package"
n2 -> n3 // "package" -> "Buat_Test_file"
n2 -> n4 // "package" -> ";"
n0 -> n5 // "" -> "MODIFIER_LIST"
n5 -> n6 // "MODIFIER_LIST" -> "public"
n0 -> n7 // "" -> "class"
n7 -> n5 // "class" -> "MODIFIER_LIST"
n5 -> n6 // "MODIFIER_LIST" -> "public"
n7 -> n8 // "class" -> "Gilang"
n7 -> n9 // "class" -> "CLASS_TOP_LEVEL_SCOPE"
}

我想改变宽度，高度和边缘。

非常感谢...

负责输出的StringTemplate是public static和DOTTreeGenerator内的public class DOTTreeGenerator { public static StringTemplate _treeST = new StringTemplate( "digraph {\n\n" + "\tordering=out;\n" + "\tranksep=.4;\n" + "\tbgcolor=\"lightgrey\"; node [shape=box, fixedsize=false, fontsize=12, fontname=\"Helvetica-bold\", fontcolor=\"blue\"\n" + "\t\twidth=.25, height=.25, color=\"black\", fillcolor=\"white\", style=\"filled, solid, bold\"];\n" + "\tedge [arrowsize=.5, color=\"black\", style=\"bold\"]\n\n" + " $nodes$\n" + " $edges$\n" + "}\n"); ... }：

double width = 0.5;
double height = 0.5;
Strign edge = "[arrowsize=.7, color=\"red\", style=\"bold\"]";

DOTTreeGenerator._treeST = new StringTemplate(
                "digraph {\n\n" +
                "\tordering=out;\n" +
                "\tranksep=.4;\n" +
                "\tbgcolor=\"lightgrey\"; node [shape=box, fixedsize=false, fontsize=12, fontname=\"Helvetica-bold\", fontcolor=\"blue\"\n" +
                "\t\twidth=" + width + ", height=" + height + ", color=\"black\", fillcolor=\"white\", style=\"filled, solid, bold\"];\n" +
                "\tedge " + edge + "\n\n" +
                "  $nodes$\n" +
                "  $edges$\n" +
                "}\n"); 

DOTTreeGenerator gen = new DOTTreeGenerator();
StringTemplate st = gen.toDOT(...);
...

换句话说：只需在打印树之前更改模板：
