英文:
Tinkerpop traversal to string
问题
从遍历中获取一个准备好供使用的Gremlin请求是否可能？就像JPA在调试级别记录日志一样。对于TinkerPop来说，调试输出会给出traversal.toString()，但是将其转换为请求很耗时。
英文:
Is it possible to get from a traversal a gremlin request ready to use ? As JPA do with the log in debug level. For tinkerpop the debug give the traversal.toString() which is time consuming to transform in a request.

你可以使用 Apache TinkerPop 中的 GroovyTranslator 类将遍历转换回文本形式。
如果你有一个定义如下的遍历：
Traversal t =
g.V().has("airport","region","US-TX").
local(values("code","city")).
fold();
你可以使用以下代码将其转换为文本字符串：
String query;
query = GroovyTranslator.of("g").
translate(t.asAdmin().getBytecode());
System.out.println("\nResults from GroovyTranslator on a traversal");
System.out.println(query);
这里还有更多的示例：

英文:
You can translate a traversal back into a textual form using the GroovyTranslator class from Apache TinkerPop.
If you had a traversal defined as follows
Traversal t =
g.V().has("airport","region","US-TX").
local(values("code","city").
fold());
You can convert that back to a text string using
String query;
query = GroovyTranslator.of("g").
translate(t.asAdmin().getBytecode());
System.out.println("\nResults from GroovyTranslator on a traversal");
System.out.println(query);
