使用ScriptObjectMirror将数组结果从JavaScript转换为有用的东西 [英] Casting Array Result From JavaScript to Something Useful Using ScriptObjectMirror

问题描述

如果我有一个返回字符串数组的JS 函数，我应该如何将其强制转换为有用的类型(我在考虑Java数组还是Collection类)?我注意到返回类型始终是 ScriptObjectMirror ，它具有有趣的 to(Class<?> clazz)方法，但是我不确定它的用途.我已经检查了其他几个StackOverflow问题，但是没有一个有用的.你能举个例子吗?

If I have a JS function that returns an array of strings, how should I go about casting it to a useful type (I'm thinking either a Java array or Collection class)? I've noticed that the return type is always a ScriptObjectMirror which has an interesting to(Class<?> clazz) method, but I'm uncertain on it's use. I've checked several other StackOverflow questions, but none were useful. Can you show an example?

推荐答案

好，这对我有用:

ScriptObjectMirror result = (ScriptObjectMirror) function.invokeFunction("nameGen", 10);
        String[] strings = result.to(String[].class);
