本文整理了Java中org.jruby.Ruby.evalScriptlet方法的一些代码示例，展示了Ruby.evalScriptlet的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Ruby.evalScriptlet方法的具体详情如下：
包路径：org.jruby.Ruby
类名称：Ruby
方法名：evalScriptlet

Ruby.evalScriptlet介绍

[英]Evaluates a script under the current scope (perhaps the top-level scope) and returns the result (generally the last value calculated). This version goes straight into the interpreter, bypassing compilation and runtime preparation typical to normal script runs.
[中]在当前作用域（可能是顶级作用域）下计算脚本，并返回结果（通常是最后计算的值）。这个版本直接进入解释器，绕过编译和运行时准备，这是正常脚本运行的典型情况。

代码示例
