本文整理了Java中org.jruby.RubyHash类的一些代码示例，展示了RubyHash类的具体用法。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。RubyHash类的具体详情如下：
包路径：org.jruby.RubyHash
类名称：RubyHash

RubyHash介绍

[英]Implementation of the Hash class. Concurrency: no synchronization is required among readers, but all users must synchronize externally with writers.
[中]哈希类的实现。并发性：读卡器之间不需要同步，但所有用户都必须在外部与写卡器同步。
