本文整理了Java中com.squareup.javapoet.ClassName类的一些代码示例，展示了ClassName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。ClassName类的具体详情如下：
包路径：com.squareup.javapoet.ClassName
类名称：ClassName

ClassName介绍

[英]A fully-qualified class name for top-level and member classes.
[中]顶级类和成员类的完全限定类名。
