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

JType介绍

[英]A representation of a type in codeModel. A type is always either primitive ( JPrimitiveType) or a reference type ( JClass).
[中]代码模型中类型的表示形式。类型始终是基元（JPrimitiveType）或引用类型（JClass）。
