本文整理了Java中javax.lang.model.util.Types.asElement()方法的一些代码示例，展示了Types.asElement()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。Types.asElement()方法的具体详情如下：
包路径：javax.lang.model.util.Types
类名称：Types
方法名：asElement

Types.asElement介绍

[英]Returns the element corresponding to a type. The type may be a DeclaredType or TypeVariable. Returns null if the type is not one with a corresponding element.
[中]返回与类型对应的元素。类型可以是DeclaredType或TypeVariable。如果类型不是具有相应元素的类型，则返回null。
