本文整理了Java中org.eclipse.jdt.core.Signature.getTypeArguments()方法的一些代码示例，展示了Signature.getTypeArguments()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。Signature.getTypeArguments()方法的具体详情如下：
包路径：org.eclipse.jdt.core.Signature
类名称：Signature
方法名：getTypeArguments

Signature.getTypeArguments介绍

[英]Extracts the type argument signatures from the given type signature. Returns an empty array if the type signature is not a parameterized type signature.
[中]从给定的类型签名中提取类型参数签名。如果类型签名不是参数化类型签名，则返回空数组。
