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

Signature.getTypeErasure介绍

[英]Extracts the type erasure signature from the given parameterized type signature. Returns the given type signature if it is not parameterized.
[中]从给定的参数化类型签名中提取类型擦除签名。如果未参数化，则返回给定的类型签名。
