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

Signature.getElementType介绍

[英]Returns the type signature without any array nesting.

For example:

getElementType("[[I") --> "I".

[中]返回没有任何数组嵌套的类型签名。
例如：

getElementType("[[I") --> "I".
