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

Signature.getSignatureQualifier介绍

[英]Returns package fragment of a type signature. The package fragment separator must be '.' and the type fragment separator must be '$'.

For example:

getSignatureQualifier("Ljava.util.Map$Entry") -> "java.util"

[中]返回类型签名的包片段。包片段分隔符必须为“.”类型片段分隔符必须是“$”。
例如：

getSignatureQualifier("Ljava.util.Map$Entry") -> "java.util"
