本文整理了Java中com.sun.javadoc.Doc.position()方法的一些代码示例，展示了Doc.position()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。Doc.position()方法的具体详情如下：
包路径：com.sun.javadoc.Doc
类名称：Doc
方法名：position

Doc.position介绍

[英]Return the source position of the first line of the corresponding declaration, or null if no position is available. A default constructor returns null because it has no location in the source file.
[中]返回相应声明第一行的源位置，如果没有可用位置，则返回null。默认构造函数返回null，因为它在源文件中没有位置。
