JavaDoc可重用参数值 [英] JavaDoc Reusable Parameter Values

问题描述

好吧，我这里有这个代码，这是我对标准Swing TableModel的替代实现。我认为这是一个绝对的噩梦，我的问题是，我有很多rowIndex和columIndex参数，有没有一种方法可以在它们之间共享描述，以实现更标准化，更少手指工作的方式？谢谢!!

Alright, I have this code here which is my replacement implementation of the standard Swing TableModel. Which I think is an absolute nightmare, my question is, I have many rowIndex and columIndex parameters, is there a way I can share a description between them for a more standardized, and less finger working way? Thank You!!

推荐答案

不可能没有

• 修补标准doclet（或替换你自己的doclet）


• 修补Javadoc核心


• 在将源代码提供给JavaDoc之前预处理源代码


• 后处理HTML输出在运行Javadoc之后。

• patching the standard doclet (or substituting your own one)
• patching the Javadoc core
• preprocessing the source code before giving it to JavaDoc
• postprocessing the HTML output after running Javadoc.
