Javadoc评论中有多行代码示例 [英] Multiple line code example in Javadoc comment
问题描述
我有一个小代码示例,我想在一个方法的Javadoc注释中包含它。
/ **
* - 例:循环映射对象列表 -
*< ;代码>
* for(int i = 0; i< list.size(); i ++){
* Map map =(Map)list.get(i);
* System.out.println(map.get(wordID));
* System.out.println(map.get(word));
*}
*< / code>
*
* @param查询 - 选择语句
* @return Map对象列表
* /
问题是代码示例显示在Javadoc中,没有换行符使其难以阅读。
- 例如:循环映射对象列表 - for(int i = 0; i list.size(); i ++){Map map =(Map)list.get(i);的System.out.println(map.get( 的wordID));的System.out.println(map.get( 字)); }
参数
查询 - - 选择语句
返回:
地图对象列表
我想我错了,假设代码标签会处理换行符。什么是在Javadoc注释中格式化代码示例的最佳方式?
< pre> 标签,您还应该使用 @code
JavaDoc注释,这对于HTML实体问题会让生活更轻松特别是泛型),例如: *< pre>
* {@code
* Set< String> S;
* System.out.println(s);
*}
*< / pre>
会给出正确的HTML输出:
组<字符串> S;
System.out.println(s);
省略 @code
块(或使用< code>
标记)将产生如下HTML:
Set s;
System.out.println(s); (仅供参考,可以在这里找到Java SE 8标记描述: $ b $> //docs.oracle.com/javase/8/docs/technotes/tools/unix/javadoc.html#CHDJGIJBrel =noreferrer> Javadoc Tags )
I have a small code example I want to include in the Javadoc comment for a method.
/**
* -- ex: looping through List of Map objects --
* <code>
* for (int i = 0; i < list.size(); i++) {
* Map map = (Map)list.get(i);
* System.out.println(map.get("wordID"));
* System.out.println(map.get("word"));
* }
* </code>
*
* @param query - select statement
* @return List of Map objects
*/
The problem is the code example shows up in the Javadoc with no line breaks making it hard to read.
-- ex: looping through List of Map objects -- for (int i = 0; i list.size(); i++) { Map map = (Map)list.get(i); System.out.println(map.get("wordID")); System.out.println(map.get("word")); }
Parameters
query - - select statement
Returns:
List of Map objects
I guess I am wrong in assuming the code tag would handle line breaks. What is the best way to format code examples in Javadoc comments ?
解决方案 In addition to the already mentioned <pre>
tags, you should also use the @code
JavaDoc annotation, which will make life much easier when it comes to HTML entities issues (in particular with Generics), e.g.:
* <pre>
* {@code
* Set<String> s;
* System.out.println(s);
* }
* </pre>
Will give correct HTML output:
Set<String> s;
System.out.println(s);
While omitting the @code
block (or using a <code>
tag) will result in HTML like this:
Set s;
System.out.println(s);
