PUBLIC COMMENTS I have fixed this bug. When a bad parameter name is passed to @param, the following warning is printed: @param argument "paramName" is not a parameter name. When @param is used more than once for the same parameter, the following warning is printed: Parameter "paramName" is documented more than once. ###@###.### 2002-07-18

EVALUATION What is happening here is that starting with 1.4.0, the @param tag requires its first argument to be the parameter name. In this case, the user has specified the parameter type instead. Prior to 1.4.0, the test method parameters were documented as: Parameters: name - -String age - -int With 1.4.1, however, the Parameters heading and entries are missing altogether, with no warning. Javadoc should print a warning when the parameter name specified by @param does not appear in the declaration's parameter list. Suggest a warning such as (of course, the filename and line number should be included): warning: @param argument "String" is not a parameter name Committed to mantis. Changed synopsis from: javadoc does not generate @param to this: Does not generate @param when its first arg is not parameter name ###@###.### 2002-05-30 Changed synopsis from: Does not generate @param when its first arg is not parameter name to this: Does not warn when first argument of @param is not parameter name Removed "REGRESSION" from synopsis, as not generating @param when there is a mismatch is a new feature. ###@###.### 2002-05-31 This bug fix should also handle the case where there is an extra @param tag listed, as the first arg to @param would not correspond to a parameter name. This was discussed on the Javadoc Forum subject "@param". For example: public class ParamBug { /** * Space pad a String. @param S String to pad. @param length Desired minimum length. @param end Should the padding be at the end. @param extra the extra param */ public static String pad(String S, int length, boolean end) { } } ###@###.### 2002-05-31 I have fixed this bug. The bug fix is pending review. ###@###.### 2002-07-08
