Look for qualified this usages in the same class.
Examples:
/** * * XXX class function description. * */ public class XxClass implements Serializable { private static final long serialVersionUID = 113323427779853001L; /** * id */ private Long id; /** * title */ private String title; /** * find by id * * @param ruleId rule id * @param page start from 1 * @return Result*/ public Result funcA(Long ruleId, Integer page) { return null; } }
