DataClump

This aspect detects data clumps in you codebase.

Data clump is a name given to any group of variables which are passed around together (in a clump) throughout various parts of the program.

Subaspects

This aspect does not have any sub aspects.

Example

        public static void main(String args[]) {

            String firstName = args[0];
            String lastName = args[1];
            Integer age = new Integer(args[2]);
            String gender = args[3];
            String occupation = args[4];
            String city = args[5];

            welcomeNew(firstName,lastName,age,gender,occupation,city);
        }

        public static void welcomeNew(String firstName, String lastName,
                              Integer age, String gender,
                              String occupation, String city){

            System.out.printf("Welcome %s %s, a %d-year-old %s ""from %s who works as a%s
",firstName, lastName, age, gender, city, occupation);
        }

Importance

Data clumps make codes difficult to read, debug, scale, and also hardly reusable.

How to fix this

Formally group the different variables together into a single object.
