A long list of parameters might happen after several types of algorithms are merged in a single method. Please be sure to answer the question. Aren't you bored of reading so much? In Refactoring Martin Fowler 1999 mentions the fact that in the past programmers were taught to pass everything a method required as a parameter because global data was considered evil and painful. In our early programming days we were taught to pass in as parameters everything needed by a routine. Data Clumps. Book Acronym: ISSN/DOI/ISBN: HEC Category: Impact Factor: Get in Touch. 7: Cyclomatic complexity: The method has too many branches or loops. Long parameter lists may also be the byproduct of efforts to make classes more independent of each other. They’re a diagnostic tool used when considering refactoring software to improve its design. Code smells. Requirements for Refactoring • Collective code ownership • Coding standards • Pair programming • Simple design • Tests • Continuous integration • Rested programmers (Beck, page 66) Where to refactor Anywhere that needs it, provided: Long Parameter List Methods that take too many parameters produce client code that is awkward and difficult to work with. [endif]> If you look at these long parameter list examples above, 2 of them are used as constructor. A long parameter list is a code smell. For each code smell, list the line numbers of the code where the smell is focused, identify the design principle(s) that are violated, and; identify some program change that the smell would complicate. Long Parameter List. More. A long list may have been created to control which algorithm will be run and how. We will modify this tool so that it can detect various code smells. Provide details and share your research! But limiting them to a fixed number of lines is a style guide smell and may lead to new code smells: sometimes there are reasons for longer functions (e.g. It's common to see parameter lists grow and grow when a method requires too much data. Not all code smells should be “fixed” – sometimes code is perfectly acceptable in its current form. duplicate code (aka cut and paste code), long parameter list, primitive obsession, and ; magic numbers.
