Smells such as Inappropriate Intimacy, Variable Re-assign, Clones, Middle Man or Speculative Generality require further research to confirm their contribution. This code smell can’t be sniffed at the start as it is a result of constant changes and feature additions that make that class fat or large. 30. Speculative Generality. I don't think we should use phrases like interested, since code and machines do not have human qualities such as interest or envy. Dispensables are avoidable components whose absence would make the code much more cleaner, readable and efficient. The solution for this particular Code Smell lies on two different approaches, depending on the need of code. Each interface is only implemented by one class.

Code Smells are signals that your code should be refactored in order to improve extendability, readability, and supportability. Speculative Generality; Speculative generality occurs when there is unused code written to support the future needs which never got implemented. Object Refactoring Extract Class. The result is often harder to understand and maintain. Collapse Hierarchy Remedy of Speculative Generality 26. Speculative Generality There is an unused class, method, field or parameter. That is, make your code meet today's requirements, and don't try to anticipate which way tomorrow's requirements will go. That makes sense to me, as implementing an interface adds complexity and, if there is only ever one implementation, one might argue that it adds needless complexity. CCS CONCEPTS • Software and its engineering → Software evolution; KEYWORDS Refactoring, Code Smells, Structural Quality Permission to make digital or hard copies of all or part of this work for personal or PLAY. In this article after publishing what refactoring is, I want to describe what are the known smell codes, then you can find them and fix them. Writing code because you might need it is sometimes called "speculative programming", or "Speculative Generality".Both are not to be confused with a the CPU's "speculative execution". You (Probably) Aren't Gonna Need It. -Speculative Generality The common thing for the Dispensable smells is that they all represent something unnecessary that should be removed from the source code.

A method that is not used anywhere in the code is known as a speculative generality code smell. It makes code harder to understand and maintain. creates the smell Speculative Generality in 68% of the cases. Code smells occur when code is not written using fundamental standards. I found a common pattern used in their code base. Extract Variable. This code smell happens when code is created, but it is not used (or not needed) because we think that “We might need this come day”. 6 What is a Code Smell Used as heuristics to indicate when code should be refactored The phrase “Code Smell” is mainly attributed to Kent Beck in the 90’s (xp fame) 6. new code smell?

Bad Smell is a term that has been used for messy or dirty coding, this term says there is part of the code which needs to be clean in term of future. code smell clusters. Couplers All the smells in this group contribute to excessive coupling between classes or show what happens if coupling is replaced by excessive delegation. Speculative Generality: Write code to solve today's problems, and worry about tomorrow's problems when they actually materialize. Remove Parameter Remedy of Speculative Generality 28. Hinders: comprehension, maintenance XP argues that speculative generality is a smell, and that you aren't going to need it. —Martin Fowler. Program entity (class, method, parameter, code fragment, statement, variable) that is unused in the system. Even more interesting, this interface is not exposed outside. Speculative generality. The cure is of course the better-known YAGNI principle: You Aren't Going to Need It.. NB in that essay, Fowler calls the specific code smell a "presumptive feature". Speculative Generality • Making code more general in case it’s needed later • Unused hooks and special cases make code more difficult to understand • Refactorings In other words, its not exposed as part of the API. Speculative Generality: At times, we over-engineer things like defining a superclass or some code that is not needed currently but we feel it might be useful someday. Speculative Generality You get this smell when people say "Oh, I think we will need the ability to do that someday" and thus want all sorts of hooks and special cases to handle things that aren't required. Oddball Solution: There should only be one way of solving the same problem in your code. [27] proposed a code pattern based . The “code”, could be a feature, superclass or even and interface that is not necessary. - Speculative Generality Code Smell This code smell is about premature optimization, many developers fail to see this one.

Smells such as Inappropriate Intimacy, Variable Re-assign, Clones, Middle Man or Speculative Generality require further research to confirm their contribution. This code smell can’t be sniffed at the start as it is a result of constant changes and feature additions that make that class fat or large. 30. Speculative Generality. I don't think we should use phrases like interested, since code and machines do not have human qualities such as interest or envy. Dispensables are avoidable components whose absence would make the code much more cleaner, readable and efficient. The solution for this particular Code Smell lies on two different approaches, depending on the need of code. Each interface is only implemented by one class. Hinders: comprehension, maintenance; Just delete the code; Speculative Generality. new code smell?

Some notes to be considered during planning are: * Don’t over plan your code. Speculative Generality. ... then it is a good candidate for Data Class code smell. Code Smells are signals that your code should be refactored in order to improve extendability, readability, and supportability. Speculative Generality; Speculative generality occurs when there is unused code written to support the future needs which never got implemented. Object Refactoring Extract Class. The result is often harder to understand and maintain. Collapse Hierarchy Remedy of Speculative Generality 26. Speculative Generality There is an unused class, method, field or parameter. That is, make your code meet today's requirements, and don't try to anticipate which way tomorrow's requirements will go. That makes sense to me, as implementing an interface adds complexity and, if there is only ever one implementation, one might argue that it adds needless complexity. CCS CONCEPTS • Software and its engineering → Software evolution; KEYWORDS Refactoring, Code Smells, Structural Quality Permission to make digital or hard copies of all or part of this work for personal or PLAY. In this article after publishing what refactoring is, I want to describe what are the known smell codes, then you can find them and fix them. Writing code because you might need it is sometimes called "speculative programming", or "Speculative Generality".Both are not to be confused with a the CPU's "speculative execution". You (Probably) Aren't Gonna Need It. -Speculative Generality The common thing for the Dispensable smells is that they all represent something unnecessary that should be removed from the source code.

Speculative Generality • Making code more general in case it’s needed later • Unused hooks and special cases make code more difficult to understand • Refactorings In other words, its not exposed as part of the API. Speculative Generality: At times, we over-engineer things like defining a superclass or some code that is not needed currently but we feel it might be useful someday. Speculative Generality You get this smell when people say "Oh, I think we will need the ability to do that someday" and thus want all sorts of hooks and special cases to handle things that aren't required. Oddball Solution: There should only be one way of solving the same problem in your code. [27] proposed a code pattern based . The “code”, could be a feature, superclass or even and interface that is not necessary. - Speculative Generality Code Smell This code smell is about premature optimization, many developers fail to see this one.

It's fake generality. • Increased Complexity. 13. Writing code that is more abstract than it needs to be is often considered to be code smell called "speculative generality" (also mentioned in the post). Metrics describing the introduction and evolution of anti-patterns in code present a promising opportunity for experimentation. Object-oriented abusers. Speculative Generality. A code smell is a surface indication that usually corresponds to a deeper problem in the system. They describe code in need of refactoring in rich language such as 'Speculative Generality', 'Inappropriate Intimacy' or 'shotgun surgery'. Every class implements an Interface. They don't describe bad programming aesthetics and you can't sniff them out precisely with code metrics. STUDY. Removing code smell is an important task and can be done using automated code review tools. Speculative Generality A classic [code] smell is a method that seems more interested in a class other than the one it is in.

I’m just reviewing a project’s code. The most common focus of the envy is the data." Extract variable can help resolve the Comments code smell. Aside from obvious hygiene and social considerations, in much the same way a strong and unpleasant body smell may be the surface indicator of a deeper medical problem, a strong and unpleasant code smell may be the symptom of relevant weaknesses in the code design. The tool uses a genetic algorithm (GA) to search for the best sequence of refactoring that removes the highest number of code smells from the source code. — Refactoring, Martin Fowler and Kent Beck (page 83). Continuing on our discussion on Code Smells and Refactoring techniques, we will discuss Dispensable in this post. ... speculative generality depends on counting the unused . new code smell? Dead Code. All the smells classified in object-oriented abusers result when the concepts of object-oriented paradigm are applied incorrectly. Such duplicated code reveals a lack of object-orientation and a missed opportunity to rely on the elegance of polymorphism. Everyone loses in the "what if.." school of design.
