UnknownTracker::UnknownTracker has 76 lines, threshold = 70

Overly long functions make the code harder to read. The recommended maximum function length for the C++ language is 70 lines of code. Severity: Brain Method - Complex Method - Long Method.

We recommend to be careful here -- just splitting long functions don't necessarily make the code easier to read. Instead, look for natural chunks inside the functions that expresses a specific task or concern. Often, such concerns are indicated by a Code Comment followed by an if-statement. Use the EXTRACT FUNCTION refactoring to encapsulate that concern.

The module contains 2 functions with similar structure: BicycleMotionModel::updateStatePoseHead,BicycleMotionModel::updateStatePoseHeadVel

Duplicated code often leads to code that's harder to change since the same logical change has to be done in multiple functions. More duplication gives lower code health.

A certain degree of duplicated code might be acceptable. The problems start when it is the same behavior that is duplicated across the functions in the module, ie. a violation of the Don't Repeat Yourself (DRY) principle. DRY violations lead to code that is changed together in predictable patterns, which is both expensive and risky. DRY violations can be identified using CodeScene's X-Ray analysis to detect clusters of change coupled functions with high code similarity. Read More

Once you have identified the similarities across functions, look to extract and encapsulate the concept that varies into its own function(s). These shared abstractions can then be re-used, which minimizes the amount of duplication and simplifies change.

In this module, 84.6% of all function arguments are primitive types, threshold = 30.0%

Code that uses a high degree of built-in, primitives such as integers, strings, floats, lacks a domain language that encapsulates the validation and semantics of function arguments. Primitive Obsession has several consequences: 1) In a statically typed language, the compiler will detect less erroneous assignments. 2) Security impact since the possible value range of a variable/argument isn't retricted.

In this module, 85 % of all functions have primitive types as arguments.

Primitive Obsession indicates a missing domain language. Introduce data types that encapsulate the details and constraints of your domain. For example, instead of int userId, consider User clicked.

BicycleMotionModel::setMotionParams has 11 arguments, threshold = 4

Functions with many arguments indicate either a) low cohesion where the function has too many responsibilities, or b) a missing abstraction that encapsulates those arguments.

The threshold for the C++ language is 4 function arguments.

Start by investigating the responsibilities of the function. Make sure it doesn't do too many things, in which case it should be split into smaller and more cohesive functions. Consider the refactoring INTRODUCE PARAMETER OBJECT to encapsulate arguments that refer to the same logical concept.

BicycleMotionModel::initialize has 10 arguments, threshold = 4
