      Cognitive Complexity

      Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.

      A method's cognitive complexity is based on a few simple rules:

      • Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
      • Code is considered more complex for each "break in the linear flow of the code"
      • Code is considered more complex when "flow breaking structures are nested"

      TooManyMethods

      Since: 0.1

      A class with too many methods is probably a good suspect for refactoring, in order to reduce its complexity and find a way to have more fine grained objects.

      By default it ignores methods starting with 'get' or 'set'.

      The default was changed from 10 to 25 in PHPMD 2.3.

          Cognitive Complexity

          Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.

          A method's cognitive complexity is based on a few simple rules:

          • Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
          • Code is considered more complex for each "break in the linear flow of the code"
          • Code is considered more complex when "flow breaking structures are nested"

                                      Cognitive Complexity

                                      Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.

                                      A method's cognitive complexity is based on a few simple rules:

                                      • Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
                                      • Code is considered more complex for each "break in the linear flow of the code"
                                      • Code is considered more complex when "flow breaking structures are nested"

                                                          Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.

                                                          A method's cognitive complexity is based on a few simple rules:

                                                          • Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
                                                          • Code is considered more complex for each "break in the linear flow of the code"
                                                          • Code is considered more complex when "flow breaking structures are nested"

The decision points are 'if', 'while', 'for', and 'case labels'. Generally, 1-4 is low complexity, 5-7 indicates moderate complexity, 8-10 is high complexity, and 11+ is very high complexity.

                                                                                                                                                                Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.

                                                                                                                                                                When you violate DRY, bugs and maintenance problems are sure to follow. Duplicated code has a tendency to both continue to replicate and also to diverge (leaving bugs as two similar implementations differ in subtle ways).

                                                                                                                                                                Tuning

                                                                                                                                                                The threshold configuration represents the minimum mass a code block must have to be analyzed for duplication. The lower the threshold, the more fine-grained the comparison.

                                                                                                                                                                If the engine is too easily reporting duplication, try raising the threshold. If you suspect that the engine isn't catching enough duplication, try lowering the threshold. The best setting tends to differ from language to language.

                                                                                                                                                                See codeclimate-duplication's documentation for more information about tuning the mass threshold in your .codeclimate.yml.

The lower the threshold, the more fine-grained the comparison.

                                                                                                                                                                If the engine is too easily reporting duplication, try raising the threshold. If you suspect that the engine isn't catching enough duplication, try lowering the threshold. The best setting tends to differ from language to language.

                                                                                                                                                                When you violate DRY, bugs and maintenance problems are sure to follow. Duplicated code has a tendency to both continue to replicate and also to diverge (leaving bugs as two similar implementations differ in subtle ways).

                                                                                                                                                                The threshold configuration represents the minimum mass a code block must have to be analyzed for duplication. The lower the threshold, the more fine-grained the comparison.

                                                                                                                                                                If the engine is too easily reporting duplication, try raising the threshold. If you suspect that the engine isn't catching enough duplication, try lowering the threshold. The best setting tends to differ from language to language.

If you suspect that the engine isn't catching enough duplication, try lowering the threshold. The best setting tends to differ from language to language.

                                                                                                                                                                Duplicated code can lead to software that is hard to understand and difficult to change. The Don't Repeat Yourself (DRY) principle states:

                                                                                                                                                                Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.

                                                                                                                                                                When you violate DRY, bugs and maintenance problems are sure to follow. Duplicated code has a tendency to both continue to replicate and also to diverge (leaving bugs as two similar implementations differ in subtle ways).

                                                                                                                                                                Tuning

                                                                                                                                                                This issue has a mass of 97.

                                                                                                                                                                We set useful threshold defaults for the languages we support but you may want to adjust these settings based on your project guidelines.

                                                                                                                                                                The threshold configuration represents the minimum mass a code block must have to be analyzed for duplication. The lower the threshold, the more fine-grained the comparison.

                                                                                                                                                                If the engine is too easily reporting duplication, try raising the threshold. If you suspect that the engine isn't catching enough duplication, try lowering the threshold. The best setting tends to differ from language to language.

                                                                                                                                                                See codeclimate-duplication's documentation for more information about tuning the mass threshold in your .codeclimate.yml.
