Complexity Metrics

Languages: Any
Targets: Architectures, Classes, Files, Project
For the functions in the target project, architecture, or file, report complexity metrics

The function complexity metrics reported by default are:

McCabe Cyclomatic Complexity [aka CC] (Cyclomatic)
Modified McCabe Cyclomatic Complexity [aka CC3] (CyclomaticModified)
Strict McCabe Cyclomatic Complexity [aka CC2] (CyclomaticStrict)
Essential Complexity (Essential)
Max Nesting (MaxNesting)
Paths Log(x) (CountPathLog)

Additional function cyclomatic metrics that can be included are:

Paths [aka NPATH] (CountPath) - note value is truncated at 999,999,999
Stict Modified Cyclomatic Complexity (CyclomaticStrictModified)
Essential Strict Modified Complexity (EssentialStrictModified) - note only applies to Ada
Knots (Knots)
Max Essential Knots (MaxEssentialKnots)
Min Essential Knots (MinEssentialKnots)
Sonar's Cognitive Complexity (CognitiveComplexity) - note this is a metric plugin and may take a longer time to calculate

For project, architecture, and file groups, the following cyclomatic metrics are reported by default

Sum McCabe Cyclomatic Complexity [aka CC] (SumCyclomatic)
Sum Modified McCabe Cyclomatic Complexity [aka CC3] (SumCyclomaticModified)
Sum Strict McCabe Cyclomatic Complexity [aka CC2] (SumCyclomaticStrict)
Sum Essential Complexity (SumEssential)
Max Nesting (MaxNesting)

And the following additional metrics are available

Average McCabe Cyclomatic Complexity [aka CC] (AvgCyclomatic)
Max McCabe Cyclomatic Complexity [aka CC] (MaxCyclomatic)
Average Modified McCabe Cyclomatic Complexity [aka CC3] (AvgCyclomaticModified)
Max Modified McCabe Cyclomatic Complexity [aka CC3] (MaxCyclomaticModified)
Average Strict McCabe Cyclomatic Complexity [aka CC2] (AvgCyclomaticStrict)
Max Strict McCabe Cyclomatic Complexity [aka CC2] (MaxCyclomaticStrict)
Average Essential Complexity (AvgEssential)
Max Essential Complexity (MaxEssential)
Sum Stict Modified Cyclomatic Complexity (SumCyclomaticStrictModified)
Average Stict Modified Cyclomatic Complexity (AvgCyclomaticStrictModified)
Max Stict Modified Cyclomatic Complexity (MaxCyclomaticStrictModified)
