Sum Essential Complexity

API ID: SumEssential
Languages: Ada, Basic, C#, C++, Fortran, Java, Jovial, Pascal, Python, Rust, Web
Targets: Architectures, Classes, Files, Functions, Modules, Packages, Project, Subprograms

Sum of essential complexity of all nested functions or methods.

For example:

class SayHello {
public:
  SayHello() {}
  void printHello();
};

void SayHello::printHello() {
  switch (i) {
    ...
  }
}

void cyclomaticDemo() {
  ...
}

int func();          // declared here, not defined - excluded from aggregates

int main() {
  ...
}

SayHello(), printHello(), cyclomaticDemo(), and main() have Essential Complexity of 1, 3, 1, and 1. func() is only declared, not defined, so it isn't counted. For the SayHello class, the sum is 1 + 3 = 4. For the whole file (sample.cpp), the sum is 1 + 3 + 1 + 1 = 6.

See Max and Average Essential Complexity for the other aggregations.
