Perl::Critic::Utils::McCabe - Functions that calculate the McCabe score of source code.
Provides approximations of McCabe scores. The McCabe score of a set of code describes the
number of possible paths through it. The functions here approximate the McCabe score by
summing the number of conditional statements and operators within a set of code. See
<http://en.wikipedia.org/wiki/Cyclomatic_complexity> for some discussion about the McCabe
number and other complexity metrics.
This is considered to be a public module. Any changes to its interface will go through a
"calculate_mccabe_of_sub( $sub )"
Calculates an approximation of the McCabe number of the code in a PPI::Statement::Sub.
"calculate_mccabe_of_main( $doc )"
Calculates an approximation of the McCabe number of all the code in a
PPI::Statement::Document that is not contained in a subroutine.
