NAME

6       Perl::Critic::Utils::McCabe - Functions that calculate the McCabe score
7       of source code.
8

DESCRIPTION

10       Provides approximations of McCabe scores.  The McCabe score of a set of
11       code describes the number of possible paths through it.  The functions
12       here approximate the McCabe score by summing the number of conditional
13       statements and operators within a set of code.  See
14       <http://en.wikipedia.org/wiki/Cyclomatic_complexity> for some
15       discussion about the McCabe number and other complexity metrics.

IMPORTABLE SUBS

22       "calculate_mccabe_of_sub( $sub )"
23           Calculates an approximation of the McCabe number of the code in a
24           PPI::Statement::Sub.
25
26       "calculate_mccabe_of_main( $doc )"
27           Calculates an approximation of the McCabe number of all the code in
28           a PPI::Statement::Document that is not contained in a subroutine.
