NAME

Perl::Metrics::Simple::Analysis - Contains anaylsis results.

SYNOPSIS

This is the class of objects returned by the analyze_files method of the Perl::Metrics::Simple class.

Normally you would not create objects of this class directly, instead you get them by calling the analyze_files method on a Perl::Metrics::Simple object.

VERSION

This is VERSION 0.1

DESCRIPTION

USAGE

new

  $analysis = Perl::Metrics::Simple::Analsys->new( \@file_objects )

Takes an arrayref of Perl::Metrics::Simple::Analysis::File objects and returns a new Perl::Metrics::Simple::Analysis object.

data

The raw data for the analysis. This is the arrayref you passed as the argument to new();

files

Arrayref of file paths, in the order they were encountered.

file_count

How many Perl files were found.

lines

Total lines in all files, excluding comments and pod.

main_stats

Returns a hashref of data based the main code in all files, that is, on the code minus all named subroutines.

  {
    lines             => 723,
    mccabe_complexity => 45
  }

file_stats

Returns an arrayref of hashrefs, each entry is for one analyzed file, in the order they were encountered. The main_stats slot in the hashref is for all the code in the file outside of any named subroutines.

   [
      {
        path => '/path/to/file',
        main_stats => {
                        lines             => 23,
                        mccabe_complexity => 3,
                        path              => '/path/to/file',
                        name              => '{code not in named subroutines}',
                       },
        },
        ...
   ]

packages

Arrayref of unique packages found in code.

package_count

How many unique packages found.

subs

Array ref containing hashrefs of all named subroutines, in the order encounted.

Each hashref has the structure:

    {
         'lines' => 19,
         'mccabe_complexity' => 6,
         'name' => 'databaseRecords',
         'path' => '../path/to/File.pm',
    }

sub_count

How many subroutines found.

summary_stats

Returns a data structure of the summary counts for all the files examined:

    {
        sub_length      => {
            min           => $min_sub_length,
            max           => $max_sub_length,
            sorted_values => \@lengths_of_all_subs,
            mean          => $average_sub_length,
            median        => $median_sub_length,
            standard_deviation => $std_dev_for_sub_lengths,
         },
        sub_complexity  => {
            min           => $min_sub_complexity,
            max           => $max_sub_complexity,
            sorted_values => \@complexities_of_all_subs,
            mean          => $average_sub_complexity,
            median        => $median_sub_complexity,
            standard_deviation => $std_dev_for_sub_complexity,
        },
        main_complexity => {
            min           => $min_main_complexity,
            max           => $max_main_complexity,
            sorted_values => \@complexities_of_all_subs,
            mean          => $average_main_complexity,
            median        => $median_main_complexity,
            standard_deviation => $std_dev_for_main_complexity,
        },
    }

STATIC PACKAGE SUBROUTINES

Utility subs used internally, but no harm in exposing them for now. Call these with a fully-qualified package name, e.g.

  Perl::Metrics::Simple::Analysis::is_ref($thing,'ARRAY')

is_ref

Takes a thing and a type. Returns true is thing is a reference of type type, otherwise returns false.
