NAME
       Devel::Cover::DB - Code coverage metrics for Perl

VERSION
       version 1.36

SYNOPSIS
        use Devel::Cover::DB;

        my $db = Devel::Cover::DB->new(db => "my_coverage_db");
        $db->print_summary([$file1, $file2], ["statement", "pod"]);

DESCRIPTION
       This module provides access to a database of code coverage information.

METHODS
   new
        my $db = Devel::Cover::DB->new(db => "my_coverage_db");

       Constructs the DB from the specified database.

   cover
        my $cover = $db->cover;

       Returns a Devel::Cover::DB::Cover object.  From here all the coverage data may be
       accessed.

        my $cover = $db->cover;
        for my $file ($cover->items) {
            print "$file\n";
            my $f = $cover->file($file);
            for my $criterion ($f->items) {
                print "  $criterion\n";
                my $c = $f->criterion($criterion);
                for my $location ($c->items) {
                    my $l = $c->location($location);
                    print "    $location @$l\n";
                }
            }
        }

       Data for different criteria will be in different formats, so that will need special
       handling.  This is not yet documented so your best bet for now is to look at some of the
       simpler reports and/or the source.

       The methods in the above example are actually aliases for methods in
       Devel::Cover::DB::Base (the base class for all Devel::Cover::DB::* classes):

       o   Devel::Cover::DB::Base->values

           Aliased to Devel::Cover::DB::Cover->files, Devel::Cover::DB::File->criteria,
           Devel::Cover::DB::Criterion->locations, and Devel::Cover::DB::Location->data

       o   Devel::Cover::DB::Base->get

           Aliased to Devel::Cover::DB::Cover->file, Devel::Cover::DB::File->criterion,
           Devel::Cover::DB::Criterion->location, and Devel::Cover::DB::Location->datum

       Instead of calling $file->criterion("x") you can also call $file->x.

   is_valid
        my $valid = $db->is_valid;

       Returns true if $db is valid (or looks valid, the function is too lax).
