Devel::Cover::DB(3) User Contributed Perl Documentation Devel::Cover::DB(3) NAME
Devel::Cover::DB - Code coverage metrics for Perl VERSION
version 1.03 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"); Contructs 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 "; my $f = $cover->file($file); for my $criterion ($f->items) { print " $criterion "; my $c = $f->criterion($criterion); for my $location ($c->items) { my $l = $c->location($location); print " $location @$l "; } } } 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->criteriom, 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).
