=head1 NAME
Lintian::Collect::Changes - Lintian interface to .changes file data collection
=head1 SYNOPSIS
my ($name, $type) = ('foobar_1.2_i386.changes', 'changes');
my $collect = Lintian::Collect->new($name, $type);
my $files = $collect->files();
foreach my $file (keys %{$files}) {
my $size = $files->{$file}{size};
print "File $file has size $size\n";
}
=head1 DESCRIPTION
Lintian::Collect::Changes provides an interface to data for .changes
files. It implements data collection methods specific to .changes
files.
=head1 CLASS METHODS
=over 4
=item new (PACKAGE)
Creates a new Lintian::Collect::Changes object. Currently, PACKAGE is
ignored. Normally, this method should not be called directly, only via
the L<Lintian::Collect> constructor.
=cut
# Initialize a new .changes file collect object. Takes the package name,
# which is currently unused.
sub new {
my ($class, $pkg) = @_;
my $self = {};
bless($self, $class);
return $self;
}
=back
=head1 INSTANCE METHODS
In addition to the instance methods listed below, all instance methods
documented in the L<Lintian::Collect> module are also available.
=over 4
=item files
Returns a reference to a hash containing information about files listed
in the .changes file. Each hash may have the following keys:
=over 4
=item name
Name of the file.
=item size
The size of the file in bytes.
=item section
The archive section to which the file belongs.
=item priority
The priority of the file.
=item checksums
A hash with the keys being checksum algorithms and the values themselves being
hashes containing
=over 4
=item sum
The result of applying the given algorithm to the file.
=item filesize
The size of the file as given in the .changes section relating to the given
checksum.
