=head1 NAME
Lintian::Lab::ManifestDiff -- Difference representation between two Manifests
=head1 SYNOPSIS
use Lintian::Lab::Manifest;
my $olist = Lintian::Lab::Manifest->new ('binary');
my $nlist = Lintian::Lab::Manifest->new ('binary');
$olist->read_list ('old/binary-packages');
$nlist->read_list ('new/binary-packages');
my $diff = $olist->diff($nlist);
foreach my $added (@{ $diff->added }) {
my $entry = $nlist->get (@$added);
# do something
}
foreach my $removed (@{ $diff->removed }) {
my $entry = $olist->get (@$removed);
# do something
}
foreach my $changed (@{ $diff->changed }) {
my $oentry = $olist->get (@$changed);
my $nentry = $nlist->get (@$changed);
# use/diff $oentry and $nentry as needed
}
=head1 DESCRIPTION
Instances of this class provides access to the packages list used by
the Lab as caches.
=head1 METHODS
=over 4
=cut
# Private constructor (used by Lintian::Lab::Manifest::diff)
sub _new {
my ($class, $type, $nlist, $olist, $added, $removed, $changed) = @_;
my $self = {
'added' => $added,
'removed' => $removed,
'changed' => $changed,
'type' => $type,
'olist' => $olist,
'nlist' => $nlist,
};
bless $self, $class;
return $self;
}
=item $diff->added
Returns a listref containing the keys of the elements that has been added.
Each element is a listref of keys; this list (when dereferenced) can be
used with the manifest's get method to look up the item.
=item $diff->removed
Returns a listref containing the keys of the elements that has been removed.
Each element is a listref of keys; this list (when dereferenced) can
be used with the manifest's get method to look up the item.
=item $diff->changed
Returns a listref containing the keys of the elements that has been changed.
Each element is a listref of keys; this list (when dereferenced) can
be used with the manifest's get method to look up the item.
=item $diff->nlist
Returns the "new" manifest used to create this diff. Note the manifest is not
copied and may have been changed since the diff has been created.
=item $diff->olist
Returns the "orig" manifest used to create this diff. Note the manifest is not
copied and may have been changed since the diff has been created.
