NAME

       Lintian::ProcessableGroup -- A group of objects that Lintian can process

SYNOPSIS

        use Lintian::ProcessableGroup;

        my $group = Lintian::ProcessableGroup->new('lintian_2.5.0_i386.changes');
        foreach my $proc ($group->get_processables){
            printf "%s %s (%s)\n", $proc->pkg_name,
                   $proc->pkg_version, $proc->pkg_type;
        }
        # etc.

DESCRIPTION

       Instances of this perl class are sets of processables.  It allows at most one source and
       one changes or buildinfo package per set, but multiple binary packages (provided that the
       binary is not already in the set).

METHODS

       Lintian::ProcessableGroup->new ([LAB[, FILE]])
           Creates a group and optionally add all processables from .changes or .buildinfo file
           FILE.

           If the LAB parameter is given, all processables added to this group will be stored as
           a lab entry from LAB.

       $group->add_new_processable ($pkg_path[, $pkg_type])
           Adds a new processable of type $pkg_type from $pkg_path.  If $pkg_type is not given,
           it will be determined by the file extension.

           This is short hand for:

            $group->add_processable(
               Lintian::Processable->new ($pkg_path, $pkg_type));

       $group->add_processable($proc)
           Adds $proc to $group.  At most one source and one changes $proc can be in a $group.
           There can be multiple binary $proc's, as long as they are all unique.

           This will error out if an additional source or changes $proc is added to the group.
           Otherwise it will return a truth value if $proc was added.

       $group->get_processables([$type])
           Returns an array of all processables in $group.  The processables are returned in the
           following order: changes (if any), source (if any), all binaries (if any) and all
           udebs (if any).

           This order is based on the original order that Lintian processed packages in and some
           parts of the code relies on this order.

           Note if $type is given, then only processables of that type is returned.

       $group->remove_processable($proc)
           Removes $proc from $group

       $group->get_source_processable
           Returns the processable identified as the "source" package (e.g. the dsc).

           If $group does not have a source processable, this method returns "undef".

       $group->get_buildinfo_processable
           Returns the processable identified as the "buildinfo" processable (e.g.  the buildinfo
           file).

           If $group does not have a buildinfo processable, this method returns "undef".

       $group->get_changes_processable
           Returns the processable identified as the "changes" processable (e.g.  the changes
           file).

           If $group does not have a changes processable, this method returns "undef".

       $group->get_binary_processables
           Returns all binary (and udeb) processables in $group.

           If $group does not have any binary processables then an empty list is returned.

       $group->info
           Returns $info element for this group.

       $group->init_shared_cache
           Prepare a shared memory cache for all current members of the group.  This is solely a
           memory saving optimization and is not required for correct performance.

       $group->clear_cache
           Discard the info element of all members of this group, so the memory used by it can be
           reclaimed.  Mostly useful when checking a lot of packages (e.g. on lintian.d.o).
