.SH "NAME"
Lintian::ProcessableGroup \-\- A group of objects that Lintian can process
.SH "SYNOPSIS"

.Vb 1
\& use Lintian::ProcessableGroup;

\& foreach my $proc ($group\->get_processables){

.SH "DESCRIPTION"
.IX Header "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).
.SH "METHODS"
.IX Header "METHODS"
.IP "Lintian::ProcessableGroup\->new ([LAB[, \s-1FILE\s0]])" 4
.IX Item "Lintian::ProcessableGroup->new ([LAB[, FILE]])"
Creates a group and optionally add all processables from .changes
or .buildinfo file \s-1FILE.\s0
.Sp
If the \s-1LAB\s0 parameter is given, all processables added to this group
will be stored as a lab entry from \s-1LAB.\s0
.ie n .IP "$group\->add_new_processable ($pkg_path[, $pkg_type])" 4
.el .IP "\f(CW$group\fR\->add_new_processable ($pkg_path[, \f(CW$pkg_type\fR])" 4
.IX Item "$group->add_new_processable ($pkg_path[, $pkg_type])"
Adds a new processable of type \f(CW$pkg_type\fR from \f(CW$pkg_path\fR.  If \f(CW$pkg_type\fR
is not given, it will be determined by the file extension.
.Sp
This is short hand for:
.Sp
.Vb 2
\& $group\->add_processable(
\&    Lintian::Processable\->new ($pkg_path, $pkg_type));
.Ve
.ie n .IP "$group\->add_processable($proc)" 4
.el .IP "\f(CW$group\fR\->add_processable($proc)" 4
.IX Item "$group->add_processable($proc)"
Adds \f(CW$proc\fR to \f(CW$group\fR.  At most one source and one changes \f(CW$proc\fR can be
in a \f(CW$group\fR.  There can be multiple binary \f(CW$proc\fR's, as long as they
are all unique.  Successive buildinfo \f(CW$proc\fR's are silently ignored.
.Sp
This will error out if an additional source or changes \f(CW$proc\fR is added
to the group. Otherwise it will return a truth value if \f(CW$proc\fR was
added.
.ie n .IP "$group\->get_processables([$type])" 4
.el .IP "\f(CW$group\fR\->get_processables([$type])" 4
.IX Item "$group->get_processables([$type])"
Returns an array of all processables in \f(CW$group\fR.  The processables are
returned in the following order: changes (if any), source (if any),
all binaries (if any) and all udebs (if any).
.Sp
This order is based on the original order that Lintian processed
packages in and some parts of the code relies on this order.
.Sp
Note if \f(CW$type\fR is given, then only processables of that type is
returned.
.ie n .IP "$group\->remove_processable($proc)" 4
.el .IP "\f(CW$group\fR\->remove_processable($proc)" 4
.IX Item "$group->remove_processable($proc)"
Removes \f(CW$proc\fR from \f(CW$group\fR
.ie n .IP "$group\->get_source_processable" 4
.el .IP "\f(CW$group\fR\->get_source_processable" 4
.IX Item "$group->get_source_processable"
Returns the processable identified as the \*(L"source\*(R" package (e.g. the dsc).
.Sp
If \f(CW$group\fR does not have a source processable, this method returns \f(CW\*(C`undef\*(C'\fR.
.ie n .IP "$group\->get_buildinfo_processable" 4
.el .IP "\f(CW$group\fR\->get_buildinfo_processable" 4
.IX Item "$group->get_buildinfo_processable"
Returns the processable identified as the \*(L"buildinfo\*(R" processable (e.g.
the buildinfo file).
.Sp
If \f(CW$group\fR does not have a buildinfo processable, this method returns \f(CW\*(C`undef\*(C'\fR.
.ie n .IP "$group\->get_changes_processable" 4
.el .IP "\f(CW$group\fR\->get_changes_processable" 4
.IX Item "$group->get_changes_processable"
Returns the processable identified as the \*(L"changes\*(R" processable (e.g.
the changes file).
.Sp
If \f(CW$group\fR does not have a changes processable, this method returns \f(CW\*(C`undef\*(C'\fR.
.ie n .IP "$group\->get_binary_processables" 4
.el .IP "\f(CW$group\fR\->get_binary_processables" 4
.IX Item "$group->get_binary_processables"
Returns all binary (and udeb) processables in \f(CW$group\fR.
.Sp
If \f(CW$group\fR does not have any binary processables then an empty list is
returned.
.ie n .IP "$group\->info" 4
.el .IP "\f(CW$group\fR\->info" 4
.IX Item "$group->info"
Returns \f(CW$info\fR element for this group.
.ie n .IP "$group\->init_shared_cache" 4
.el .IP "\f(CW$group\fR\->init_shared_cache" 4
.IX Item "$group->init_shared_cache"
Prepare a shared memory cache for all current members of the group.
This is solely a memory saving optimization and is not required for
correct performance.
.ie n .IP "$group\->clear_cache" 4
.el .IP "\f(CW$group\fR\->clear_cache" 4
.IX Item "$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).
