The present documentation present only methods that differs from the Slackware::Slackget::List class.

fill_from_xml

Fill the Slackware::Slackget::PackageList from the XML data passed as argument.

        $packagelist->fill_from_xml(
                '<choice action="installpkg">
                        <package id="gcc-objc-3.3.4-i486-1">

                                        Objective-C support for the GNU Compiler Collection.
                                        This package contains those parts of the compiler collection needed to
                                compile code written in Objective-C.  Objective-C was originally
                                developed to add object-oriented extensions to the C language, and is
                                best known as the native language of the NeXT computer.

Sort

Apply the Perl built-in function sort() on the PackageList. This method return nothing.

        $list->Sort() ;

index_list

Create an index on the PackageList. This index don't take many memory but speed a lot search, especially when you already have the package id !

The index is build with the Package ID.

get_indexed

Return a package, as well as Get() do but use the index to return it quickly. You must provide a package ID to this method.

        my $pkg = $list->get_indexed($qlistviewitem->text(5)) ;

get_indexes

Return the list of all indexes

        my @indexes = $list->get_indexes() ;
