-=head1 NAME
-
-Lintian::Collect::Binary - Lintian interface to binary package data collection
-
-=head1 SYNOPSIS
-
- my $collect = Lintian::Collect->new($name, $type);
- if ($collect->native) {
- print "Package is native\n";
- }
-
-=head1 DESCRIPTION
-
-Lintian::Collect::Binary provides an interface to package data for binary
-packages. It implements data collection methods specific to binary
-packages.
-
-This module is in its infancy. Most of Lintian still reads all data from
-files in the laboratory whenever that data is needed and generates that
-data via collect scripts. The goal is to eventually access all data about
-source packages via this module so that the module can cache data where
-appropriate and possibly retire collect scripts in favor of caching that
-data in memory.
-
-=head1 CLASS METHODS
-
-=item new(PACKAGE)
-
-Creates a new Lintian::Collect::Binary object. Currently, PACKAGE is
-ignored. Normally, this method should not be called directly, only via
-the Lintian::Collect constructor.
-
-=back
-
-=head1 INSTANCE METHODS
-
-In addition to the instance methods listed below, all instance methods
-documented in the Lintian::Collect module are also available.
-
-=over 4
-
-=item native()
-
-Returns true if the binary package is native and false otherwise.
-Nativeness will be judged by its version number.
-
-=item index()
-
-Returns a reference to an array of hash references with content
-information about the binary package. Each hash may have the
-following keys:
-
-=over 4
-
-=item name
-
-Name of the index entry without leading slash.
-
-=item owner
-
-=item group
-
-=item uid
-
-=item gid
-
-The former two are in string form and may depend on the local system,
-the latter two are the original numerical values as saved by tar.
-
-=item date
-
-Format "YYYY-MM-DD".
-
-=item time
-
-Format "hh:mm".
-
-=item type
-
-Entry type as one character.
-
-=item operm
-
-Entry permissions as octal number.
-
-=item size
-
-Entry size in bytes. Note that tar(1) lists the size of directories as
-0 (so this is what you will get) contrary to what ls(1) does.
-
-=item link
-
-If the entry is either a hardlink or symlink, contains the target of the
-link.
-
-=item count
-
-If the entry is a directory, contains the number of other entries this
-directory contains.
