version 1.20

SYNOPSIS

use DPKG::Log;

my $package = DPKG::Log::Analyse::Package->new('package' => 'foobar');

DESCRIPTION

This module is used to analyse a dpkg log.

METHODS

$package = DPKG::Log::Analyse::Package->new('package' => 'foobar')

Returns a new DPKG::Log::Analyse::Package object.

$package_name = $package->name;

Returns the name of this package.

$package->version

Return or set the version of this package.

$package->previous_version

Return or set the previous version of this package.

$package->status

Return or set the status of this package.

equals($package1, $package2);

print "equal" if $package1 eq $package2

Compares two packages in their string representation.

compare($package1, $package2)

print "greater" if $package1 > $package2

Compare two packages. See OVERLOADING for details on how the comparison works.

$package_str = $package->as_string

printf("Package name: %s", $package);

Return this package as a string. This will return the package name and the version (if set) in the form package_name/version. If version is not set, it will return the package name only.

Overloading

This module explicitly overloads some operators. Each operand is expected to be a DPKG::Log::Analyse::Package object.

The string comparison operators, ``eq'' or ``ne'' will use the string value for the comparison.

The numerical operators will use the package name and package version for comparison. That means a package1 == package2 if package1->name equals package2->name AND package1->version == package2->version.

The module stores versions as Dpkg::Version objects, therefore sorting different versions of the same package will work.

This module also overloads stringification returning either the package name if no version is set or ``package_name/version'' if a version is set.
