=head1 NAME
Bugzilla::Status - Bug status class.
=head1 SYNOPSIS
use Bugzilla::Status;
my $bug_status = new Bugzilla::Status({name => 'ASSIGNED'});
my $bug_status = new Bugzilla::Status(4);
my @closed_bug_statuses = closed_bug_statuses();
Bugzilla::Status::add_missing_bug_status_transitions($bug_status);
=head1 DESCRIPTION
Status.pm represents a bug status object. It is an implementation
of L<Bugzilla::Object>, and thus provides all methods that
L<Bugzilla::Object> provides.
The methods that are specific to C<Bugzilla::Status> are listed
below.
=head1 METHODS
=over
=item C<closed_bug_statuses>
Description: Returns a list of C<Bugzilla::Status> objects which can have
a resolution associated with them ("closed" bug statuses).
Params: none.
Returns: A list of Bugzilla::Status objects.
=item C<can_change_to>
Description: Returns the list of active statuses a bug can be changed to
given the current bug status. If this method is called as a
class method, then it returns all bug statuses available on
bug creation.
Params: none.
Returns: A list of Bugzilla::Status objects.
=item C<can_change_from>
Description: Returns the list of active statuses a bug can be changed from
given the new bug status. If the bug status is available on
bug creation, this method doesn't return this information.
You have to call C<can_change_to> instead.
Params: none.
Returns: A list of Bugzilla::Status objects.
=item C<add_missing_bug_status_transitions>
Description: Insert all missing transitions to a given bug status.
Params: $bug_status - The value (name) of a bug status.
Returns: nothing.
