=head1 NAME

Bugzilla::Keyword - A Keyword that can be added to a bug.

=head1 SYNOPSIS

 use Bugzilla::Keyword;

 my $description = $keyword->description;

 my $keywords = Bugzilla::Keyword->get_all_with_bug_count();

=head1 DESCRIPTION

Bugzilla::Keyword represents a keyword that can be added to a bug.

This implements all standard C<Bugzilla::Object> methods. See
L<Bugzilla::Object> for more details.

=head1 METHODS

This is only a list of methods specific to C<Bugzilla::Keyword>.
See L<Bugzilla::Object> for more methods that this object
implements.

=over

=item C<get_all_with_bug_count()> 

 Description: Returns all defined keywords. This is an efficient way
              to get the associated bug counts, as only one SQL query
              is executed with this method, instead of one per keyword
              when calling get_all and then bug_count.
 Params:      none
 Returns:     A reference to an array of Keyword objects, or an empty
              arrayref if there are no keywords.

=item C<is_active>

 Description: Indicates if the keyword may be used on a bug
 Params:      none
 Returns:     a boolean value that is true if the keyword can be applied to bugs.

=item C<set_is_active($is_active)>

 Description: Set the is_active property to a boolean value
 Params:      the new value of the is_active property.
 Returns:     nothing
