=head1 NAME

Perl::Critic::PolicyParameter::Behavior::Boolean - Actions appropriate for a boolean parameter.


=head1 DESCRIPTION

Provides a standard set of functionality for a boolean
L<Perl::Critic::PolicyParameter> so that the developer of a policy
does not have to provide it her/himself.

NOTE: Do not instantiate this class.  Use the singleton instance held
onto by L<Perl::Critic::PolicyParameter>.


=head1 METHODS

=over

=item C<initialize_parameter( $parameter, $specification )>

Plug in the functionality this behavior provides into the parameter.
At present, this behavior isn't customizable by the specification.
