An object of class B<Mail::SPF::Mech::All> represents an SPF record mechanism
of type C<all>.

=head2 Constructors

The following constructors are provided:

=over

=item B<new>: returns I<Mail::SPF::Mech::All>

Creates a new SPF record C<all> mechanism object.

%options is a list of key/value pairs representing any of the following options:

=over

=item B<qualifier>

See L<Mail::SPF::Mech/new>.

=back

=item B<new_from_string($text, %options)>: returns I<Mail::SPF::Mech::All>;
throws I<Mail::SPF::ENothingToParse>, I<Mail::SPF::EInvalidMech>

Creates a new SPF record C<all> mechanism object by parsing the string and
any options given.

=head2 Class methods

The following class methods are provided:

=over

=item B<default_qualifier>

=item B<qualifier_pattern>

See L<Mail::SPF::Mech/Class methods>.

=item B<name>: returns I<string>

Returns B<'all'>.

=item B<name_pattern>: returns I<Regexp>

sub parse_params {
    my ($self) = @_;
    # No parameters.
    return;
}

=item B<text>

=item B<qualifier>

=item B<name>

=item B<stringify>

See L<Mail::SPF::Mech/Instance methods>.
