=head1 NAME

SMS::Send::Driver - Base class for SMS::Send drivers


The C<SMS::Send::Driver> class provides an abstract base class for all
L<SMS::Send> driver classes.

At this time it does not provide any implementation code for drivers
(although this may change in the future) with the exception of some
methods provided to trigger "does not implement method" errors.

However, it does serve as something you should sub-class your driver from
to identify it as a L<SMS::Send> driver.

Please note that if your driver class not B<not> return true for
C<$driver->isa('SMS::Send::Driver')> then the L<SMS::Send> constructor
will refuse to use your class as a driver.

=head1 METHODS


use 5.006;
use strict;
use Carp ();

use vars qw{$VERSION};
	$VERSION = '0.06';


=head2 new

The C<new> constructor is required to be implemented by your driver subclass.

It recieves a set of arbitrary paired params. The values of these params are
assumed to be driver-specific (this is expected to change).

If your driver will need to login to some system, locate hardware, or
do some other form of initialisation to validate the SMS delivery mechanism
exists, it should do so in C<new>.

Should return a new L<SMS::Send::Driver>-subclass object, or die on error.


sub new {
	my $class = shift;
	Carp::croak("Driver Error: $class does not implement the 'new' constructor");


=head2 send_sms

The C<send_sms> method is required to be implemented by your driver subclass.

It recieves a set of param pairs as documented in L<SMS::Send>.

Should return true for either success or fire-and-forget with unknown result,
defined-but-false ('' or 0) for a failed message send, or die on a fatal error.


sub send_sms {
	my $class = ref($_[0]) || $_[0];
	Carp::croak("Driver Error: $class does not implement the 'send_sms' method");
