NAME
    NetSDS::Message - common mobile message (SMS, MMS, IM)

SYNOPSIS
            use NetSDS::Message;

            ...

            $msg = NetSDS::Message->new(
                    src_addr => '1234@mtsgw',
                    dst_addr => '380441234567@mtsgw',
                    body => $content,
            );

DESCRIPTION
    "NetSDS::Message" is a superclass for other modules implementing API to
    exact structure of some messaging data (i.e. CPA2, SMS, MMS, etc).

    This module implemented to avoid duplication of code providing common
    functionality for all message types like managing addresses, headers,
    preparing reply message and so on.

CLASS API
    new([...]) - class constructor
            my $object = NetSDS::SomeClass->new(%options);

    message_id([$value]) - set/get message id
                $msg_id = $msg->message_id();

    src_addr() - set/get source address
                $msg->src_addr('380121234567@operatorgw');

    src_addr_native() - get native form of source address
                # Set address
                $msg->src_addr('380121234567@operatorgw');

                # Get native form of address
                $phone = $msg->src_addr_native(); # return '380121234567'

    dst_addr() - set/get destination address
                $dst_addr = $msg->dst_addr();

    dst_addr_native() - get native form of destination address
                if ($mo_msg->dst_addr_native() eq '1234') {
                        print "Received SMS to 1234";
                }

    subject() - set/get message subject
                $msg->subject('Hello there');

    media() - set/get message media
        Paramters: new media if set or none if get

        Supported media types: 'sms', 'mms', 'ussd'. In fact media types
        processing is not responsibility of this module and implemented in
        other modules.

    header($name[, $value]) - set/get header
        Paramters: header name, new header value

        Returns: header value

        Message headers implemented as hash reference and contains
        supplementary information about message. All header name characters
        are lowercased and all '-' replaced with '_'.

                # Set header
                $msg->header('X-Beer', 'Guinness');

                # Get this header
                $beer = $msg->header('x_beer');

    format() - get/set message format
        Paramters: new format name

        Returns: format name

        Message format provides is related to transport layer code and
        describe data structure of message body.

        Supported formats:

        sms - generic SMS data for ETSI GSM 03.40 compliant implementations.
        See NetSDS::Message::SMS for details.

        cpa2 - CPA2 compatible structure. See NetSDS::Message::CPA2 for
        details.

    reply() - make reply message
        This message allows to make reply to current one. Source and
        destination message are exchanged, media left the same.

INTERNAL METHODS
    _make_id($system_name) - generate message id
        This method implements automatic generation of message id using
        make_uuid() routine. System name is set to 'netsds.generic' if not
        given in arguments.

EXAMPLES
    See "samples" directory for examples.
